What is Chemistry For Your Life?

A podcast that helps you understand the fascinating chemistry hidden in your everyday life.

Have you ever wondered why onions make you cry? Or how soap gets your hands clean? What really is margarine, or why do trees change colors in the fall? Melissa is a chemist, and to answer these questions she started a podcast, called Chemistry for your life!

In each episode Melissa explains the chemistry behind one of life’s mysteries to Jam, who is definitely not a chemist, but she explains it in a way that is easy to understand, and totally fascinating.

If you’re someone who loves learning new things, or who wonders about the way the world works, then give us a listen.

Melissa:

Hey. I'm Melissa.

Jam:

I'm Jam.

Melissa:

And I'm a chemist. And I'm not. And welcome to chemistry for your life.

Jam:

The podcast helps you understand the chemistry of your everyday life.

Melissa:

Okay, Jim. I realized that we've had a few episodes in the last month that came from this same listener.

Jam:

Uh-huh. Uh-huh.

Melissa:

It's Sam in. Uh-huh. And I don't know what to tell you. He's just been sending me questions I'm pretty excited about. Yeah.

Melissa:

So this latest one Uh-huh. He actually sent probably years ago.

Jam:

Okay.

Melissa:

At least a year ago.

Jam:

Okay.

Melissa:

Now Sam in you know, he's a friend of ours in real life. He's an avid listener of this podcast, and he is an avid hater of cheese.

Jam:

Yes. This is one of the most the things that people learn about him first, I feel like.

Melissa:

And now everybody who listens to this podcast knows this about Sam in. So a long time ago, he asked me to do an episode on why cheese is so disgusting. Okay.

Jam:

And you refused. Right?

Melissa:

I straight up refused. I said, no.

Jam:

Plus, like, even using the word disgusting in In a scientific publication of some kind, even though it's just a podcast, the is kinda not a very scientific word. It's an opinion y word. Right?

Melissa:

It is an opinion y word. He did Send me an article from Business Insider talking about some researchers who are researching disgust using cheese

Jam:

Mhmm.

Melissa:

But I Didn't really have a chance to look at it, so I don't know. Interesting. They're trying to figure out what disgust is and where it occurs in the brain Okay. Which is different than having an opinion that she's Disgusting.

Jam:

True. True. So it'd be like I guess the better way to say it would be like, Sam has a disorder.

Melissa:

No. Just Sam Sam Sam. Have a disorder. But I did then I don't know why this came back to my brain this week. Uh-huh.

Jam:

And

Melissa:

I started to wonder, maybe it's because we had really good cheese when we went to a local Charcuterie board restaurant.

Jam:

Nice.

Melissa:

Or I don't know. I just love cheese, so maybe I just had cheese on the brain.

Jam:

Yeah.

Melissa:

Okay. So then I started to look into it, and I got very excited

Jam:

Uh-huh.

Melissa:

Because cheese is so chemistry y.

Jam:

Nice. Dude, I've always been curious about this.

Melissa:

Have you?

Jam:

Yeah.

Melissa:

Okay. Well, here we go. So cheese starts with milk.

Jam:

Okay. Did not know that. I'm just kidding. I knew that.

Melissa:

Milk is A bunch of chemistry in and of itself. Uh-huh. I mean, I guess everything is, but it's mostly water. But it also has some other things in it like Lactose, which is sugar

Jam:

Mhmm.

Melissa:

Proteins, calcium

Jam:

Mhmm.

Melissa:

Some fats. That's kind of the main gist of what it's got going in there.

Jam:

Okay.

Melissa:

One of the proteins is called casein

Jam:

Okay.

Melissa:

Or casein. I'm not sure. It's c a s e I

Jam:

n. Okay.

Melissa:

And the casein proteins form these thing called micelles.

Jam:

K. I feel like I've heard both those words before. Casein's in my stomach.

Melissa:

Direct casein when we talked about capsaicin.

Jam:

Okay.

Melissa:

Because Sounds right. Casein helps alleviate the heat From jalapenos.

Jam:

Right. Right. Right. Oh, yeah. Because it's in milk.

Melissa:

It's in milk. That's what people tell you to drink milk. Yeah. My cells, we have talked about before In soap.

Jam:

Right. Okay.

Melissa:

So let's talk about what a micelle is.

Jam:

Okay.

Melissa:

Okay. Now imagine a molecule.

Jam:

K.

Melissa:

It has a polar end on one side And nonpolar and on the other side.

Jam:

Okay.

Melissa:

So we've talked about polar and nonpolar bonds before. A polar bond is what?

Jam:

A polar bond has a heavy concentration of electrons on one side.

Melissa:

Right.

Jam:

And so it has and then not 1 on the other side. Right? So then in terms of it Trying to interact with other molecules and stuff that will affect what it wants to try to connect to? Yes. Something like that?

Jam:

Yes.

Melissa:

Exactly. It's A polar bond has, an uneven distribution of electrons.

Jam:

Mhmm.

Melissa:

So one side is gonna be more negative, and the other side is gonna be more positive.

Jam:

Right. Right. Right.

Melissa:

A nonvolar bond has an equal share of electrons.

Jam:

Right. Right. Right.

Melissa:

So it's not going to be charged. It's neutral throughout.

Jam:

Yeah. Just like more chill overall.

Melissa:

Just more chill overall.

Jam:

Yeah. I know some guys like that.

Melissa:

So when you get a bunch of these casein proteins together, They're gonna form micelles where the nonpolar parts of the bond want to hang out together.

Jam:

Okay. Okay.

Melissa:

And so all those will be sort of pointing inwards.

Jam:

Okay.

Melissa:

And on the outside will be the polar side.

Jam:

And

Melissa:

that is so polar. In fact, it's actually negatively charged.

Jam:

Okay.

Melissa:

Okay. So you kind of have what you end up having is Now it's hard for me to come up with an analogy for this.

Jam:

Okay.

Melissa:

So you're gonna have to do it. Okay. Okay. That's your job for today.

Jam:

Okay.

Melissa:

But you sort of end up with a ball, like a magnet almost. It's negatively charged all around the outside, and the middle of it is neutral.

Jam:

Okay. Interesting.

Melissa:

Now the reason we've heard about micelles before is the same thing happens with soap.

Jam:

Right.

Melissa:

Soap has a polar side and a nonpolar side.

Jam:

Mhmm.

Melissa:

The nonpolar side loves grease and oil and other nonpolar things that stick to our dishes.

Jam:

Right. Right.

Melissa:

And so the soap molecules will huddle up around the grease

Jam:

Uh-huh.

Melissa:

Leaving only the polar side exposed

Jam:

Uh-huh.

Melissa:

And the water washes it away.

Jam:

Right. Right.

Melissa:

So casein does that same thing.

Jam:

Mhmm.

Melissa:

They huddle up together. Their non polar sides are in the middle. Their polar sides are on the outside.

Jam:

K.

Melissa:

And they basically end up being a negatively charged ball.

Jam:

Okay.

Melissa:

Ball of negative charge on the outside.

Jam:

Got it.

Melissa:

So to get cheese, what basically happens is these casein proteins have to stick together.

Jam:

Okay.

Melissa:

But chemically, they don't want to because they're all negatively charged.

Jam:

Right. Right.

Melissa:

Many of us have experienced this before when you try to put 2 magnets together, and the negative charges are on the same side, and they repel each other. That's what those casein micelles are doing in milk. They're repelling each other.

Jam:

Okay. Got it. Tons of just the negative balls that don't wanna be around each other. They're looking for positive stuff. That's what they'd rather have.

Jam:

Yep. Okay.

Melissa:

So they're not gonna stick together, but them sticking together is what we need for cheese.

Jam:

Oh, right. So then it can be, like, a more solid thing.

Melissa:

Exactly.

Jam:

Okay. Okay.

Melissa:

Those proteins sticking together are more solid things just like with eggs cooking.

Jam:

Right. Right. Right.

Melissa:

So we've had an episode about soap that you can review to get more of an idea of the polar or non polar bonds, and we have an episode about what happens when you cook eggs that you can review. I think that one was also from Sam in.

Jam:

Yeah. Yeah. I think I think you're right. Dang, dude.

Melissa:

Sam. Pitched some good episodes.

Jam:

What champ?

Melissa:

He knows how to pique my sense of curiosity. I'm excited. So to be able to get these KC and y cells to stick together, there's 2 chemistry steps that need to happen.

Jam:

Okay.

Melissa:

There's probably a lot more, but I'm gonna boil it down to these 2 chemistry steps. Chemistry step 1, milk Has bacteria added to it. Okay. If it's unpasteurized, there's already bacteria in

Jam:

it. Right.

Melissa:

And that bacteria will break down Lactose, which is the sugar in milk Mhmm. Into lactic acid.

Jam:

K.

Melissa:

So I don't think we need to get into the nitty gritty of how that happens. Mhmm. But the bacteria basically as a byproduct. It eats sugar, and it Spits out lactic acid.

Jam:

Mhmm. Okay.

Melissa:

So that is a chemistry process in and of itself. That's a chemistry step one.

Jam:

Okay.

Melissa:

We're turning sugar into acid. Okay. So if you add acid to something, It's gonna become more acidic.

Jam:

Right.

Melissa:

And that's where chemistry step 2 comes in.

Jam:

Because acids want electrons. Right?

Melissa:

Mhmm.

Jam:

Okay.

Melissa:

So this acid, which is a positive, is going to sort of neutralize the negative charges on the outside of the casing by micelles, and that's gonna allow them to stick together.

Jam:

Okay. Wow. So it There's enough electrons to where all those negative little outer layer, they all have so many.

Melissa:

They have there's so many negative charges.

Jam:

And then all the asset that's new nearly present once the negative charges.

Melissa:

Yep.

Jam:

And then everything stabilizes out.

Melissa:

Mhmm.

Jam:

Woah. Cool.

Melissa:

One thing amazing?

Jam:

Yes.

Melissa:

It's so simple, But it's so complicated and so chemistry y.

Jam:

Yeah. And to think that, like, obviously, like many things we talked about, that was going on for centuries before anyone understood what was happening.

Melissa:

A 100%.

Jam:

Cheese obviously happened naturally at some point. Yep. And then people were like, this tastes good. Let's keep doing it on purpose.

Melissa:

Mhmm.

Jam:

Man, that's cool.

Melissa:

So what this looks like practically, if you've ever seen someone make cheese, they'll have the milk. The bacteria will be added if pasteurized or they'll let it sit. Mhmm. And it will start to the liquid will start to get more clear and watery looking. Mhmm.

Jam:

And

Melissa:

then there will be chunks in it.

Jam:

Okay. Okay.

Melissa:

And those chunks are literally micelles of casein that have started to stick together.

Jam:

Nice.

Melissa:

And in some ways, I think The micelles break down a little bit, and just the casein proteins are sticking to each other more. It doesn't keep its perfect shape once it doesn't have that charge, I think.

Jam:

Okay. Okay.

Melissa:

So those are called curds?

Jam:

Right.

Melissa:

So you get the watery liquid. It's a whey. It's got some other proteins in it and stuff, and then the Casein proteins sticking together.

Jam:

Mhmm.

Melissa:

There's some other stuff in those curds too, not just the casein proteins, but the casein proteins sticking together is what starts to solidify it.

Jam:

Okay.

Melissa:

And then you gather all those up And press them into cheese molds.

Jam:

Uh-huh.

Melissa:

That's cheese molds like shapers, not like

Jam:

mold. Yeah.

Melissa:

Yes. Because that comes into play too. Yeah. And then they let the cheese age. Mhmm.

Melissa:

And the aging process is even more chemistry.

Jam:

Okay.

Melissa:

You're turning more of that lactose into lactic acid.

Jam:

Okay.

Melissa:

The bacteria are as it ages. And the more acidic The cheese gets

Jam:

Mhmm.

Melissa:

The more sharp of a flavor it has.

Jam:

Okay. Okay.

Melissa:

And sometimes they will inject strains of mold into cheese Mhmm. To make something like blue cheese.

Jam:

Right. Right.

Melissa:

So that's the overall chemistry of cheese.

Jam:

Interesting. Dude, wow. Mhmm. That's crazy.

Melissa:

Oh, they do also usually, after they've pressed the cheese into molds, they'll have Salt or something. I think that forms a rind

Jam:

Mhmm.

Melissa:

On the outside.

Jam:

Okay.

Melissa:

And that maybe keeps it from having any kind of aging that you don't want.

Jam:

Got it. Got it.

Melissa:

Basically, it going bad in a uncontrolled manner, I think.

Jam:

Right.

Melissa:

And that's also when the texture is developed as it's aging. Mhmm. So that's the chemistry of cheese.

Jam:

Wow, dude. I like it. That's interesting.

Melissa:

So the bacteria are causing a reaction to happen, And then that reaction creating acid is giving the right conditions for a micelle to Lose that negative charge and the casein proteins to start to stick together.

Jam:

Dang. Yeah.

Melissa:

Wow. Also, the bacteria doing a reaction, That's useful in cheese. People are basically using the bacteria to do their job. Uh-huh. But there's actually a professor at UNT named doctor Liz Skelham.

Jam:

Mhmm.

Melissa:

And she does organic synthesis using bacteria. She makes the bacteria make The chemistry for her.

Jam:

Oh, interesting.

Melissa:

So I think that's another application of a similar process, but it this is cool because The bacteria are doing a chemical reaction, and that chemical reaction is creating the environment that we need

Jam:

Mhmm.

Melissa:

To make cheese, basically.

Jam:

Mhmm. Interesting. Interesting. Wow.

Melissa:

So that's it. That's the chemistry of cheese.

Jam:

Okay. Interesting. I think I think I might have an analogy, but it's a little bit of a stretch.

Melissa:

Okay. Lay it on me. Let's see.

Jam:

But it can't hurt. You know?

Melissa:

Can't hurt. It can't be better than the no analogy I came up

Jam:

With? Yeah. So let's say that milk is like this world we live in. We're all just in a big old glass of milk.

Melissa:

Okay.

Jam:

And all of us are myself.

Melissa:

Okay.

Jam:

What I mean by that is that we Many of us, I guess you could say let's just take a hypothetical group of people, that are not very optimistic people. Okay. They're pretty negative. Pretty pessimistic.

Melissa:

Definitely.

Jam:

I can be that way sometimes. Sorry.

Melissa:

I can be that way too.

Jam:

So imagine a group of people that are all that way in this world of this glass of milk, which is not a stretch. I think that's actually pretty

Melissa:

Definitely.

Jam:

Reasonable to view our world that way. So They all have this negative, like, outer interaction layer.

Melissa:

Right.

Jam:

But if you wanna be a little bit of a more Optimistic person, you have to believe that there's some something inside of them that's a little more chill. A little

Melissa:

Okay. Yeah.

Jam:

More More tender, a little bit more human, a little bit more, not quite as negative.

Melissa:

Right. Definitely.

Jam:

But How is that ever gonna how are we gonna get there? How can we get to that level? Especially when you have tons of people that are negative like that, they don't wanna hang out. They don't want to

Melissa:

I know.

Jam:

Befriend each other. They wanna be on their own.

Melissa:

That's right.

Jam:

Because they don't wanna be around other negative people. They're like, ew, I've got too many opinions about you. Don't wanna be around you. But what happens if you could flood the entire world with something very positive?

Melissa:

Okay.

Jam:

So in the case of milk, we introduce bacteria. Bacteria eats I don't have an allergy for this part. Okay? So bacteria eats

Melissa:

So back off, listeners.

Jam:

Sorry. So bacteria, we maybe could add into this. If you're a listener and you're thinking, oh, I've got a perfect Addition.

Melissa:

He was just so defensive straight out. He said, I don't have an allergy for this. Okay?

Jam:

So this part, just the Bacteria eating the lactose Mhmm. And turning into lactic acid.

Melissa:

Yes.

Jam:

Don't have a knowledge of that part. So something really positive happens. Lactoacid is very positive. Yep. So Imagine just some really good vibes are introduced into the world.

Jam:

Nice. Something super positive, love, whatever it is.

Melissa:

Chocolate.

Jam:

Chocolate. Something that really softens that negative layer we've got around ourselves. Yeah. It neutralizes it.

Melissa:

Neutralizes it.

Jam:

It's just just too positive. It can't you can't you can't resist.

Melissa:

Yeah.

Jam:

And then all that negativity's gone away, and you start to notice, like, hey. All these people around me, they're kinda cool. They're not they're not so bad. Let's hang out. And slowly, all these groups of people start hanging out because they're not as negative as they were before.

Jam:

They start being able to get along Yeah. Really well. And, and then they form these Kurds or as we call it, like, communities.

Melissa:

That's great.

Jam:

And then we press them into, That's where the algae breaks down again. Press them into these molds that Mhmm. Form the cheese into shapes and aids them. And And

Melissa:

and cut some basalt.

Jam:

Cut some basalt. Yeah.

Melissa:

Yeah. I like that. That's a good analogy. I was Trying to think of something structural like

Jam:

Yeah.

Melissa:

A bike or something.

Jam:

Right. Right. Right.

Melissa:

Bike wheel. You know? It's got that. But None of those really made sense, but I think that does make sense.

Jam:

I feel like it's not a structural like, there's definitely more details to the structure, of course.

Melissa:

Right. But

Jam:

I did think about how We all have an outer way that we present ourselves and talk and say things Mhmm. That often vary from our inner version. And, Again, that kinda personifies molecules and stuff, which we talked about as being not always everybody's favorite. Not all chemists like that.

Melissa:

Yeah.

Jam:

But for me it. Yeah. And you said that. Yeah. For me, it helps me relate to it more or whatever.

Melissa:

Well, that's why I like it. I know we don't need to personify them, and as long as we can Keep in mind that they are not people. They are atoms, and they don't have wills or excite well, they have excitement, but not the same way we excitement. Yeah. They don't have desire or will.

Melissa:

They're kind of like jellyfish. They just float along and experience what happens to them.

Jam:

Mhmm. Mhmm.

Melissa:

But if it helps People understand, then I wanna use every tool we have to do that. Yeah. But I thought I like this one. It felt like a more old school kind of lesson, one of the more early Kinds of lessons we did.

Jam:

Totally.

Melissa:

And I just thought it was interesting and really fun that Jesus of chemistry e. I also wanna give you some fun facts.

Jam:

Okay. Sweet.

Melissa:

So pH is a measure of acidity.

Jam:

Mhmm.

Melissa:

And so cheese starts to form. The micelles start to stick together Mhmm. At around a pH of 5.3.

Jam:

Okay. And

Melissa:

then it seems like full coagulation takes place at pH of 4.6. I might need some time with that pH, but Uh-huh. That's the pH. So that's just an idea of the pH at which it starts So stick together.

Jam:

Nice. Nice.

Melissa:

And softer cheeses are meant made by coagulating slower. Mhmm. So, like, cream cheese would be a slow coagulating cheese.

Jam:

Oh, I see. Okay.

Melissa:

Harder cheeses need to coagulate faster.

Jam:

Mhmm.

Melissa:

So those cheeses get something added to it called rennet.

Jam:

Mhmm.

Melissa:

And Rinette works by sort of snipping the negative part off of the micelles Mhmm. So they'll come together even quicker.

Jam:

Oh, interesting. Who's got some

Melissa:

help? Yeah. So I thought it was interesting. Maybe we can go more in-depth on how that works in a later episode or something.

Jam:

Yeah.

Melissa:

And I also wanna say it's not just casein proteins in the cheese. There's other stuff too. But the casein protein sticking together

Jam:

Mhmm.

Melissa:

Is what forms the more solid cheese structure.

Jam:

Okay. Okay.

Melissa:

So I think that's pretty cool.

Jam:

Dude, yeah. Very cool. That's awesome. This was very, very interesting. I think, also, I'm probably a little bit more partial to any of our food related ones.

Melissa:

Oh, yeah.

Jam:

There's just something about it. It's like, 1, it's every day, and 2, it just food's interesting. You know? But

Melissa:

And I think that means I think food scientist, you guys can correct me if I'm wrong. That would mean that cottage cheese is basically you're looking at the very early stages of Casey and myself starting to stick

Jam:

to it. Because there's, like, lots of little curds.

Melissa:

Uh-huh. You're You're looking at Uh-huh. Casein micelles clumped up

Jam:

Yeah.

Melissa:

With some other stuff in them, obviously.

Jam:

Right. Right. But, yeah, it looks like so much more milky than other Yeah. Cheeses do. So

Melissa:

yeah. I think. That's my speculation. I did not Confirm that.

Jam:

Yeah.

Melissa:

Great. Well, this is a fun episode, so thanks for that, Sam. Do you have any fun things from your week to go with it?

Jam:

I do. So this week, we had a birthday party for my son, and he turned 1, which we talked about, I think, on a previous episode, but we had the birthday party later.

Melissa:

Mhmm.

Jam:

Millennials have kinda rediscovered him over the past, like, 4 years or so.

Melissa:

So just so positive. Speaking of something positive loving the world.

Jam:

Seriously, mister Rogers. That's a great yeah. There we go. Let's take that analogy all the way home. Go watch mister Rogers.

Jam:

Go watch the documentary or the Tom Hanks movie.

Melissa:

Either one will get you Yeah. It's a cheer jerker.

Jam:

Oh, totally. So we had a birthday party. It was a lot of fun. We had some friends that, most of them are just people who that Like, it was a really good excuse to have them come to Denton that don't live in the in town. Yes.

Melissa:

Yeah.

Jam:

And then other friends, of course, are ones that we get to see all the time.

Melissa:

Right.

Jam:

Melissa made some really cool desserts.

Melissa:

Oh, yeah.

Jam:

She made some mister Rogers sweater cookies

Melissa:

Those are so fun.

Jam:

Which were looked so so cute. And, also, Mason helped.

Melissa:

Yes. And we made trolleys.

Jam:

And trolleys, which I think most of the trolleys got eaten first for some reason.

Melissa:

Like, else? Uh-huh. I thought they wouldn't be this exciting because they had less icing on them.

Jam:

Maybe it's just a little bit less human. Like, I'm not eating

Melissa:

Oh, yeah.

Jam:

I'm not eating a torso.

Melissa:

You know?

Jam:

But, anyway, that was really fun. He and then Wilson made a cake for him, and he ate it in the most funny way. He, like, Ate all of the fruit pieces off first.

Melissa:

Mhmm.

Jam:

And then once he had done that, he realized he could pick up the entire cake and then, Like, just trying to shove it in his mouth.

Melissa:

Because it was an angel food cake, so it was light. Mhmm. That was a request by Jam. That was a good call. The angel food cake was a good idea.

Jam:

And he ended up loving it, which was awesome. And and, yeah, it was just so funny. But the whole, like, thing you hope kids do Mhmm. Like, pick it up and get really messy and stuff, Just took him a while to get there because he was like, oh, I love fruit. Let's eat this fruit first.

Melissa:

And add some whipped cream too.

Jam:

So, anyway, it was It was a lot of fun. I could probably go on for a long time, but it was definitely a lot of fun. So thank you for all the awesome desserts you made.

Melissa:

So welcome. It was really fun to make those desserts, Actually. So Dang.

Jam:

I'm glad you like it. I'm glad you have fun doing that because that is not, for me, not fun.

Melissa:

I really enjoy it, and it was fun to do that with Mason too. You know, for a long time, I would just bake by myself.

Jam:

Uh-huh.

Melissa:

So baking would usually involve staying up late and listening to a murder podcast alone in whatever kitchen.

Jam:

Mhmm.

Melissa:

And this time, I had company, so it's a lot better.

Jam:

Nice. Nice. And he's good at the icing stuff too.

Melissa:

He's very artistic, so it was nice to have him around to help with That.

Jam:

That'd be hard. That's I mean, I like I'm artistic also, but the idea of trying to be, like, really careful on something like a cookie or whatever

Melissa:

Yeah.

Jam:

Not my thing. So you guys did a great job.

Melissa:

He's Good at precision operations.

Jam:

Mhmm. Mhmm.

Melissa:

Well, my thing from this week is pretty different. You guys may have seen it already, seen about it on Twitter. But I not I, we.

Jam:
