Hi, it’s Mr. AnDeRsAn in this podcast. I’m going to talk about CARBOHYDRATESSSSSSS when I say the word CARBohydRaTeS, you might think about the starch that’s found in this bread or maybe in this pasta. (GoD tHe SciEnCE) As a biology teacher, I immediately think of SuGAR because that’s going to be the BUilDiNg BLocKs? upon which most carbohydrates are made But you>MusT NeEdWTFISTHAT anDeRsOn:3 Sugars in science, we call

LiStEn CHirEn saccharides and the reason I wrote
WHats The ReaSOn carbohydrates inside these hexagons is that that’s how sugars are essentially put together and so if we have just one of these sugar molecules
>>DaMnn ANderSON>>oOoOoOOOOoO Lacawhat nOW:3>:3>:3 And so you’re going to feel a little irritation in your gut and that’s because we can’t break it down now that seems to be there’s some really cool studies You could read on on lactose Tolerance or intolerance And it’s been naturally selected in other words if your ancestors had domesticated cattle it made sense for them to Drink milk later on in their life, but most people just drink milk when they were young and [so] they quit producing that lactase enzyme Okay, let’s go to Oligosaccharides oligosaccharides are going to be like three to ten different sugar molecules They’re important in Biology in one Pretty important part and that is in the production of these which are called glycoproteins, so we’re in a cell membrane and these which are going to be glycol lipids if you look at the glyco part or the Sugar part that’s going to be just a few sugar Molecules attached together And these are really important for example attaching to the extracellular Matrix. They’re important in identifying what type of a cell it is Here’s an interesting note. I learned on Wikipedia if you were to eat carrots carrots are a wonderful wonderful source of oligosaccharides However, you can’t get the sugar molecules out of it until you’ve cooked the carrots for about an hour to release those oligosaccharides But again, if you’re not getting them in your diet We can synthesize those inside the cell now let’s look at this number right here as we go from Oligosaccharides to Polysaccharides and look how how much that jumped and so when we’re talking about starch for example? What is starch starch is going to be? Hundreds of these glucose molecules attached over and over and over again and so the starch that’s found in a potato Or if we dry it out It’s going to look like this is going to be hundreds of sugar molecules attached over and over and over again now Why are plants doing this? Why are they making these large molecules? They’re storing energy in the starch molecule
OkaY iM DoNe So they can use it by chopping it down into individual monosaccharides now can we do that? you bet. We’ve got glycogen. So glycogen is essentially a
ByE dAd Macro Macro Molecule, and so it’s going to have thousands of glucose molecules Attracted together chemically bonded together you can see what how monstrous this looks with all these individual glucose molecules And we’re going to store that in the liver and so if you are Carbo loading, what are you really doing? You’re eating a bunch of starch, you’re breaking those down into monosaccharides, and then you’re reattaching those again And you’re storing them in our liver as glycogen and so we can get to those stores eventually when we need it We can chalk chop up those monosaccharides, and we can use them in the cell But we also get structure remember and so cellulose that makes up that structure in a lot of plants you can see here It’s going to be a bunch of sugar Molecules attached over and over again But we’re going to have these hydrogen bonds
