Classification of Carbohydrates - Video Tutorials & Practice Problems

Classification of Carbohydrates Concept 1

Hey, everyone. So here we're going to say that carbohydrates can be classified into four classes. The first class we'll talk about is the monosaccharide. A good example of this would be fructose or glucose. Now, here we have this hexagon which is just a representation of the cyclic forms that these different classes of sugars can take. Later on, we'll go into greater detail on what elements are found within these hexagons. What kind of shapes and what kind of connections do they have to other molecules? Are hexagons the only shape. So talking about mono sac rides the description is they're the simplest of the carbohydrates. They consist of only one unit of sugar and because of that, they cannot be broken down to simpler units. Next, we have our die saccharide die. We know that means two good example. Here will be sucrose or lactose. Here it's two monosaccharide connected together. We can see that through this bond here. Later, I'll go into greater detail on what exactly does that bond look like? And what is the name? And then if we're gonna talk about the description here, we're gonna say it consists of two monosaccharide units connected together. The third class are your illegal sac rides. Now, here we have in this example, three hexagons connected together, but they themselves can consist of 3 to 10 monosaccharide connected together. Here we have just an example. This is Rafas as an example of an illegal saccharide. Then finally, we have polysaccharide, a polysaccharide. Good examples are starch glycogen or cellulose. Here we can see that we have several hexagon rings connected to one another. So we're gonna say here the description is, it consists of large monosaccharide units. We can have up to 10,000 units and we're gonna say it can be branched later on we'll talk about not only do they connect each other in this fashion, but there can be additional branching or additional bonds from other places on the Hexagon circle or her Hexagon rink. So these would be the four types of classes of carbohydrates starting with our simplest ones, we have monosaccharide. Then di saccharide is two of them connected. A legal saccharide can be 3 to 10 of them. And then we have our polysaccharides which are large molecules so greater than 10. All right. So keep this in mind when we're discussing the different types of monosaccharide dys illegal sac rides and polysaccharides that exist

Classification of Carbohydrates Example 1

Here in this example, question, it says classify each carbohydrate as monosaccharide di saccharide illegal saccharide or polysaccharide. Now, in the first one, it says it's water soluble fiber containing three carbohydrate units. So remember this is in line with an illegal saccharide, illegal saccharide is composed of 3 to 10 carbohydrate units or monosaccharide units. Next, this carbohydrate is found in animal tissue and is highly branched. We talked about branching when it came to the polysaccharide class of carbohydrates. Next, it says formed by the combination of one glucose and one fructose unit. Oo these are two sugar units, there's two of them. So this would have to be a die saccharide. And then finally, here it says, produced by hydrolysis of sugar naturally found in milk. All right. So we have the hydrolysis of sugar naturally found in milk. So here this would have to be a monosaccharide by process of elimination. It's the only one left out of all our options. So here we'd say illegal saccharide, polysaccharide disaccharide and finally, monosaccharide as the answer to these four statements
