Welcome back next We'll look at the problem which one of the following is not included in carbohydrates. So let's think about that group. Carbohydrates and what makes it up. That includes sugars which range from the one ring monos aka rides. Examples of these include glucose and fructose to the more complex double ring. Di Sacha rights Including sucrose and lactose. As two examples notice this. Oh sending on these tells you the molecule is a sugar. That can be a useful tip if you're ever trying to eliminate answers on a multiple choice question. This group also includes long chain policy aka rides. Examples of these include starch, the long branched poly sacha ride of glucose subunits. It stores energy and plants. Then another policy cried of glucose glycogen is used to store energy in animals. And then another yet another policy accurate of glucose cellulose in which those chains are packed together in fiber als that give plant cell walls they're tough structure. So keeping in mind all of these examples of carbohydrates and what makes up that group. Let's turn to look at our answer choices here, remembering that we're looking for the one that is not a carbohydrate. So choice a table sugar. Table sugar is sucrose, which as we mentioned is a dice aka ride. And so therefore a member of the carbohydrates so we can eliminate that choice. Be cellulose. As we noted, a policy aka ride also carbohydrate. So let's them eliminate that choice. C hemoglobin is a protein found in our red blood cells whose main function is carrying oxygen to our tissues. So that is a protein, not a carbohydrate, so that can be a correct answer. So we'll just finally double check by looking at our final option D glucose, as we mentioned, a monos, aka ride sugar and therefore a carbohydrate, and not our answer. So there we have it. Our answer is hemoglobin, a protein, and not a carbohydrate. Thanks. See you in the next video.
