  • carbohydrates - 385 Words
    A carbohydrate is an organic compound made up of only carbon, hydrogen and oxygen. The monomers for carbohydrates are alpha glucose and beta glucose, these monomers are joined together by glycosidic bonds. Carbohydrates are known as the term saccharides, they are split into chemical groups: monosaccharides, disaccharides and polysaccharides. Monosaccharides are the smallest, examples in this group are: fructose glucose and galactose. To form disaccharides (examples such as: sucrose, lactose...

    Intro: Carbohydrate, any of a large group of compounds in which hydrogen and oxygen, in the proportions in which they exist in water, are combined with carbon; the formula of most of these compounds may be expressed as Cn(H2O)n. Structurally, however, these compounds are not hydrates of carbon, as the formula would seem to indicate. Carbohydrates, as a class, are the most abundant organic compounds found in nature. They are produced by green plants and by bacteria using the process known as...

    Complex Carbohydrates PERSONAL SUMARY: There is a very real difference between simple and complex carbohydrates. Let's look at them. Simple carbohydrates, found in rice, pasta, white potatoes, and some dairy products, contain sugars that are broken down quickly by your body. This will provide your body with a quick burst of energy, but if the carbohydrates are not used quickly, the sugar will turn to fat. That's why low-carb diets cut them out. But those diets often lump all carbs together...

  • Iodine Test for Starch - 497 Words
    Iodine Test for Starch Introduction and Hypothesis: In this experiment, we used iodine to test for starch in certain solutions. Iodine separates starch from polysaccharides, monosaccharides, and disaccharides. Starch is a curled polymer of glucose and iodine interacts with molecules, which changes the color of the molecules to a kind of black color. Iodine does not respond with carbohydrates that are not curled or coiled, thus the color stays yellowish brown. A black color result means that...

    Carbohydrates are macromolecules whose basic units are called monosaccharides (or simple sugars). These simple sugars are polyhydroxy aldehydes (aldoses) or ketones (ketoses), depending on the chemical nature of their carbonyl group, containing at least three carbon atoms. The smallest monosaccharides with only three carbon atoms are collectively known as trioses; while those with four, five, six, and so on carbon atoms are called tetroses, pentoses, hexoses and so on, respectively....

A positive test with Benedict's reagent is readily discerned when the solution changes from a blue color to brick red as the reduced copper...

    What is diabetes? In simple terms diabetes prevents your body converting sugars and starches in your food into energy. The body uses insulin to do this. When diabetes is present the body fails to produce insulin or the insulin it does produce doesn’t work properly (insulin resistance). When we eat food some special cells in our pancreas should produce insulin. The insulin transports glucose, made from carbohydrates in the food, into the cells, where it can be used by the body for energy....

For example, let us say that there are 500 units of sugar in the food that a person eats. Let us assume that out of these 500, 100 become good sugars and 400 become bad sugars during the digestion. These 500 sugars mix in the blood. Let us assume that there is no stored glycogen available in his body. What will happen now? The 100 good sugars will get insulin...
