CARBOHYDRATES (Biochemistry of Carbohydrates: Introduction, Properties, Classification and Biological Significance) Carbohydrates are polyhydroxy aldehydes or ketones. These sugars can be in form of Glucose, Sucrose, Fructose, Cellulose, Maltose etc. Carbohydrates are used to form structural elements, such as chitin in animals and cellulose in plants. Monosaccharides serve as fuel for cellular metabolism. This classification is as follow: Now as we previously discussed, carbohydrates are absolutely essential for life on the planet. Food, shelter and clothing? Therefore it cannot open up the ring structure and react with the reagent. carbohydrate. carbohydrate. The general formula for carbohydrate is Cx(H2O)y. Monosaccharides may be converted into space-saving polysaccharides, such as glycogen and starch. Carbohydrates definition in chemistry. Since hydrogen and oxygen are present in the same proportions as in water, it was believed that this group of compounds could be chemically described as hydrates of carbon. In this context, carbohydrates include table sugar, jelly, bread, cereal, and pasta, even though these foods may contain other organic compounds.

Revise With the concepts to understand better. If the hydroxyl group is on the left of the molecule, it is an L sugar. For example, cereal and pasta also contain some level of protein. In addition, the carbohydrate may exist in either a straight chain or a ring structure. These molecules provide stored energy for plant and animal cells. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. Carbohydrates are found in food, especially so-called starchy foods. As a result, the modern definition of a CARBOHYDRATE is that the compounds are polyhydroxy aldehydes or ketones. The main classification of carbohydrate is done on the basis of hydrolysis. H2O)n, where n is three or greater. The carbohydrates are a group of naturally occurring carbonyl compounds (aldehydes or ketones) that also contain several hydroxyl groups.
