How do you identify a carbohydrate by its name?
The term carbohydrate also implies its chemical makeup which is carbon, hydrogen and oxygen. Carbohydrates can be recognized because the hydrogen to oxygen ratio in their molecules is 2:1. These compounds are organic and provide living things with energy. One can recognize a sugar molecule by its name, which ends in the suffix ose. Two examples include glucose--a molecule used in cellular respiration to yield A.T.P. and fructose, the sugar found in fruit. Both glucose and fructose are called monomers, made of a single sugar molecule and are considered simple sugars. When two sugar molecules are joined together chemically, a disaccharide forms. For example, table sugar or sucrose is a disaccharide. When many sugars are joined in a long chain, this is known as a polysaccharide. Starch and glycogen are examples of polysaccharides. Starch is a molecule that contains stored energy in plants and glycogen is stored energy found in animals. Cellulose, the material found inside cell walls, is another important carbohydrate.
