Carbohydrates: The Monosaccharides. The term carbohydrate was originally used to describe compounds that were literally hydrates of carbon because they had the empirical formula CH 2 O. In recent years, carbohydrates have been classified on the basis of their structures, not their formulas.
Carbohydrates are one of the four major classes of organic compounds in living cells. They are produced during photosynthesis and are the main sources of energy for plants and animals. The term carbohydrate is used when referring to a saccharide or sugar and its derivatives.Carbohydrates can be simple sugars or monosaccharides, double sugars or disaccharides, composed of a few sugars or oligosaccharides, or composed of many sugars or polysaccharides.he most common disaccharide is sucrose. It is composed of glucose and fructose. Sucrose is commonly used by plants to transport sugar from one part of the plant to another. Disaccharides are also oligosaccharides.
