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 Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars.Other carbohydrate molecules are very large (polysaccharides such as starch and cellulose). Carbohydrates are: 1  a source of energy for the body e.g. glucose and a store of energy, e.g. starch in plants.2  building blocks for polysaccharides (giant carbohydrates), e.g. cellulose in plants and glycogen in the human body.3  components of other molecules eg DNA, RNA, glycolipids, glycoproteins, ATP.arbohydrates are: 1  a source of energy for the body e.g. glucose and a store of energy, e.g. starch in plants. 2  building blocks for polysaccharides (giant carbohydrates), e.g. cellulose in plants and glycogen in the human body. 3  components of other molecules eg DNA, RNA, glycolipids, glycoproteins, ATP.
