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.hey 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.
Carbohydrates are molecules which are primarily comprised of the elements carbon, hydrogen, and oxygen. The ratio of carbon to the hydrogen and oxygen elements is 2:1, a stable double bond.
