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.
Sucrose the Chemical. Carbohydrates are biological molecules made up largely of carbon, hydrogen, and oxygen. Monosaccharide sugars are rings of carbon, sometimes with an oxygen atom in the ring, with additional carbon, hydrogen, and oxygen branches. The molecular formula of sucrose is C12H22O11. The fructose and glucose rings are linked to each other by an oxygen atom. As a solid, sucrose typically crystallizes.
