Carbohydrates are organic molecules that provide energy to all living organisms. They are made up of carbon, hydrogen and oxygen molecules. Carbohydrates are grouped into three main categories on the basis of number of carbon atom present in the molecules. The three categories are monosaccharide, disaccharide, and polysaccharide.
