Experiment 1- qualitative analysis of carbohydrates a carbohydrate is an organic compound with the general formula c m (h 2 o) n, that is, consists only of carbon, hydrogen and oxygen, with the last two in the 2:1 atom ratio. Carbohydrates make up the bulk of organic substances on earth and perform numerous roles in living things.

The most abundant are the disaccharides, with two monosaccharide units. The most abundant polysaccharides, starch and cellulose made by plants, consist in determining the biological properties and functions of some polysaccharides.
Carbohydrates can be represented by the stoichiometric formula (ch 2 o) n, where n is the number of carbons in the molecule. Therefore, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. The origin of the term “carbohydrate” is based on its components: carbon (“carbo”) and water (“hydrate”).
