Food is the basic need of all organisms.
Growth, development, maintenance and biotic activities are regulated by food.
The carbohydrate is composed of carbon, hydrogen and oxygen in the ratio of 1:2:1 and a general basic formula Of the carbodydrate is (CH20). The carbohydrates is the main source Of energy and energy required to the body is given by it. The starch, sugar, glucose etc are the examples of carbohydrates. The main source Of carbohydrates are wheat, rice, maize, millet, potato, turnip, beet root, banana etc.
The carbohydrate is Of three types—
1. Monosaccharides : These are the most simple form Of carbohydrate and its general formula is (CH20)n.
There are various examples of monosaccharides like Triose (Glyceraldehyde), Tetrose (Erthrose), Hexose
(Glucose, Fructose, Galactose) etc.
2. Disaccharides : These are made of molecules of monosaccharides and its general formula is C12H22O11. There are various examples Of disaccharides like Sucrose-sugarcane, Maltose, Lactose etc.
3. polysaccharides : These are made of a number of monosaccharides (more than three) molecules and its general formula is (C6H11O5)n. Polysaccharides are extracted from the plants and these are insoluble in water. According to the requirement these can be hydrolised and decomposed into glucose. Thus polysaccharides is used as a Stored
fuel for the energy production. There are also so many examples of polysaccharides like Starch, Glycogen, Cellulose, Chitin etc.
Main Functions Of Carbohydrate
1. To supply energy to the body by the process of oxidation.
2. To work like to store the food in the body.
3. To form nucleic acids and work as raw materials for the production of other Substances.
4. To build the external skeletons in the animals.
