3. DEFINITION:
Carbohydrates or sugars are polyhydroxy aldehydes or ketones.
It’s a group of compound occurring in living tissues and food in the form of starch,
cellulose and sugars .
Emperical formula of carbohydrates is CH2O
Carbohydrates hydrolyses into simplest sugar (monosaccharide) called glucose.

4. Classification:
carbohydrates
simple Complex Oligosaccharides
Monosaccharide Disaccharide Polysaccharide
Criteria : No. of sugar units
(1 sugar unit) (2 sugar units) (10 or more units)
(2 to 5 units)
