2. Hydrates of carbon containing CnH2nOn.
De oxyribose -important sugar in DNA,
C5H1004.
Carbohydrate is a organic compound that is
made of carbon, oxygen and hydrogen.

5. Monosaccharide
Disaccharide
Oligosaccharide
Polysaccharide

6. Simple sugar.
On the basis of carbon atom–
Trioses- glyceraldehyde.
Tetroses- erythroses
Pentoses- Ribose
Hexoses- Glucose
Heptoses- Glucoheptose

10. Oligo means “few”.
Saccharides means sugar.
Composed of 3-10 sugar unit.
Example- Rhamnose, Raffinose.
Less sweet in taste.
Less soluble in water.

12.  > 10 sugar unit.
 Can divided into two-
 Homo-polysaccharide- composed of same sugar unit.
 Example- starch, glycogen, cellulose, dextrin, chitin.
 Hetero-polysaccharide- composed of different sugar unit.
 Example- agar, aganose, heparin.
 Sources- rice, cereal, bread.

15. Glucose is a energy source.
Glycogen is used as a energy storage form of
carbohydrates in the liver and muscles.
Monosaccharide provides short term energy.
Heparin act as a anticoagulant.
Starch- storage of carbohydrates in in plant.
Inulin –used in measurement of GFR.
Lactose- milk sugar, nutrition to the younger
baby.
