3. Outline
 What is carbohydrate?
 Classification of carbohydrate
 Monosaccharide
 Oligosaccharide
 Polysaccharide
Biological role of carbohydrate

4. What is Carbohydrate?
 “Carbohydrate” mean hydrated of carbon.
 They are rich in “carbon” and “hydrogen”.
 They also contain nitrogen and sulfur too.
 They are also knows as energy rich
compound.
 There general formula is Cn(H20)n.
 “Polyhydroxy aldehyde or ketone is called
Carbohydrate”

5. Classification of carbohydrate
 There are three type of carboydrate.
 Monosaccharide.
 Oligosaccharides.
 Polysaccharides.

6. Monosaccharide
 They cannot be further hydrolyzed into
simpler sugars.
 General formula Cn(h2o)n.
 They contain 3 to 7 sugar molecule.
 Chemically, either they are Polyhydroxy
Aldehyde or Ketone.
 The sugar which contain aldehyde group
contain Aldo-sugar. And with a ketone group is
called keto-sugar
 Sweet in taste, and insoluble in water

7. Oligosaccharides
 These are carbohydrate which on hydrolysis
give 2-10 monosaccharide residues.
 They are comparatively less sweet in taste.
 They are comparatively less soluble in water.
Classification of oligosaccharide:
 Disaccharides.
 Trisaccharides.
 Tetrasaccharides.

8. Example of Oligosaccharide

9. Polysaccharide
 The carbohydrates which on hydrolysis give more
than ten monosaccharide residues.
 They are more complex compound.
 They are most abundant carbohydrate in nature.
 They have general formula (c6H1005)n.
 They have branched structure and are usually
tasteless.
 They are only sparingly soluble in water.

10. Classification of polysaccharide
 Polysaccharide are further classified into two
group.
 Homopolysaccharides (homoglycans).
 Hetropolyssharides (hetroglycans).

11. Biological role
 Carbohydrate are rich in C-H, which store energy.
They are excellent source of energy.
 Cellulose is an excellent building material and
form solid, protective and supportive structure of
plant e.g. cell wall
 Glucose is present in blood and its level (0.08%) is
essential for the normal functions of life.
 Carbohydrate combine with lipid and proteins to
form complex conjugated molecule i.e. glycolipid
and glycoprotein. Which form membrane of cell.
