- They are readily absorbed by the body when consumed
ii) Oligo saccharides
- Oligo means few and saccharides means sugars
- They are slowly digested through action of bacteria resulting in production of gas in the stomach condition called flatulence.
iii) Polysaccharides
- They are made up of long chains of sugar units eg starch, cellulose, glycogen and pectin
- Pectin and cellulose contribute in the production of roughage and they are generally energy giving foods
c) Production of chemical energy storage of starch(plants) and glycogen (animals) commercial
uses e.g. manufacture of paper, textiles.
