Carbohydrate

Carbohydrate is provides body cells with the energy that they need.
Examples are:

Polysaccharide: Starch, cellulose, glycogen.
Disaccharide: Maltose, sucrose and lactose.
Monosaccharide: Galactose, fructose and glucose.

--> Monosaccharides are the simplest form of sugar and cannot be broken down any further.
--> As our body do not have cellulase, cellulose cannot be broken down, hence they will be egected from our body.

Starch is broken down into smaller pieces when we chew and digested into maltose through our salivary amylase in our mouth. Further digestion takes place in the small intestine, the jejunum.

The end product of starch is glucose and will be assimilated.

--> Excess carbohydrate in our body are turned into fats and glycogen. Glycogen is stored in livers and muscles. While fats are stored in the adipose cells. They will only be used if the carbohydrate intake is low.
