Storage Polysaccharide

Polysaccharides are Monosaccharides linked together in long chains.
Starch is the pricipal food storage form found in most plants (potato = starch from leaves.)
Occurs in amylose and amylopectin
Glycogen
- Principal storage form in higher animals
- Branches every 8 to 10 glycose units
- Stored primarily in liver and muscle units
  - In humans, when an excess of glucose is present in the bloodstream, glycogen is formed in the liver.
  - When there is a lack of glucose, glycogen is broken up.
- Formation of polysaccharides requires energy.
- When cell needs energy, polysaccharides can be hydrolized (broken up) and resulting monosaccharides can be oxidized, resulting in an energy release.
