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.
