- Polysaccharides
- Starch
- Structure
- Insoluble, forms starch granules
- Mixture of amylose and amylopectin
- Amylose - chain of glucose, helix
- Amylopectin - branches give an open structure, broken down quicker
- Broken down by amylase into maltose
- a glucose
- Flexible
- Function
- Plant pollysaccharide storage
- Structure
- Cellulose
- Function
- Only found in plants, mainly cell walls
- Structure
- Isomer of glucose
- B glucose
- Rigid
- Straight
- Broken down by cellulose in bacteria
- Beta glucose
- different position of hydroxyl group
- Alternate glucose molecules are inverted
- Linked chains - cellulose microfibrils
- Strength to plants
- Function
- Glycogen
- Structure
- Highly branched, mobilised quickly
- Linear chains of glucose
- Broken down by glycogen phosphorylase
- a glucose
- Flexible
- Function
- Animal polysaccharide storage, mainly in muscle and liver.
- Quick sauce of energy
- Structure
- Starch
