- Starch, Glycogen, Cellulose
- Starch
- Polysaccharide found in many parts of a plant
- Energy source
- Chains of a-glucose linked by glycosidic bonds
- Branched or unbranched- acted on by enzymes, energy released quicker
- Coiled, compact- can store lots in small space
- Insoluble, not drawn in by osmosis
- Large/insoluble- does not diffuse out of cells
- Glycogen
- Found in animals
- Short chains
- Highly branched- released quicker. Important for animals as they need more energy quicker.
- Compact, lots stored in small space
- Insoluble- does not diffuse out of cells/not drawn in by osmosis
- Cellulose
- Monomers of b- glucose
- Straight-unbranched chains
- Chains run parallel to one another, cross linked by hydrogen bonds- add collective strength
- Chains grouped to form microfibrils- in turn grouped to form fibres, provide more strength.
- Starch
