- 1Structure of starchMonomer: Alpha-Glucose
Wound into tight helix; Compact+more stored in a given volume.
Insoluble; Doesn't effect water potential
Large; Will not diffuse out of cells
Hydrolysed to alpha-glucose; Easily transported+used in respiration
Branched form has many ends; Enzymes (amylase) can break down all at same time= Monomers quickly released.
- 2Structure of CelluloseMonomer: Beta-Glucose
Straight, unbranched chains that run parallel to each other.
Hydrogen bonds form between chains= Cross-linkages
Bonds are very weak alone but amount of them produces strong MICROFIBRIL which are arranged into FIBRES (More strength) and make up the cell wall.
- 3Structure of GlycogenMonomer: Alpha-Glucose
More branched than starch + Shorter= Quicker Breakdown
Compact= Store a lot in a little space
Insoluble= No effect on w.p.
Large= Will not diffuse out of cell
Hydrolysed to a-glucose= Easy to transport + use for respiration
