- Carbohydrates
- Amylose
- structure
- function
- insoluble. dont affect water potential
- large molecule, cant leave cell
- Cellulose
- function
- long and straight chains. linked together by many H bonds to form fibrils. provide strength to cell wall
- can resist osmotic pressure. bond difficult to break
- microfibril-> fibril
- OH group point outwards
- microfibril-> fibril
- H bonds collectively strong
- can resist osmotic pressure. bond difficult to break
- long and straight chains. linked together by many H bonds to form fibrils. provide strength to cell wall
- structure
- B glucose
- beta 1-4 linkages
- inverted alternate molecules
- straight unbranched chains
- condensation bonds
- B glucose
- function
- Amylopectin
- structure
- repeating units of alpha 1-4 glycosidic bonds
- 1- 6 linkage every 30 monomers
- function
- branched- broken down to release energy for glucose
- structure
- Glycogen
- structure to function
- highly branched. glucose broken down through resp at faster rate
- 1-6 linkage come off main chain every 4 glucose mols
- repeating units of 1-4 alpha glycosidic bond
- compact- alpha glucose. lots stored in small space
- insoluble- not affect water potential or leave cells
- highly branched. glucose broken down through resp at faster rate
- structure to function
- starch- made up of alpha glucose
- difference between starch and cellulose
- position of hydrogen and hydroxyl groups on carbon atom 1 inverted
- starch contains alpha glucose. helical
- no fibrils/ H bonds between molecules
- starch similar to cellulsoe
- polysaccharides
- contain CHO
- glycosidic bonds. 1- 4 linls
