Carbohydrates- Polysaccharides Flashcards
(9 cards)
1
Q
Starch
A
Stores excess energy in plants that can be hydrolysed into glucose
2
Q
Amylose
A
- Long unbranched chain of alpha glucose joined by 1-4 glycosidic bonds
- This causes the chain to coil into a helix and makes a compact structure
3
Q
Amylopectin
A
- Long branched structure of alpha glucose with 1-4 and 1-6 glycosidic bonds
- Side branches allow enzymes to hydrolyse alpha-glucose monomers easily
4
Q
Features of starch
A
- Insoluble
- Large
- Many side branches
- Coiled
5
Q
Glycogen
A
- Made up of many alpha-glucose monomers joined via 1-4 and 1-6 glycosidic bonds to form highly branched chains.
6
Q
Features of glycogen
A
- Insoluble
- Compact
- More highly branched
- Large
7
Q
Cellulose
A
- Long, straight unbranched chain made up of beta-glucose molecules that are inverted 180 degrees
8
Q
Microfibrils
A
Cross linked cellulose chains
9
Q
Adaptations of cellulose
A
- Long, straight and unbranched
- Hydrogen bonds
- Microfibrils
