starch Flashcards
1
Q
what is the monomer of starch?
A
alpha glucose
2
Q
what are the bonds between the monomers in starch
A
1-4 glycosidic bonds in amylose
1-4 AND 1-6 in amylopectin
3
Q
what is the function of starch
A
store of glucose
4
Q
what is the location of starch
A
plants (e.g. in chloroplast)
5
Q
what is the structure of starch
A
made of 2 polymers
amylose - unbranched helix
amylopectin - branched molecule
6
Q
explain how the structure of starch leads to its function
A
- helix can compact to fit alot of glucose in a small space
- branched structure increases surfacce area for rapid hydrolyisis back to glucose
- insoluable- so wont affect water potential
