polysaccharides

Question 1

structure and function of starch

Answer 1

amylose + amylopectin
insoluble so won’t affect water potential
amylopectin is more branched(1,6+1,4)
stores glucose in plants

Question 2

structure and function of cellulose

Answer 2

beta- glucose
long straight chains with many H bonds between - forms fibrils
1,4 glycosidic bonds- glucose rates 180 degrees each time

Question 3

structure of glycogen

Answer 3

alpha glucose
1,4 + 1,6 glycosidic bonds
most branched
store of glucose in animals
