Question

Explain. 19. Meat and potatoes. Compare the structures of glycogen and starch.

Answer 1

there are some similarities and some differences in the structures of glycogen and starch. where starch is found in plants, glycogen is related to animals both are made up of glucose units but still are different due to different arrangements of these glucose units.

Page Aus19 Starch glycogen. have x-D-glucose have x-D-glucose glucose units are linked together by x-1,4-glycosidic and x-1,6-glycosidic linkages. same linkages like as in starch X-1,4-glycosidic X-1,6-glycosidic the similarities between These them were till now 0 2-1,4-glycosidic dinkage @x-1,6-glycobieliz linkage These are the two types of linkages Type 1 I long Type in the is responsible for single chain. is responsible for the branching structure.

Da Page The main difference between Starch and glycogen is amount of branching. the An starch usually x-1,6-glycosidic dinkage / branching occurs at every 25-30 glucose units. But in glycogen this branching occurs after every 8-12 glucose units. Thus there is extensive branching- in glycogen where as in starch branching is not eat that extent. Starch. glycogen.
