6 Starch and glycogen are similar because they:
A. both have many peptide bonds
B. both have many a1,4 glycosidic linkages
C. both are used primarily as a storage mechanism for glucose
D. both bind well to hydrophobic compounds
E. B & C
Homework Answers
The correct answer is option E. Starch and glycogen are storage form of glucose. Not only glucose all main carbohydrates are stored in the form of starch and glycogen. Both have alpha 1,4 glycosidic linkages as well as 1,6 glycosidic linkages. The difference is that starch is the main source of carbohydrates in plants where as glycogen is the main carbohydrate source for fungi and animals

A patient was seen by a gastrointestinal specialist and diagnosed with a glycogen storage disease. A liver biopsy showed that the patient was producing very little glycogen, the molecules were relatively small, and they only had a(1,4) glycosidic linkages. Blood and liver glucose concentrations were within normal ranges. What enzyme is likely affected in this disease? a. glycogen synthase b. glycogen phosphorylate c. branching enzyme d. debranching enzyme e. hexokinase
