BIS 103: TPP, glycogen

Question 1

TPP structure, significance

Answer 1

thiazole ring, aminopyrimidine, tail (ethyl pyrophospate)

CO2 leave plus thiazole stabiliz -> ID

Question 2

glycogen storage pros

Answer 2

1. less osmotic pressute

2, NRE - acetal - less reactive

Question 3

amylose, amylopectin, glycogen

structure, bonds, % of starch

Answer 3

1,4 1,6 30 70 0

Question 4

Glycogen Biosynthesis : has _ anchor, adds ___ of glucose

Answer 4

glycogenin- Y anchor, adds 1-8 of UDP glucose

Question 5

Glycogen biosynthesis: adds linear chains indefinitely

Answer 5

glycogen synthase, uses UDP - glucose

Question 6

Glycogen catalysis- degrades linear glycogen indefinitely

Answer 6

phosphorylase, driven by phosphoglucomutase

Question 7

glycogen catalysis - fixes branches

Answer 7

transferase - degrades 2-4

alpha-1,6-glycosidase - degrades 1 of branch
