chapter 25: glycogen synthesis

UDP-glucose

activated carrier of glucose in glycogen synthesis

UDP-glucose pyrophosphorylase

UDP-glucose is synthesized from G1P and UTP in a reaction catalyzed by

Glycogen synthase

enzyme that helps form α-1,4-glycosidic bonds in glycogen synthesis

glycogenin

CORE primer is made by enzyme _________ and starts glycogen synthesis

branching enzyme

removes an oligosaccharide of approximately seven residues from the nonreducing end and creates an internal α-1,6 linkage

a form

active non-phosphorylated ________ of glycogen synthase

b form

inactive phosphorylated _________ of glycogen synthase

glycogen synthase kinase

phosphorylates glycogen synthase to transform it into inactive b form.
