Glycogen - the storage form of glucose - is a ramified polysaccharide formed by alpha1-4 linked glucose units branching at alpha1-6 bonds. Upon uptake into the cell, glucose is rapidly phosphorylated to G6P, a key molecule at the intersection of several pathways of glucose metabolism. In the glycogen biosynthetic pathway, G6P is converted to G1P via the reversible reaction carried out by phosphoglucomutases (Pgm). UDP-glucose pyrophosphorylase (Ugp2) catalyzes the formation of UDP-glucose
