WebGlycogen synthase is the rate-limiting enzyme of glycogen synthesis and forms the α-1,4 glycosidic bond. It is stimulated by G6P and insulin and is inhibited by epinephrine and glucagon through a protein kinase casade that phosphorylates and inactivates the enzyme. WebExamples of glycosidic linkages = starch, glycogen, nucleotide. Hydrolysis of the glycosidic bond has the same mechanism as hydrolysis of the acetal bond. glycoside + H 2 O + catalyst → hydrolysis. Catalysts include: …
