The hormone is released in response to acute stress and low levels of glucose in the blood. Glycogen synthase is an enzyme that is responsible in glycogen synthesis. It is activated by glucose 6-phosphate (G6P), and inhibited by glycogen synthase kinases (GSK3). Those two mechanisms play an important role in glycogen metabolism.

3). Activation of glycogen synthase by 50 m m LiCl ranged from 43 to 103% of that in response to 100 n m insulin (mean, 61.4 ± 8.2%;n = 7 experiments), and the combination of LiCl and 1 n m insulin gave a supramaximal response (Fig.3 A).

It is a glycosyltransferase (EC 2.4.1.11) that catalyses the reaction of UDP-glucose and (1,4-α-D-glucosyl) n to yield UDP and (1,4-α-D-glucosyl) n+1 Glycogen synthase, as discussed earlier, catalyzes the rate-limiting step in glycogen synthesis in the liver and in skeletal muscle, namely, the transfer of glucose monomers from UDP-glucose to the terminal branch of the growing glycogen chain via the formation of α (1→4) glycosidic bonds.79 Several glycogen synthase isoforms exist – one specific to skeletal muscle (encoded by GYS1), and one specific to the liver (encoded by GYS2). Glycogen Synthase (GS) is an enzyme present in liver and muscle cells that catalyses the production of glycogen. It catalyses a condensation reaction between UDP-glucose and glycogen (n-residues) to form glycogen (n+1 residues) and UDP, elongating the glycogen polymer. Glycogen synthase is one of many enzymes found within the human body. An enzyme is a type of protein which works to catalyze, or speed up, various chemical reactions within the body. Glycogen synthase helps to convert glucose, or blood sugar, into glycogen. Glucose is a simple sugar used by the cells of the body to create energy.

Muscle-cell glycogen is chemically identical to liver glycogen.

On the other hand, in the isolated mouse soleus muscle, glucose enhanced the activation of glycogen synthase by in-sulin (17).

Glycogenin, a protein, autocatalyzes the synthesis of a glycogen primer, covalently attached to itself, which glycogen synthase extends. Therefore, the number of molecules of glycogenin present determines the number of glycogen molecules synthesized. Glycogen synthase must always be in contact with glycogenin to be active.

The outer two rings each contain seven α subunits whose function is to maintain The ATP synthase in mitochondria uses the flow of protons in an analogous way. After glycogen stores are full, sugar that arrives in the liver is converted into 

On the other hand, in the isolated mouse soleus muscle, glucose enhanced the activation of glycogen synthase by in-sulin (17). In transgenic mice modified in the glu-cose transporters it has been demonstrated that glucose transport in muscle is essential for the acti-vation of glycogen synthase (18). In this review, we highlight the links between glycogen synthase kinase-3 (GSK-3) activity and tau function in normal and diseased brain. Figure 1 Tau isoforms in the human CNS and identified GSK-3 phosphorylation sites. Glycogen synthase kinase-3β (GSK-3β) is a ubiquitously expressed constitutively active serine/threonine kinase that phosphorylates cellular substrates and thereby regulates a wide variety of cellular functions, including development, metabolism, gene transcription, protein translation, cytoskeletal organization, cell cycle regulation, and apoptosis.
