Insulin promotes synthesis of fatty acids in the liver. As discussed above, insulin is stimulatory to synthesis of glycogen in the liver. However, as glycogen accumulates to high levels (roughly 5% of liver mass), further synthesis is strongly suppressed.
Insulin and Metabolism. Insulin is a major metabolism regulating hormone secreted by Î²-cells of the islets of Langerhans of the pancreas. The major function of insulin is to counter the concerted actions of a number of hyperglycemia-generating hormones and to maintain low blood glucose levels.he metabolic functions of insulin are primarily reflective of its role in glucose and lipid homeostasis in skeletal muscle, adipose tissue, and liver. However, insulin also exerts important functions in other non-classical insulin target tissues such as the brain, pancreas, and the vascular endothelium.
