Insulin is a hypoglycemic hormone secreted by pancreatic islet β cells, and insulin is the only hypoglycemic hormone in the body. The role of insulin in the human body is mainly the following two points:

1.Regulates blood sugar, when the blood sugar concentration increases, it will promote insulin secretion, insulin can promote the uptake and utilization of glucose, promote the conversion of glucose into glycogen, thereby lowering blood sugar. When the blood glucose concentration decreases, it will inhibit the secretion of insulin, inhibit the uptake and utilization of glucose, and convert the stored glycogen into glucose to maintain the blood glucose concentration, so blood sugar is a dynamic balance between various glycemic hormones and insulin. Diabetes occurs when insulin is insufficient.

2. Insulin has a nootropic effect, which can promote the synthesis of proteins and fats, and inhibit the breakdown of proteins and fats. Therefore, insulin is a nootropic hormone that can promote the synthesis of protein, fat and glycogen at the same time, and exert a powerful hypoglycemic effect.
