Insulin is a polypeptide hormone, which can lower blood glucose in the body by promoting the synthesis of glycogen, inhibiting the breakdown of glycogen and increasing the utilization of glucose.
After insulin enters the body, it can combine with insulin receptor to cause a series of reactions in the body and produce the effect of lowering blood sugar.
1. Promote glycogen synthesis. Insulin can promote glucose metabolism, accelerate the body’s synthesis of glycogen and storage, reduce blood sugar.
2. Inhibit glycogen decomposition. It can inhibit the decomposition of glycogen in the body, and can inhibit the conversion of fat, protein and other substances into blood sugar.
3. Increase glucose utilization. Insulin can increase the utilization of glucose by promoting the synthesis of fats and proteins, thus lowering blood sugar.
As the only hormone in the body that can lower blood sugar, insulin plays a key role in controlling blood sugar, and diabetic patients should use insulin to lower blood sugar under the guidance of doctors.
