What is Insulin? Function of Insulin

Insulin is a natural hormone controlling the level of sugar glucose in the blood. Insulin helps cell use glucose for energy. Cells cannot utilize glucose without insulin. When excess glucose produces in the bloodstream, it increases the risk of diabetes. The primary source of the fuel is insulin. Insulin let body cells take glucose from the bloodstreams. The cells may use glucose for energy production if it is required. Alternatively, the glucose is sent to the liver for preservation in the form of glycogen.

To define insulin broadly, it can be added that Insulin is a hormone, a central regulating and glucose metabolism in the body. Insulin helps cells in the liver; muscle and fat tissue take glucose from blood. It is stored in the liver and muscle as glycogen.

Insulin prevents to use fat as an energy source. When insulin is absent, body cell does not take glucose, and body resumes utilizing fat as an energy source. When Adipose Tissue transfers Lipids to the liver, it mobilizes as an energy source.

When control level of insulin fails, this failure will result diabetes mellitus. Thus, insulin is used to treat some forms of diabetes mellitus medically.

Type 1 diabetics depend on external insulin injecting subcutaneously to survive as because the system is not producing hormone no longer.

Type 2 diabetics are insulin resistant, this resistant perhaps suffer from insulin deficiency. It appears patients with Type 2 diabetes may eventually require insulin if other medications fail to control blood glucose levels at a certain extent although this is somewhat uncommon.

Insulin also influences other body functions including vascular compliance and cognition. Once insulin enters the human brain, it strengthens learning, memory and it particularly benefits verbal memory.

The functions of Insulin: Insulin regulates glucose metabolism and deals with stimulates lipogenesis, diminishes lipolysis, increasing amino acid transport into cells, modulation of transcription, altering the cell content of numerous mRNAs, growth stimulation, DNA synthesis and cell replication.

Therefore, the elaborated function of Insulin can be countering the concerted action of a number hyperglycemia generating hormones and maintaining low blood glucose levels. Because there are many hyperglycemia hormones, untreated disorders associated with insulin leading to severe hyperglycemia and shortened life span.

Moreover, the function of insulin is critical for having a healthy body. Pancreas produces insulin. Islet cells usually produce it. The pancreas behind the stomach is a vital organ. The pancreas produces all types of digestive enzymes and hormones that are designed to breakdown the food.

Insulin is considered for both a protein and a hormone. It is the regulating body to distribute the necessary amount of blood sugar requiring in each cell. When we eat, the food is converting into glucose. This is simply sugar. In addition, it is widely known as “blood sugar level”.

Insulin regulates glucose metabolism, it also stimulates lipogenesis, diminishes lipolysis, and increases amino acid transportation into cells.
