Understanding and definition of Insulin. Insulin is a hormone that is produced by the organ that serves to regulate the metabolism of carbohydrates, fats, and proteins. The levels of insulin in the body can be an indicator of disease symptoms of diabetes mellitus. Because of the failure of the body to produce insulin or inadequate insulin levels is the main cause of the disease reaching sweet or diabetes mellitus.
Insulin is a hormone type polypeptide. The organs responsible for the production of insulin in the pancreas gland. The cells that make insulin in the pancreas gland hormone called beta cells that are part of a group of cells called Islet of Langerhans or with the islands of Langerhans. Because it is a hormone produced by cells in it called Insulin that is derived from the Latin word insula meaning island.
Insulin production is affected by the intake of the nutrients we eat. Especially glucose levels found in the blood. Normally, the higher the levels of glucose in the blood, then more and more insulin in the pancreas organ by disconnect to bring blood sugar into the cells so it can be used as fuel or stored as fat in excess. High insulin levels will lead to overweight or obesity. While overweight or obese themselves will cause insulin resistance that will eventually culminate in the incidence of diabetes mellitus. From there we can see a little picture that the advantages and disadvantages of insulin will eventually become the primary cause of diabetes. Then how is the mechanism of action of insulin in the body so that the condition of shortage and excess insulin can occur?
Insulin is a hormone receptor Act on receptors from cells that trigger biochemical reaction complex that controls blood sugar. Cells that are targeted by insulin are fat cells (adipocytes), muscle cells (myocytes striated), and liver cells (hepatocytes). Fat and protein is an alternative energy source for the body. If carbohydrates are not able to meet the needs of calories, the body will take it from deposits of protein and fat body. That's why a man who suffered from diabetes usually skinny bodied dry. Because of the lack of insulin causes a lack of work an effective the cover of the fuel the body as FAT or protein.
There are at least two types of performance-related abnormalities of insulin deficiency, namely Insulin and insulin resistance. Though equally could be a cause of kissing is sweet, but the mechanism of onset is somewhat different. As a saying about ' another path to Rome '. If Rome is the disease of diabetes mellitus, insulin deficiency and then insulin resistance are two roads lead to diabetes.
Insulin deficiency occurs when the pancreas organ fail or experience interference while producing the hormone insulin, so that insulin was not formed or simply applied is very small. Whereas insulin resistance is the phenomenon in which the body produces too much insulin to be saturated at a level so that it can cause damage to the receptor-receptor cells that can trigger biochemical reactions of complex who can control the sugar levels in the blood. Insulin resistance usually occurs when a person suffering from overweight or obese. This condition can cause the performance of insulin is not effective. The effect is weight loss in a dramatic and then continue on with the appearance of the common symptoms of diabetes.
