insulin insulin. n. 1. (Biology) a protein hormone, secreted in the pancreas by the islets of Langerhans, that controls the concentration of glucose in the blood. Insulin deficiency results in diabetes mellitus. [C20: from New Latin insula islet (of the pancreas) + -in]. (ˈɪn sə lɪn, ˈɪns yə-). n.

Insulin Insulin is produced in the pancreas and released when any of several stimuli are detected. These stimuli include ingested protein and glucose in the blood produced from digested food. Carbohydrates can be polymers of simple sugars or the simple sugars themselves.atients with type 1 diabetes depend on external insulin (most commonly injected subcutaneously) for their survival because the hormone is no longer produced internally. Patients with type 2 diabetes are often insulin resistant and, because of such resistance, may suffer from a relative insulin deficiency.

insulin : a protein pancreatic hormone secreted by the beta cells of the islets of Langerhans that is essential especially for the metabolism of carbohydrates and the regulation of glucose levels in the blood and that when insufficiently produced results in diabetes mellitus. See insulin defined for English-language learners.

What is Insulin? Insulin is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia). The cells in your body need sugar for energy. However, sugar cannot go into most of your cells directly. After you eat food and your blood sugar level rises, cells in your pancreas (known as beta cells) are signaled to release insulin into your bloodstream.

Insulin Not to be confused with Inulin. Insulin (from the Latin, insula meaning island) is a peptide hormone produced by beta cells of the pancreatic islets. It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of, especially, glucose from the blood into fat, liver and skeletal muscle cells.

All About Insulin Insulin is a natural hormone which controls the level of the sugar glucose in the blood. Insulin allows cells to use glucose for energy. Cells cannot utilize glucose without insulin. Excess glucose builds up in the bloodstream, increasing the risk of diabetes. Glucose is the body's primary source of fuel. Insulin enables the body cells to take glucose from the bloodstream.

Alternative names for diabetes mellitus Insulin is a hormone produced by the beta cells within the pancreas in response to the intake of food. The role of insulin is to lower blood sugar (glucose) levels by allowing cells in the muscle, liver and fat to take up sugar from the bloodstream that has been absorbed from food and store it away as energy.

Neurotransmitter Fluoxetine is a selective serotonin re-uptake inhibitor (SSRI), which blocks re-uptake of serotonin by the presynaptic cell which increases the amount of serotonin present at the synapse and furthermore allows it to remain there longer, providing potential for the effect of naturally released serotonin.

- Biology Dictionary. Definition: A type of lipid that consists of glycerol with three fatty acids bound to it. A high triglyceride count in a person's blood is a symptom of diseases such as diabetes. The body needs insulin to remove excess triglycerides from the blood.

- Insulin is a hormone produced by the pancreas that controls glucose levels in blood by reducing the amount of glucose made by the liver and by increasing the removal of glucose from the blood by muscle and fat tissues. As a result, insulin causes blood glucose levels fall.

What is insulin? Insulin is a hormone made by an organ located behind the stomach called the pancreas. Here, insulin is released into the bloodstream by specialised cells called beta-cells found in areas of the pancreas called islets of Langerhans (the term insulin comes from the Latin insula meaning island). Insulin can also be given as a medicine for patients with diabetes because they do not make enough of their own.

Physiologic Effects of Insulin Insulin is a key player in the control of intermediary metabolism, and the big picture is that it organizes the use of fuels for either storage or oxidation. Through these activities, insulin has profound effects on both carbohydrate and lipid metabolism, and significant influences on protein and mineral metabolism.

Insulin Synthesis and Secretion Insulin is a rather small protein, with a molecular weight of about 6000 Daltons. It is composed of two chains held together by disulfide bonds. The figure to the right shows a molecular model of bovine insulin, with the A chain colored blue and the larger B chain green. You can get a better appreciation for the structure of insulin by manipulating such a model yourself.
