Insulin

A hormone that is secreted by the pancreas and controls the amount of glucose in the blood. Glucose is the body’s main source of energy. Insulin stimulates cells to absorb and use glucose for energy. Without insulin, cells starve for energy and glucose builds up in the blood (hyperglycemia). Insulin also refers to the laboratory-made drug.
