Photograph of Insulin (Novolin, Humulin) under the microscope.

Insulin is a peptide hormone produced by the pancreas that controls the amount and adsorption of glucose in the bloodstream. When the body malfunctions and does not produce enough insulin, a condition known as diabetes mellitus arises and patients must be treated with insulin from an external source to insure normal metabolism. Insulin is manufactured from beef or pork pancreas glands, and is available as an injection for diabetes patients.
