This gallery shows some different ways of illustrating insulin and includes pictures relating to the pancreas and diabetes
Insulin is a protein of 51 amino acids. It is a protein hormone that signals how much glucose is in the blood, and it is made in the pancreas. People with type 1 diabetes make too little or no insulin in their bodies, so they must inject a synthetic version of the hormone to compensate.
