Insulin molecules, animated model. The bright lines within each molecule indicate the position of the atoms and the bonds between them. The pink skin shows the volume taken up by the electrons. Insulin is a peptide hormone formed of 51 amino acids. It is released by beta cells in the pancreas in response to increased blood sugar (glucose) levels, where it promotes the uptake of glucose by liver and fat cells. Failure of this system causes diabetes. | |
