Insulin is a peptide hormone produced by beta cells in the pancreas. It regulates the metabolism of carbohydrates and fats; in addition, it stores fat to be used for energy later. When you eat, your blood sugar increases, which causes insulin to be released.
Insulin, which is both a hormone and a protein, is a balled-up string of chemicals called amino acids. There are 20 common amino acids, such as tryptophan, that combine end to end to make proteins. Like the letters in a word, the order and number of amino acids in the protein are what define it.
