The amino acid sequence of human typsin converted to music
Trypsin is a protein found in our digestive tract that chops up the protein we eat in our diet. Trypsin is made in the pancreas, along with several other proteins, which work to digest our food (carbohydrates, proteins, and fats), and alkalis, which neutralise the strong acid found in the stomach. Trypsin is an example of an enzyme, a protein that makes a reaction happen (a biological catalyst).
If Trypsin breaks-up proteins, why doesn't it break-up the pancreas, where it is made? Trypsin is made as an inactive form, called Trypsinogen. Cells in the duodenum make another protein called Enteropeptidase, which cuts Trypsinogen at a specific location, yielding the active form of the protein. In fact, the activated Trypsin can then activate more Trypsin, and other digestive proteins. Therefore, we don't only need Trypsin to help digest out food, but also to coordinate the activation of all of our food-digesting proteins.
