Therefore a biological catalyst is one used within the body to speed up biological reactions). These are further categorized into three categories: lipase (the breaking down of lipids), carbohydrase (the breaking down of carbohydrates), and protease (the breaking down of proteins). Examples of these are amylase (carbohydrase), lipase (lipase) and trypsin, (protease). E.g. PROTEIN›(enzyme)›POLYPEPTIDES/PEPTIDES›(enzyme)›AMINO ACIDS What is trypsin? Trypsin is initially produced in the pancreas as typsinogen, a zymogen (inactive form), to allow metabolic control. This trypsinogen is secreted into the duodenum as pancreatic juice, where it is converted into trypsin by another enzyme secreted by the cells lining the duodenum.
