Colipase is a cofactor of pancreatic lipase. It allows the lipase to anchor itself to the lipid-water interface. Without colipase the enzyme is washed off by bile salts, which have an inhibitory effect on the lipase. Enterostatin has a biological activity as a satiety signal. Forms a 1:1 stoichiometric complex with pancreatic lipase. Belongs to the colipase family.
