Trypsinogen Products

Trypsinogen has been shown to have certain intrinsic activity. It is usually considered, however, as the inactive precursor of trypsin which may be activated by removal of a terminal hexapeptide to yield single-chain b-trypsin. Subsequent limited autolysis produces other active forms having two or more peptide chains bound by disulfide bonds. The predominant forms are a-trypsin, having two peptide chains and b-, a single chain. Different activity and thermal stability are shown by a- and b-trypsin.
