Trypsin inhibitors are found in a variety of sources, such as soybean, human
plasma, lima bean, and bovine pancreas. Soybean trypsin inhibitor will inhibit
trypsin mole for mole and will also inhibit chymotrypsinogen to a lesser extent.
Trypsin inhibitor from soybean has a molecular weight of 24,000 and is composed
of a single polypeptide chain, which is crosslinked by two disulfide bridges.
Trypsin inhibitor is used for the treatment of hyperactive conditions of the
