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 pancreas.
