Isolation and Characterization of Trypsin Inhibitors (Kunitz Soybean Trypsin Inhibitor, Bowman-birk Inhibitor) in Soybean
Soybean (Glycine max (L.) Merr.) has emerged as one of the most economical and nutritious foods. Kunitz Soybean Trypsin Inhibitor (KSTI) and Bowman -Birk Inhibitor (BBI) are the two major trypsin inhibitors in soybeans. The ingested soybean trypsin inhibitors cause growth depression as demonstrated in different animal species and human. The main part of the present study was devoted to isolatio...
متن کاملIsolation from Beef Pancreas of Crystalline Trypsinogen, Trypsin, a Trypsin Inhibitor, and an Inhibitor-trypsin Compound
Methods are described for the isolation and crystallization of trypsinogen, trypsin, a substance which inhibits trypsin, and an inhibitor-trypsin compound. Analyses and some of the properties of these compounds are given.
متن کاملIsolation of a Crystalline Protein Compound of Trypsin and of Soybean Trypsin-inhibitor
A crystalline protein compound has been isolated from a solution containing crystalline trypsin and crystalline soybean inhibitor. The protein consists of about equal weights of trypsin and of the inhibitor. Denaturation by heat or by alkali resolves the compound into its components.
متن کاملDetermination of trypsin inhibitor in blood plasma.
In 1922 Hussey and Northrop (1) found that trypsin and blood trypsin inhibitor formed an inactive but dissociable compound. Graphically the relationship was represented by a curve. Hussey and Northrop apparently used water as a diluent for plasma, since additions of the equivalent amounts of water, instead of the inhibitor, are indicated for the control tubes. Recently Shulman (2) used M/30 pho...
متن کاملCalorimetry of some trypsin-trypsin inhibitor reactions.
The heats of reaction of trypsin with soybean (Kunitz), ovomucoid, and lima bean inhibitors have been measured at pH 5.0 and 10’ and 25”. All the reactions were endothermic, with AH ranging from 8.6 Cal per mole for the lima bean inhibitor to 15.3 Cal per mole for the soybean inhibitor. Equilibrium constants for the association were calculated from the dependence of residual tryptic activity up...
