Food Chemical Studies on Soybean Proteins

Physical and chemical properties of soybean proteins.

Studies on the inhibition of pancreatic and microbial lipases by soybean proteins.

A protein, molecular weight 70,000 that inhibits pancreatic lipase has been isolated from soybean seeds. Inhibition is not reversed by colipase unless bile salts are added to the assay system. Inhibitory properties of the purified protein are very similar to those of serum albumin or alpha-lactoglobulin. It has been confirmed that, during intestinal lipolysis of dietary fats, bile salts play an...

Inactivation studies on the soybean hemagglutinin.

Previous studies from this laboratory have described some of the physical (l), chemical (2, 3), and immunological (4) properties of the soybean hemagglutinin (SBH)l which is responsible in part for the poor nutritive value of unheated soybean meal (5). Since the destruction of this protein has obvious practical implications in the field of animal nutrition, a comprehensive study has been made o...

Studies on Platelet Proteins

T HE IMPORTANCE of blood platelets in hemostasis is now well established.’ Many of the physiologic properties of platelets suggest the presence of a contractile protein and Bettex-Galland and L#{252}scher ( 1961 ) succeeded in isolating such a contractile protein, thrombosthenin, and studied some of its properties.24 Grette ( 1962 ) confirmed the presence of this protein in pig platelets.5 Sinc...
