Significance of Soya Trypsin Inhibitors
Although recent evidence clearly indicates that trypsin inhibitors (TO and low protein digestibility are the major factors responsible for the pancreatic hypertrophic and growth inhibitory effects of raw soybeans, there was uncertainty regarding the biological threshold level of TI at which these biological effects occur. To obtain such data, dehulled defatted flakes (10% dietary protein) conta...
متن کاملOrganocatalytic mannich-type reactions of trifluoroethyl thioesters.
Direct organocatalytic Mannich-type reactions of thioesters provide for the expedient and diastereoselective synthesis of protected beta-amino acids. A variety of thioesters were found to be reactive with different imines under mild conditions to provide beta-amino acids in good yields. This chemistry was extended to a diastereo- and enantioselective variant.
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولCompetition among trypsin inhibitors.
The experiments presented in this paper were designed to elucidate the kinetics of action of three protein inhibitors (from pancreas, soy bean, and egg white) on trypsin, and to discover how the inhibition by these substances was related to the action of diisopropyl fluorophosphate (DFP), mercuric chloride, and calcium salts on trypsin. The most, detailed work on the protein inhibitors of tryps...
