extraction 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 اولPhysico-chemical characterization of cross linked chitosan-polyacrylonitrile polymer blends
Chitin a natural polymer extracted commercially from the shells of crustaceans such as prawns, crabs, krill, insects and shrimps. Chitosan is prepared from chitin by partially deacylating its acetamido groups with a strong alkaline solution. Chitin and chitosan have a wide variety of applications such as wastewater treatment which decreases the Chemical Oxygen Demand [COD] and used in preventin...
متن کاملPhysico-chemical Properties of Sweeteners in Confections
Sugars and other sweeteners are often the main components of a confection. Besides making them sweet, they also provide bulk to the candy. However, the physico-chemical properties of the sweeteners do more than just provide bulk. The physical characteristics of a candy, which include consistency, chewy or stretchy characteristics, melt-in-the-mouth behavior, flavor release, and many other prope...
متن کاملPhysico-chemical properties of lactic dehydrogenase.
Although the mechanism of the enzymatic reaction catalyzed by lactic dehydrogenase has been investigated by several workers, little work has been reported on the physical chemistry of this protein. In particular, a precise value for the molecular weight has not been reported. Meister (1) has estimated the molecular weight to be of the order of 100,000 to 150,000. Neilands (2) has reported a val...
