Purification of Rennin from Commercial Rennin Extract: Properties of Purified Product

The purification and crystallization of rennin.

The Effect of Rennin upon Casein

The properties of the paracasein and casein preparations studied are compared in Table VI. See PDF for Structure I. Casein retains its characteristic solubility in NaOH: (1) after being exposed to a high degree of alkalinity during its preparation, (2) when recovered from partially hydrolyzed solutions in NaOH, and (3) after being kept for a prolonged time at the isoelectric point at 5 degrees ...

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 ...

The Action of Rennin on Casein

In order to determine if the change from casein to paracasein results in the cleavage of any of the elements contained in the casein molecule, it is imperative that pure casein be used as a standard of comparison, and that the rennin activity be positively differentiated from any further proteolyt,ic activity of the enzyme under consideration; for it is quite evident that “Rennin action is prob...

The Action of Rennin on Casein

The changes produced by the action of rennin in milk and solutions of casein have been the subject of many investigations. Fremy’ was probably the first to give an explanation of this phenomenon. He believed the power to coagulate milk possessed by an extract of the mucous lining of a calf’s stomach to be due to the presence of an enzyme which converted some of the lactose of the milk into lact...
