Isolation and properties of hyaluronic acid from bovine heart valves.
1. A soluble extract of bovine heart valves was obtained after the tissue had been pulverized at liquid-nitrogen temperatures in a mill. 2. Hyaluronic acid was isolated from the crude extract by sedimentation equilibrium in a caesium chloride density gradient (Franek & Dunstone, 1966). 3. Analysis of the product indicated that it contained 15% of protein and the molar ratio of glucuronic acid t...

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 اولOn the polylactose nature of chondroitin and keratan sulphates.
The recognition that keratan and chondroitin sulphates are based on the same polylactose backbone simplifies the study of heteroduplex formation between them, suggests insights into structure-function relationships in tissues, and permits new definitions of the linkage regions.
متن کاملIsolation and properties of immune lactoglobulins from bovine whey.
It has already been reported that the principal protein of bovine colostrum is immune lactoglobulin, and a procedure has been described for the isolation of this protein (1). While the immune properties of colostrum have been generally recognized, it is widely believed that this is a specific quality of colostrum, and that immune properties are absent from the later milk or are present only in ...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
