Physico-chemical-mechanical and in vitro biological properties of calcium phosphate cements with doped amorphous calcium phosphates.
Calcium phosphate cements (CPCs) are successfully used as bone substitutes in dentistry and orthopaedic applications. This study investigated the physico-chemical-mechanical properties of and in vitro biological properties (cell response) of CPCs prepared with amorphous calcium carbonate phosphate (ACCP) doped with magnesium (ACCP-Mg), zinc (ACCp-Zn) or fluoride (ACCP-F) ions. The experimental ...

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 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...
