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 اولThe Extraction of Lipids from the Red Blood Cells*
In a previous communication (1) it has been shown that lipids may be completely extracted from blood plasma or serum without heat if diluted with 20 volumes or more of alcohol-ether. The maximum cold extraction of whole blood was found to require at least 30 volumes of solvent. No values for the red blood cells were reported at that time, because it was found that heat produced apparently highe...

متن کاملExtraction of Lipids from Human Blood Plasma Using Compressed Gases
Lipids were extracted from human blood plasma using suband supercritical fluids. An extraction plant was specifically designed to allow the treatment of plasma with compressed propane, dimethyl ether (DME) and nitrous oxide (N2O) as solvents. Experiments were performed using suband supercritical gases as mild solvents to remove the lipid fraction without denaturing valuable proteins or affectin...
متن کاملEffects of various dietary fats on serum cholesterol, liver lipids and tissue pathology in rabbits.
Rabbits fed on semi-synthetic diets without added cholesterol develop hypercholesterolaemia and a form of atherosclerosis when butter (Wigand, 1959 ; Funch, Krogh & Dam, 1960) or hydrogenated fat (Wigand, 1959) is the sole dietary fat, whereas dietary vegetable oils or fat mixtures having high contents of polyenoic fatty acids increase the serum cholesterol levels only slightly and do not produ...
