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 اولAnalysis of beta-sitosterol in seeds and nuts using pressurized liquid extraction and liquid chromatography.
Pressurized liquid extraction (PLE) has been used for the extraction of beta-sitosterol from food samples. In the present work, extractions were performed by mixing ground samples with Hydromatrix celite with methanol at 50 degrees C and 110 bar, using two 5-min cycles. After extraction, beta-sitosterol was analyzed directly by liquid chromatography with diode array detection. The extraction re...

متن کاملExtraction, Purification, and Characterization of Trypsin Obtained from the Digestive System of Yellowfin Seabream (Acanthopagrus latus)
The development of the marine aquaculture industry has led to the generation of significant amounts of fish wastes. Marine farm wastes exert adverse effects on the surrounding area of the cages. On the other hand, wastes of fish and other aquatic animals are regarded as major sources of valuable natural bioactive compounds, including enzymes, proteins, bioactive peptides, oil, amino acids, coll...
