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 اولIdentification of the phenolic components of chrysanthemum flower (Chrysanthemum morifolium Ramat)
A standardised profiling method based on liquid chromatography with diode array and electrospray ionisation/mass spectrometry (LC–DAD–ESI/MS) was used to identify 46 flavonoids and 17 caffeic acid derivatives in the aqueous methanol extract of Flos chrysanthemum (Chrysanthemum morifolium Ramat) (Compositae), an important Chinese herb. Fifteen caffeoylquinic acids and 15 flavonoids were positive...
متن کاملIsolation and identification of flavonoids components from Pteris vittata L.
BACKGROUND Pteris vittata L. is rich in flavonoids which exhibit different bioactivities. In order to investigate the flavonoids components of P. vittata L., extracts of the plant were isolated by column chromatography on silica gel and Sephadex LH-20. RESULTS Four flavonoids compounds were obtained, the structures were identified as kaempferol (1), quercetin (2), kaempferol-3-O-d-glucopyrano...
متن کاملISOLATION AND IDENTIFICATION OF IRONSULPHUR OXIDZING THIOBACIULLI FROM IRAN ENVRONMENTS
Two hundred samples were taken from various sites in Iran, including coal storage areas, waste water in the Tabas and Zirab coal mines, and sulphur containing acid springs in Ramsar and Abask , and were screened for Thlobacillus ferruuxidans. During this investigation , seven strains were isolated which could oxidize sdphm , pyrite , thiosdphate and ferrous iron as the sole energy source. Macr...
متن کاملIsolation and identification of halophilicbacteria from Urmia Lake in Iran
Halophiles are in all three domains of life: Archaea, Bacteria and Eucarya. Halophilic microorganisms in addition to form major part of life biodiversity can have many biotechnological applications. The objective of this research is isolation and identification of halophilic bacteria from Urmia Lake in Iran and the study of its bacterial biodiversity. After sampling of brines from Urmia Lake fr...
