متن کاملextraction 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 اولRepellent and insecticide activity of Pelargonium x hortorum against Spodoptera littoralis (Boisd.).
Insecticide and repellent activity of an acetone extract and oil from fresh leaves of Pelargonium x hortorum (cv. Orangesonne) were evaluated against the 2nd and 4th instar larvae of Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae). The oil showed medium toxicity against the 2nd instar and low toxicity against the 4th instar larvae, while the extract showed high significant toxicity at a...
متن کاملEffect of Soybean Trypsin Inhibitor on Digestive Proteases and Growth of Larval Spodoptera Littoralis (boisd.)
Two serine proteases were identified in midgut of 4 instar of Spodoptera littoralis. A trypsin-like one (BApNAhydrolyzing) (TRYP) with a pH optimum at 11.0, and a chymotrypsin esterase-like enzyme (BTEE-hydrolyzing) (CHYMO) with optimum activity at pH 10.0. Serine protease activities were significantly (p < 0.001) inhibited in vitro by soybean trypsin inhibitor (SBI). The incorporation of diffe...
متن کاملRepellent and insecticidal activities of Melia azedarach L. against cotton leafworm, Spodoptera littoralis (Boisd.).
A crude acetone extract and oil of ripe fruits from Melia azedarach L. were evaluated against the 2nd and 4th instar larvae of Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae). Both oil and extract exhibited highly significant growth inhibition at all concentrations tested, while the oil of M. azedarach recorded higher insecticidal activity against both instars than the crude extract. GC...
