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 اولCharacterisation of Agricultural and Agro-Industrial Residues as Raw Materials for Ethanol Production
Sugarcane bagasse, rice hulls, peanut shells, and cassava stalks are abundant lignocellulosic residues that could be considered as raw materials for ethanol production in tropical countries. The knowledge on the composition of lignocellulosic materials is important for their effective utilisation. In this work, a systematic comparison of the chemical composition of sugarcane bagasse, peanut she...
متن کاملChemical composition of caneberry (Rubus spp.) seeds and oils and their antioxidant potential.
Caneberries (Rubus spp. L.) are grown primarily throughout the Pacific Northwestern United States and Canada. Processing of caneberry fruit typically removes the seed, and the development of a value-added use of seeds could expand the market for caneberries and the profit margins for growers. An initial step toward the use of the seeds is a characterization of seed and oil. Our investigation ha...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Antioxidant agents in raw materials and processed foods.
Many food raw materials contain natural antioxidants which exert control of oxidative processes in the living cells. Among antioxidative agents are found enzymes such as superoxide dismutase, glutathione peroxidase and glucose oxidase-catalase. Among naturally occurring non-enzymic antioxidants are carotenoids, especially astaxanthin (e.g. in fish), tocopherols in oils and other phenolic compou...
