Estimation and comparison of effective compounds (mineral contents, amino acids compositions, fatty acids distributions, protein, fat and total fiber contents) in two algae species Sirophysalis trinodis and Polycladia myrica collected from Qeshm Island were done. The samples washed up with tap water and then were dried in an oven at 40 ◦C for 3 days. The dried algae samples were pulverized and ...
Heavy metal contamination of soil, water and air has caused serious environmental hazard in the biosphere due to rapid industrialization and urbanization. A variety of metal binding ligands such as organic acids and amino acids involve in the heavy metal remediation mechanisms by plants. This paper analyses the possible role of amino acid histidine and organic acids, namely, citric, oxalic and ...
background: the interaction between serum neuron-specific enolase (nse), biogenic amino-acids and neurobehavioral function with blood lead levels in workers exposed to lead form lead-acid battery manufacturing process was not studied. objective: to evaluate serum nse and biogenic amino-acids (dopamine and serotonin) levels, and neurobehavioral performance among workers exposed to lead from lead...
background: biostimulants are amino acids and organic components, which can play main role in the plant growth and dry matter accumulation. objective: determine the influence of foliar application of active amino acids on quality and quantity yield of melissa officinalis l. methods: this study was conducted in a research farm at the institute of medicinal plants on the base of randomized comple...
در این تحقیق مطالعاتی برای بررسی و مطالعه اثر اسید آمینه های جایگاه اتصال کلسیم روی پایداری حرارتی آنزیم bmw آمیلاز-پلولاناز انجام شد. سه جهش براساس مقایسه توالی با آمیلاز های مقاوم به حرارت طراحی شد. بر اساس نتایج، جهش h58i افزایش 5/7 برابری در کارایی کاتالیتیک را نشان داد، ضمن اینکه در مورد جهش یافته s76p میزان وابستگی به کلسیم افزایش یافت و در غلظت های بالاتر کلسیم میزان پایداری این آنزیم اف...
introduction protein is an essential constituent of all tissues of animal body and has major effect on growth performance of the bird. a better understanding of the nutritional requirements of amino acids allows a more precise nutrition, offering the possibility for the formulator to optimize the requirement of at least minimum levels of crude protein by essential amino acids requirements, gene...
The sp3 C–H acetoxylation at the β-position of α,α-disubstituted α-amino acids proceeds smoothly under palladium catalysis in presence PhI(OAc)2. This reaction provides a straightforward synthetic route to non-natural β-acetoxy-α-amino acids. α-aminocyclopropanecarboxylic acid takes place via ring-opening selectively afford an acyclic γ-acetoxy-α,β-unsaturated amino acid.
