Synthesis of ring labeled [ 1 ’ - 14 C ] - L - tyrosine Ryszard
The enzyme β-tyrosinase (tyrosine phenol lyase, EC 4.1.99.2) has been shown [8, 9, 15] to catalyze the decomposition of L-Tyr to phenol, pyruvate and ammonia. Under some conditions, this enzyme also participates in the reverse reaction leading to formation [10, 12, 13] of L-Tyr (Scheme 1). As a metabolism of L-Tyr is an important process of the living cells, the mechanism of the above reaction ...

متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Synthesis of D- and L-selenomethionine double-labeled with deuterium and selenium-82.
The synthesis of D- and L-selenomethionine labeled with ⁸²Se and three deuteriums at Se-methyl group (D- and L-[²H₃, ⁸²Se]selenomethionine) was described. D- And L-[²H₃, ⁸²Se]selenomethionine were prepared by condensation of (R)- and (S)-2-amino-4-bromobutylic acid with lithium [²H₃, ⁸²Se]methaneselenolate, which was prepared from metal (82)Se and [²H₃]methyl iodide. The optical purities of D- ...
