说明

General description

L-半胱氨酸盐酸盐常称为半胱氨酸HCl，由于其多功能特性，是生物化学研究的关键试剂。该化合物来源于天然氨基酸L-半胱氨酸，它在氧化还原反应、蛋白质结构、细胞培养和抗氧化活性中起关键作用。半胱氨酸HCl在氧化还原反应中可用作还原剂和亲核试剂。此外，它还是强效细胞抗氧化剂谷胱甘肽的前体。其重要性还体现在蛋白结构中，它有助于形成可稳定蛋白质结构的二硫键。在细胞培养应用，半胱氨酸HCl还有助于细胞生长和存活。其广泛应用涵盖多种生物化学研究领域，包括氧化还原生物学、蛋白质生物化学、细胞生物学和抗氧化剂研究。

Application

L-半胱氨酸盐酸盐一水物用作酵母脱落培养基的成分，用于培养酵母。它也被用作强化梭菌鉴别肉汤(DRCM)的一个成分，用于分离梭菌。

Biochem/physiol Actions

半胱氨酸(Cys)是一种含硫氨基酸，可调节新陈代谢，促进生长、繁殖和免疫。它提供蛋白质中的二硫键并参与硫的转运。半胱氨酸参与作为信号分子的硫化氢的形成过程。Cys残基存在于多种酶的催化位点。

NMDA谷氨酸能受体拮抗剂。
