胱氨酸

The high laevorotation of L-cystine depends on a specially helical structure of its molecular.

指出了L-酸高度的左旋性是由其分子的特殊螺旋结构决定的。

Therefore,it is important to control strictly reaction conditions for removing cystine's mesoisomer and making L-cystine of high optical purity.

严格控制反应条件，分离除去内消旋酸是制取高光学纯度L-酸的重要措施。

Inhibits also some other serine and cysteine proteases like bromelain, ficin and papain.

也抑制其他的丝酸酸白，如菠萝白、无花果白瓜白。

The sulfhydryl (thiol) group (SH) of cysteine is responsible for the chemical properties of the whole GSH molecule (L-gamma-glutamyl-Lcysteinylglycine).

酸所带有的硫氢基（硫醇）决定了整个谷甘肽分子的化学性质。

Tripeptide aldehyde. Reversible competitive inhibitor of serine and cysteine proteases. Inhibits also phospholipase D and C activation in rat hepatocytes.

三肽醛。丝酸酸白可逆的竞争性抑制剂。也抑制鼠肝细胞中磷酸酯DC的活化。

Background— Cathepsin K (CatK), a potent elastinolytic and collagenolytic cysteine protease, likely participates in the evolution and destabilization of atherosclerotic plaques.

组织白K，一种强有力的溶胶原酸白，可能参与动脉粥样硬化斑块的演化及与斑块不稳定有联系。

The content of As and Sb in paints are analyzed by hydride generat io n atomic fluorescence spectrometry (HG-AFS) and L-cysteine prereduction proces s.

采用氢化物发生-原子荧光光谱法,用L-酸预还原法,对涂料中砷锑进行了分析。
