巯基

Thiols are also active in the catalytic sites of enzymes,and play important roles in metabolic pathways.

细胞内巯基化合物(包括半胱氨酸、高半胱氨酸和还原型谷胱甘肽等)在维持生命体系的氧化还原动态平衡方面起着重要的作用，它们是与酶活性有关的最具有反应性的官能团，并且在酶代谢过程中起着重要的作用。

Intracellular thiols such as glutathione,cysteine,and homocysteine play a crucial role in maintaining biological redox homeostasis.

巯基化合物是生物体中许多蛋白质和小分子的重要组成部分，在细胞抗氧化系统中具有重要的作用。

The levels of certain thiols,such as homocysteine,have been linked to a number of diseases,including cancer,Alzheimer's, cardiovascular disease and so on.
