释义 Definition

thiols(硫醇;巯基化合物):一类含有SH(巯基/硫氢基)官能团的有机化合物,常写作 RSH。在生物化学中与蛋白质中的半胱氨酸、抗氧化与二硫键形成等过程密切相关。(也常被称作 mercaptans。)

发音 Pronunciation (IPA)

/θa.lz/(复数);单数 thiol:/θa.l/

例句 Examples

Thiols often have a strong smell.
硫醇通常有很强的气味。

In proteins, thiols on cysteine residues can be oxidized to form disulfide bonds that stabilize the folded structure.
在蛋白质中,半胱氨酸残基上的巯基(硫醇基)可以被氧化形成二硫键,从而稳定折叠后的结构。

词源 Etymology

thiol 来自希腊语 theion(“硫”)+ 化学命名后缀 -ol(常用于表示含羟基的醇类,后来也用于类似命名体系中),用于指代含硫的“类醇”官能团 SH
