硫醇 Thiol

（重定向自Thiols）

The catalytic cycle for ribonucleotide reductase, demonstrating the role of thiyl radicals in producing the genetic machinery of life.

硫醇是包含巯基官能团（-SH）的一类非芳香化合物。是一类有机硫化合物。可以看成醇中的氧被硫替换

硫醇中，硫原子为不等性sp杂化态，两个单电子占据的sp杂化轨道分别与烃基碳和氢形成σ键，还有两对孤对电子占据另外的两个sp杂化轨道。由于硫的3s和3p轨道形成的杂化轨道比氧的2s和2p轨道形成的杂化轨道大，故C-S和S-H键分别比C-O和O-H键长。在甲硫醇中C-S和S-H键键长分别为0.182 nm和0.134 nm，都比甲醇中的C-O和O-H键长大。∠CSH则为96°，小于∠COH。

硫的电负性比氧小，所以硫醇的偶极矩也比相应的醇小。

Thiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl group of an alcohol), and the word is a portmanteau of "thion" + "alcohol," with the first word deriving from Greek θεῖον (theion) = "sulfur". The –SH functional group itself is referred to as either a thiol group or a sulfhydryl group.
