代谢
硫醇的代谢途径包括氧化成不稳定的亚磺酸(RSH),后者可进一步氧化成相应的亚磺酸(RSO2H)和磺酸(RSO3H);甲基化生成甲基硫化物,这些甲基硫化物可被氧化成甲硫醚氧化物和硫酮;与内源性硫醇(如谷胱甘肽)反应形成混合二硫化物;与葡萄糖醛酸结合;以及α-碳的氧化导致脱硫并形成醛中间体。/硫醇/
The metabolic pathways of thiols include oxidation to unstable sulfenic acids (RSOH), which may be oxidized to the corresponding sulfinic (RSO2H) and sulfonic acids (RSO3H); methylation to yield methyl sulfides, which can be oxidized to methyl sulfoxides and sulfones; reaction with endogenous thiols such as glutathione to form mixed disulfides; conjugation with glucuronic acid; and oxidation of the alpha-carbon resulting in desulfuration and formation of an aldehyde intermediate. /Thiols/
