巯基基团是细胞保持正常结构和功能的重要基团。巯基化合物可以通过提供游离的巯基基团而保持细胞内氧化还原的正常比率和蛋白巯基的功能状态。巯基基团还可以调节受体的功能。巯基化合物对兴奋性氨基酸受体、抑制性氨基酸受体和烟碱型乙酰胆碱受体等细胞膜受体均可发挥调节作用 Sulfhydryl groups are important groups in which cells maintain normal structure and function. Thiol compounds can maintain the normal rate of intracellular redox and the functional status of the thiol group of proteins by providing free thiol groups. The thiol group can also modulate the function of the receptor. Sulfhydryl compounds exert modulatory effects on the receptors of the plasma membrane, such as excitatory amino acid receptors, inhibitory amino acid receptors and nicotinic acetylcholine receptors
