Thiol definition

WebThiols undergo oxidation in the presence of a base to produce disulfides. The mechanism of disulfide formation from thiols involves two steps. Step 1: The hydrogen present in sulfhydryl group is highly acidic in nature. A base can easily take away this hydrogen. Removal of acidic hydrogen from thiols will make them a potential nucleophile. In organic chemistry, a thiol , or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent. The −SH functional group itself is referred to as either a thiol group or a sulfhydryl group, or a sulfanyl group. Thiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl (−OH) group of an alcohol), and the word is a blend of "thio-" with "alcohol".

WebThiolates, not thiols, attack disulfide bonds. Hence, thiol–disulfide exchange is inhibited at low pH (typically, below 8) where the protonated thiol form is favored relative to the deprotonated thiolate form.
