Cysteine and cystine As the functional group of the amino acid cysteine, the thiol group plays a very important role in biology. When the thiol groups of two cysteine residues (as in monomers or constituent units) are brought near each other in the course of protein folding, an oxidation reaction can generate a … See more 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 … See more Thiols having the structure R−SH, in which an alkyl group (R) is attached to a sulfhydryl group (SH), are referred to as alkanethiols or alkyl thiols. Thiols and alcohols have similar connectivity. … See more Odor Many thiols have strong odors resembling that of garlic. The odors of thiols, particularly those of low molecular weight, are often strong and … See more In industry, methanethiol is prepared by the reaction of hydrogen sulfide with methanol.
