WebIn organic chemistry, a dithiol is a type of organosulfur compound with two thiol (−SH) functional groups. Their properties are generally similar to those of monothiols in terms of … 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 cystine unit with a disulfide bond (−S−S−). Disulfide bonds can contribute to a protein's tertiary structure if t…
