11. The molecule consists of two thiol groups and linked via a pair of amide groups. 12. This colourless viscous liquid consists of a benzene ring with a pair of adjacent thiol groups . 13. Finally, thiol groups on enzymes are reduced by a change in the redox state of the stroma. 14. This allows for the binding of the substrate ACV to the deprotonated thiol group of the cysteine residue. 15. They can be classified according to the relative location of the two thiol group on the organic compound. 16. Sodium nitroprusside is also useful in the identification the mercaptans ( thiol groups ) in the nitroprusside reaction. 17. The nucleophilic thiol group allows cysteine to conjugate to other groups, e . g ., in prenylation. 18. Disulfide bonds in proteins are formed between the thiol groups of cysteine residues by the process of oxidative folding. 19. Because of this reactivity with thiols, PCMB is also used in titrimetric quantification of thiol groups in proteins. 20. It is commonly used to bind covalently with the thiol group of cysteine so the protein cannot form disulfide bonds.
