Web13. jan 2009 · A crucial point, when working with redox biology, is to avoid oxidation and thiol–disulfide exchange during sample preparation. The combined acidifying and denaturing effects of trichloroacetic acid (TCA) makes it an ideal choice for quenching redox reactions in cell extracts. Akin to the chemistry of alcohols, thiols form sulfides, thioacetals, and thioesters, which are analogous to ethers, acetals, and esters respectively. Thiols and alcohols are also very different in their reactivity, thiols being more easily oxidized than alcohols. Thiolates are more potent nucleophiles than the corresponding alkoxides.
