However, it was observed short-chain PFAS accumulated during ... WebCysteine side chains can exist in distinct oxidation states depending on the pH and redox potential of the environment, and cysteine oxidation plays important yet complex regulatory roles. Compared with the effects of post-translational modifications such as phosphorylation, the effects of oxidation of cysteine to sulfenic, sulfinic, and sulfonic acid …
WebOct 15, 2014 · A problem with all 3 conditions is that oxidation will only occur if the material to be oxidized is somewhat soluble in the reaction medium. The milder basic conditions are generally preferred for the oxidation of aromatic alkyl side chains because with the milder basic conditions an organic co-solvent that is soluble in water can be employed to … WebNov 14, 2012 · The oxidation of an aromatic side chain does not require any of these factors. All that is needed is a benzylic carbon with at least one hydrogen attached to it. The oxidizing agents that can be used are chromic acid (using Na 2 Cr 2 O 7 or CrO 3 in sulfuric acid and water) or potassium permanganate (KMnO 4).
