- The following compound has been found to be an inhibitor of penicillinase. The enzyme can be reactivated by hydroxylamine (NH2OH). Propose a mechanism to account for the inhibition and for the reactivation.Imidazoleglycerol‑phosphate dehydratase is an enzyme in the histine biosynthesis pathway. It catalyzes the E1 dehydration of D‑erthyro‑imidazole‑glycerol phosphate to imidazole acetol‑phosphate. This is a rare example of a biological E1 reaction, as most biological elimination reactions occur through E1cB instead. In this reaction, D‑erthyro‑imidazole‑glycerol phosphate is first protonated to form a good leaving group. Then, the leaving group is ejected to form the resonance‑stabilized carbocation shown. Draw curved arrows forming the most stable resonance structure to explain why this reaction goes through an E1 mechanism. Draw curved arrows to form the most stable resonance structure.Ozonolysis, osmylation, and epoxide formation with mCPBA are all what type of reactions? a.) reduction b.)oxidation c) bothd) neither
