- 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.arrow_forwardIn aspirin synthesis from acetic anhydride and salicyclic acid, how does the type of mechanism affect the yield and how we improve the yield (are there any alternative pathways)?arrow_forwardGlyceryl tricaprate (or tricaprin) is a triacylglycerol used in foods, drugs, and cosmetics as an additive.
