Thioester compound example
WebOct 11, 2024 · Is a thioester or ester more stable? A thioester is more reactive than an ester, for example, because a thiolate (RS-) is a weaker base and better leaving group than an alcoxide (RO-). Recall from chapter 7 that the pKa of a thiol is about 10, while the pKa of an alcohol is 15 or higher: a stronger conjugate acid means a weaker conjugate base. WebAn example of thioester hydrolysis is the conversion of (S)-citryl CoA to citrate in the citric acid cycle (also known as the Krebs cycle). Reactivity of thioesters and acyl phosphates …
