WebJul 20, 2024 · 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 \(pK_a\) of a thiol is about 10, while the \(pK_a\) of an alcohol is 15 or higher: a stronger conjugate acid means a weaker conjugate base. WebThioesters and the origin of life. Some biochemists believe that the thioester bond was critical for the origin of life.One Nobel Prize winning scientist, Belgium's Christian de Duve, posits a "Thioester World" which preceded and developed into an "RNA World", itself the immediate precursor to the appearance of entities we would call organisms.. As de Duve …
WebMar 10, 2015 · Hence, the thioester bond has a more negative standard free energy of hydrolysis (−7.5 kcal/mole vs. about −5 kcal/mole for most oxygen esters). In many cases, it appears that thioesters are more reactive than oxygen esters, undergoing more facile nucleophilic displacement reactions at the acyl group. The reactivity of a thioester at the ... WebSulfide (organic) General structure of a sulfide with the blue marked functional group. In organic chemistry, an organic sulfide ( British English sulphide) or thioether is an organosulfur functional group with the connectivity R−S−R' as shown on right. Like many other sulfur-containing compounds, volatile sulfides have foul odors. [1]
