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 …

Webthioesters as thermodynamically activated compounds in prebiotic systems, and (2) the use of thiol–thioester exchange for applications in high-affinity reversible binding or self-assembly in water. The ubiquity of thioesters in biology implicates them as prospective compounds of importance to the origin of life. Web硫酯(Thioester)是一个硫原子和一分子酰基(烷烃与一碳氧双键分子所形成的共价键,或可看成有机酸脱除羟基而成的有机根)共价结合形成的的化学物质, 通式为R-S-CO-R'。硫酯是高能化学键。 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 ... leach barn building hillsboro ky
