thioester: meaning, origin, definition - WordSense Dictionary
WebDefinition. Thioesters are esters in which the linking oxygen atom is replaced by sulfur. They are the product of dehydration reaction between a carboxylic acid derivative and a thiol. Thioesters are common intermediates in biochemistry, for example, in acetyl-CoA, malonyl-CoA, acetoacetyl-CoA, and propionyl-CoA. WebIn fact, the thioester bond is sometimes exchanged with a phosphoester bond (like the one in ATP) during metabolism of acetyl-CoA Acetyl-CoA + Pi ⇌ Acetyl-phosphate + CoA Notice that this reaction has a positive Δ r G’ m ≈ 10 kJ/mol, meaning that it would flow in the reverse direction (forming acetyl-CoA) if all the reactants had 1 mM ... fatty liver protein powder

Here, we present high-resolution human ... In organic chemistry, thioesters are organosulfur compounds with the molecular structure R−C(=O)−S−R’. They are analogous to carboxylate esters (R−C(=O)−O−R’) with the sulfur in the thioester replacing oxygen in the carboxylate ester, as implied by the thio- prefix. They are the product of esterification of a … See more The most typical route to thioester involves the reaction of an acid chloride with an alkali metal salt of a thiol: Another common route entails the displacement of halides by the alkali metal salt of a See more Thionoesters are isomeric with thioesters. In a thionoester, sulfur replaces the carbonyl oxygen in an ester. Methyl thionobenzoate is C6H5C(S)OCH3. Such compounds are … See more Thioesters hydrolyze to thiols and the carboxylic acid: RC(O)SR' + H2O → RCO2H + RSH The carbonyl center in thioesters is more reactive toward … See more Thioesters are common intermediates in many biosynthetic reactions, including the formation and degradation of fatty acids and See more • Thiocarboxylic acid • Liebeskind-Srogl coupling • Aldrithiol-2 See more WebMay 26, 2024 · Introduction.
