  • Thioester - Wikipedia
    General structure of a thioester, where R and R' are organyl groups, or H in the case of R In organic chemistry, thioesters are organosulfur compounds with the molecular structure R−C(=O)−S−R’
  • 2. 12: Thioesters- Biological Carboxylic Acid Derivatives
    Thioesters are biologically important carboxylic acid derivatives Acetyl coenzyme A is an important thioester in metabolism and transports two carbon atoms to the Citric Acid Cycle (Kreb's …
  • Thioester - an overview | ScienceDirect Topics
    A thioester is a biochemical acyl transfer reagent that is more reactive than esters, allowing for efficient transfer of acyl groups in cells due to its stability towards hydrolysis and reactivity towards nucleophiles
  • 21. 8 Chemistry of Thioesters and Acyl Phosphates . . . - Chemistry LibreTexts
    The acyl group of a thioester can be transferred to a water molecule in a hydrolysis reaction, resulting in a carboxylate An example of thioester hydrolysis is the conversion of (S)-citryl CoA to citrate in the citric acid cycle (also known as the Krebs cycle)
  • CHEM 440 - Thioesters - Gonzaga University
    In contrast to the various acyl derivatives employed in organic synthesis, one key derivative - the thioester - plays a disproportionately large role in metabolism The most common thioesters are based on phosphopantetheine (which is the biochemically active form of the pantothenate), which includes coenzyme A ("A" for acylation)
  • What Is a Thioester Bond and Why Is It Important?
    A thioester bond is a chemical linkage involving a sulfur atom that is fundamental to the processes of life This bond is a recurring feature in metabolic pathways, playing a central part in how organisms capture, store, and utilize energy from their environment
  • Intro to Thioesters Explained: Definition, Examples, Practice . . . - Pearson
    In organic chemistry, thioesters are a class of compounds that contain a sulfur atom bonded to an acyl group To name a thioester, it is essential to identify the substituents and the parent chain correctly In this case, the thioester has a sulfur atom attached to a phenyl group, which is derived from benzene
  • 21. 8: Chemistry of Thioesters and Acyl Phosphates - Biological . . .
    As mentioned in the chapter introduction, the substrate for a nucleophilic acyl substitution reaction in living organisms is generally either a thioester (RCOSR′) or an acyl phosphate (RCO 2 PO 3 2 – or RCO 2 PO 3 R′ –) Neither is as reactive as an acid chloride or acid anhydride, yet both are stable enough to exist in living organisms
  • What is a thioester and how is it formed? | TutorChase
    A thioester is a type of chemical bond formed between a carboxylic acid and a thiol group Thioesters are formed through a reaction between a carboxylic acid and a thiol group The thiol group, which contains a sulfur atom, replaces the hydroxyl group of the carboxylic acid, resulting in the formation of a thioester bond
