In IUPAC nomenclature, an acetyl group is called an ethanoyl group. An acetyl group contains a methyl group ( −CH 3 ) that is single-bonded to a carbonyl ( C=O ), making it an acyl group . The carbonyl center of an acyl radical has one non-bonded electron with which it forms a chemical bond to the remainder (denoted with the letter R ) of the ...
It introduces an acetyl group into a chemical compound. Such compounds are termed acetate esters or simply acetates. Deacetylation is the opposite reaction, the removal of an acetyl group from a chemical compound.
Acetyl-CoA (acetyl coenzyme A) is a molecule that participates in many biochemical reactions in protein, carbohydrate and lipid metabolism. [2] Its main function is to deliver the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production.

The intermediate collapses and expels the leaving group (X) to give the substitution product 3. While nucleophilic acyl substitution reactions can be base-catalyzed, the reaction will not occur if the leaving group is a stronger base than the nucleophile (i.e. the leaving group must have a higher pK a than the nucleophile). Unlike acid ...
Addition of an acetyl group, which carries a negative charge, effectively removes the positive charge and hence, reduces the interaction between the histone tail and the nucleosome. [18] This opens up the usually tightly packed nucleosome and allows transcription machinery to come into contact with the DNA template, leading to gene transcription .
It also contains an ester functional group (in red), and an acetyl functional group (encircled with dark green). Other divisions can be made. In organic chemistry, a moiety (/ ˈ m ɔɪ ə t i / MOY-ə-tee) is a part of a molecule [1] [2] that is given a name because it is identified as a part of other molecules as well.
In organic chemistry, the acetoxy group (abbr. AcO or OAc; IUPAC name: acetyloxy [1]), is a functional group with the formula −OCOCH 3 and the structure −O−C(=O)−CH 3. As the -oxy suffix implies, it differs from the acetyl group (−C(=O)−CH 3) by the presence of an additional oxygen atom. The name acetoxy is the short form of acetyl-oxy.
