In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH 3 and the structure −C(=O)−CH 3. It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium). In IUPAC nomenclature, an acetyl group is called an ethanoyl group.
Structure of an η 2-acyl complex, Cp 2 Zr(CO)(acetyl) +. [3] Acyl complexes are usually low-spin and spin-paired. Monometallic acyl complexes adopt one of two related structures, C-bonded and η 2-C-O-bonded. These forms sometimes interconvert. For the purpose of electron-counting, C-bonded acyl ligands count as 1-electron ligands, akin to ...
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 addition, acetyl-CoA is a precursor for the biosynthesis of various acetyl-chemicals, acting as an intermediate to transfer an acetyl group during the biosynthesis of those acetyl-chemicals. Acetyl-CoA is also involved in the regulation of various cellular mechanisms by providing acetyl groups to target amino acid residues for post ...
The reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a ...
N-terminal acetylation is the protein modification that occurs on the α-amino acid group at the N-termini of proteins. The backbone amino group on the first amino acid (α-amino group) on a protein N-terminus gets an acetyl group (-COCH 3) via acetyl-CoA, and this process is catalyzed by enzymes called N-terminal acetyltransferases (NATs).

In chemistry, an acyl group is a moiety derived by the removal of one or more hydroxyl groups from an oxoacid, [1] including inorganic acids. It contains a double-bonded oxygen atom and an organyl group ( R−C=O ) or hydrogen in the case of formyl group ( H−C=O ).
