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.
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 ...
It also contains an ester functional group (in red), and an acetyl functional group (encircled with dark green). Other divisions can be made. 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 ...
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 ).
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 ...
In organic chemistry, an active ester is an ester functional group that is highly susceptible toward nucleophilic attack. Activation can be imparted by modifications of the acyl or the alkoxy components of a normal ester, say ethyl acetate. Typical modifications call for electronegative substituents.
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).

An acyl halide (also known as an acid halide) is a chemical compound derived from an oxoacid [1] by replacing a hydroxyl group (−OH) with a halide group (−X, where X is a halogen). [ 2 ] In organic chemistry , the term typically refers to acyl halides of carboxylic acids ( −C(=O)OH ), which contain a −C(=O)X functional group consisting ...
