acetylation reaction
As stated above, in Organic Chemistry, acylation is the process or mechanism of adding an acyl group (RCO-) to a particular compound.
The reaction basically involves substitution by a nucleophile (electron donor) at the electrophilic carbonyl group (C = O) of a carboxylic acid derivative.
What is acetylation and what does it do?
Acetylation usually occurs on lysine residues, neutralizing their positive charge and thereby causing histones to drift away from DNA, which has a negative charge.
The released structure facilitates access to transcriptional machinery such as transcription factors and RNA polymerase II.
What is the acetylation reaction?
What is Acetylation? Acetylation is a chemical reaction in which a hydrogen atom is substituted for an acetyl group (CH3C=O. group) in a compound.
The products formed in acetylation reactions typically have an acetoxy functional group.
What is the reaction of acetyl?
In chemistry, acetylation is an organic esterification reaction with acetic acid.
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.
