Acylation is a reaction in which an acyl group becomes attached to some structural unit in a molecule. Examples include the Friefel-Crafts acylation adn the conversio of amines to amides.

What is the product formed by the acetylation of p-aminophenol with acetic anhydride and NaOH?
acetaminophen (n-acetate of 4-aminophenol)
Why Acetic acid not used in acetylation?
Because it can not form the acetyl group easily but above 1000 Celsius acetic acid may form acetic anhydride which may be used to produce acetyl ion. Acetylation by acetic acid using is possible by using cobalt chloride as catalyst with good yield
What does N stand for in N-acetylcysteine?
The N denotes the acetyl group attached to the nitrogen - taking place of the two hydrogens that were present before acetylation.
Which catalyst is used in esterification of glycerol with acetic acid?
Usually, the catalysts used for the acetylation (esterification with acetic acid) of glycerol are transition metallic oxides.For instance - ZrO2, WO3, TiO2, MoO3 and others.
How do you determine degree of deacetylation of chitosan using uv-visible spectrophotometer?
There is an article was wrote by Riccardo Muzzarelli and Roberto Rocchetti, the topic is determination of the degree of acetylation of chitosans by first deirivative ultraviolet spectrophotometry. Hope it may help you.
What is acetylation and which chemicals are commonly involved?
Acetylation describes the process of an introduction of an acetyl functional group into chemical compounds. Chemicals that are commonly involved are succinic acid.
What does the term 'histone acetylation' means?
Histones are proteins that organize DNA in the chromatin of eukaryotes (cells that have membrane enclosed nuclei). Acetylation means the introduction of acetyl group to a molecule. In essence, Histone Acetylation removes the positive charge on the histones which, in turn, causes a decrease in the interaction with negatively charged phosphates in DNA.
What are genomic imprinting DNA methylation and histone acetylation examples of?
Epigenetic Phenomena.
In eukaryotes what is active transcription generally associated with?
Both euchromatin and histone acetylation.
How can phenol be converted to aspirin?
you can say as it contain Phenol ring that is undergoes acetylation process to form -OCOCH3

How do DNA methylation and histone acetylation affect chromatin structure and the regulation of transcription?
When chromatin is tightly compacted and dense, it's called Heterochromatin. When chromatin is loosely packed, its called Euchromatin. Euchromatin is easily accessible to transcription enzymes, while herterochromatin makes transcription impossible because the enzymes cannot access the DNA. Therefore, a gene within heterochromatin cannot be expressed. Also, look up how histone modifications such as histone acetylation affect gene expression.
What has the author Yu-Chung Tsang written?
Yu-Chung Tsang has written: 'Non linear N-acetylation: study with sulphamethazine'
How would DNA make itself more compact?
Acetylation is the compacting of a DNA molecule, making it more compact and reduces its ability to be transcribed.
What does N stand for in N-acetylcysteine?
The N denotes the acetyl group attached to the nitrogen - taking place of the two hydrogens that were present before acetylation.
