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 is the significance of acetylation charge in the process of protein modification?
Acetylation is a common type of protein modification that involves adding an acetyl group to a protein molecule. This process can affect the protein's structure and function, as well as its interactions with other molecules in the cell. The acetylation charge plays a significant role in regulating the activity of proteins and can impact various cellular processes, such as gene expression, cell signaling, and metabolism.
Reaction of aniline with glacial acetic acid?
Aniline reacts with glacial acetic acid to form N-acetylaniline as the primary product. This reaction involves the acetylation of the amino group of aniline by the acetic acid to form the acetylated product. The reaction is usually carried out in the presence of a catalyst like sulfuric acid to facilitate the acetylation process.
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.
What is covalent modification?
Covalent modification refers to the attachment of chemical groups, such as phosphate or methyl groups, to proteins to regulate their activity, localization, or stability. This type of modification can alter the functional properties of proteins by affecting their structure and interactions with other molecules. Examples include phosphorylation and acetylation.
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 part does acetylation play in gene expression?
Acetylation of histones, which are proteins that help package DNA in the cell, typically leads to a more relaxed chromatin structure. This allows for easier access of the transcriptional machinery to the DNA, promoting gene activation and expression. Acetylation is often associated with increased gene expression due to this facilitating effect on transcription.
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.
Why does histone acetylation lead to an increase in gene expression?
Histone acetylation leads to an increase in gene expression because it loosens the interaction between histones and DNA, making it easier for transcription factors to access the DNA and activate gene expression.

How can phenol be converted to aspirin?
you can say as it contain Phenol ring that is undergoes acetylation process to form -OCOCH3
WHY IS CARBOXYL GROUP NOT ACETYLATED?
The carboxyl group (-COOH) is not acetylated because it is already a fully functionalized group that contains both a carbonyl (C=O) and a hydroxyl (–OH) component. Acetylation typically involves the addition of an acetyl group (–COCH3) to nucleophilic sites, and the hydroxyl group in a carboxylic acid is not a suitable site for acetylation due to its strong acidity and reactivity. Additionally, acetylation would convert the carboxyl group into an ester, which alters its chemical properties and functionality.
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.
