acetyl coa thioester

What is a thioester?
Definition.
Thioesters are esters in which the linking oxygen atom is replaced by sulfur.
They are the product of dehydration reaction between a carboxylic acid derivative and a thiol.
Thioesters are common intermediates in biochemistry, for example, in acetyl-CoA, malonyl-CoA, acetoacetyl-CoA, and propionyl-CoA.
One key difference between thioesters and esters is their reactivity towards nucleophiles.
Thioesters are more reactive towards nucleophiles than esters, due to the lower electronegativity of sulfur compared to oxygen.

Does acetyl-CoA have a thiol group?

Before it can be incorporated into a growing fatty acid molecule, acetyl CoA must first be linked to a so-called 'acyl carrier protein' (ACP).
The acetyl group is linked to the acyl carrier protein via a thiol group on a carrier molecule that is covalently attached to the protein._{24 sept. 2022}

What are examples of thioesters?

Thioesters are common intermediates in many biosynthetic reactions, including the formation and degradation of fatty acids and mevalonate, precursor to steroids.
Examples include malonyl-CoA, acetoacetyl-CoA, propionyl-CoA, cinnamoyl-CoA, and acyl carrier protein (ACP) thioesters.

Acetyl-CoA is a thioester between the acyl group carrier, acetic acid and a thiol, coenzyme A. Acetyl-CoA, as a carrier of acyl groups, is an essential cofactor in the posttranslational acetylation reactions of histone and nonhistone proteins catalyzed by HATs.
