Definition of Acetate

Acetic acid and a base combine to generate a salt known as an acetate (/aestet/) (e.g. alkaline, earthy, metallic, nonmetallic or radical base). The conjugate base or ion, specifically the negatively charged ion known as an anion, that is generally present in aqueous solution and has the chemical formula C2H3O2- is also referred to as "Acetate" Acetates are another name for the neutral molecules that are produced when an acetate ion and a positive ion (known as a cation) combine (hence, acetate of lead, acetate of aluminum, etc.). The most basic of these is hydrogen acetate, also known as acetic acid, along with the polyatomic anion CH3CO2- or CH3COO.


The majority of the yearly industrial output of acetic acid, which is around 5 billion kg, is used to create acetates, which are typically polymers. Acetate is the most prevalent building block for biosynthesis in nature.



Acetate in biology

A prevalent anion in biology is acetate. It is mostly used by organisms as acetyl coenzyme A.


It has been suggested that acetate produced by the oxidation of ethanol is a major factor in creating hangovers after it was discovered that intraperitoneal injection of sodium acetate (20 or 60 mg per kg body mass) caused headache in sensitized rats. The adenosine receptor antagonist coffee was observed to reduce nociceptive behavior in rats after ethanol administration. Increased serum acetate levels cause adenosine to accumulate in various organs, including the brain.


The innate immune response to harmful bacteria, such as the respiratory pathogen Haemophilus influenzae, can be impacted by acetate's known immunomodulatory capabilities.
