Acetate - C2H3O2(−)

What is Acetate?

Acetate is a chemical compound with a formula C2H3O2. It is also known as Acetate Ion or Monoacetate. It is a salt formed by the combination of acetic acid with alkaline, metallic, earthy, or nonmetallic or other bases.

The conversion of pyruvate to acetyl-coenzyme A is carried out with the help of an enzyme called pyruvate dehydrogenase. The acetyl-CoA is further converted to acetate in E. coli and simultaneously produces ATP by substrate-level phosphorylation. The entire process requires two enzymes viz acetate kinase and phosphate acetyltransferase.

acetyl-CoA + Phospate → acetyl-Phospate+CoA

acetyl-Phospate+ADP → acetate + ATP

Fermentation of Acetate

Acetic acid undergoes dismutation reaction to generate carbon dioxide and methane.

CH3COO + H+ → CH4 + CO2 ΔG° = −36 kJ/mol

The reaction is carried out in the presence of catalyst methanogen archaea. One electron is transferred from the carboxylic group to the methyl group of acetic acid to generate carbon dioxide and methane gas.

Frequently Asked Questions

What elements are in acetate?

Both metallic acetates are inorganic salts of a metal cation and acetate anion, a polyatomic ion consisting of two carbon atoms ionically bound to three hydrogen atoms and two oxygen atoms (Symbol: CH3COO) with a total formula weight of 59.05.

What is the difference between acetate and acetic acid?

The main distinction between acetate and acetic acid is that acetate is a neutral compound, while acetate is an anion with a net negative electric charge. Acetic acid is an organic compound that helps create vinegar while acetate ion is the acetic acid’s conjugate base.

Is Acetate a base or acid?

Sodium acetate is a basic salt; the acetate ion will deprotonate water, thereby increasing the pH of the solution. Acid salts are the converse of the basic salts; they are formed in the neutralization reaction between a strong acid and a weak base. The weak-base conjugate acid makes the salt acidic.

What are the advantages of acetate?

This is among the most flexible fabrics and can resist wrinkling. ADVANTAGES: Has a silky appearance, a luxurious feel to it. DISADVANTAGES: The dyes can fade or bleed, are prone to heat, and are relatively poor fibres. Hand wash acetate clothes with warm water, and just a light-duty detergent.

How is acetate produced?

The acetate fiber is developed by using acetic anhydride to react with high purity wood pulp. The acetate flakes formed by this chemical reaction are dissolved in a solvent, filtered, and modified to obtain a solution for spinning stock.

The acetate anion is one from the carboxylate family. It is considered as a conjugate base of acetic acid. Acetic acid gets converted to acetate at a pH above 5.5. A common anion in biology where organisms utilize it in the form of acetyl coenzyme A. It is proposed that acetate produced by oxidizing ethanol is a key factor to cause hangovers.
