Background

BOC Sciences offers our customers a wide range of coenzyme A products, you can find the right product for your project development in our list. Coenzyme A can activate the metabolism of substances, enhance the oxidation of substances in the body and supply energy. Coenzyme A is the main active form of pantothenic acid in living organisms and is formed by 3',5'-ADP linked to 4-phosphopantothenyl-β-mercaptoethylamine by a phosphoric anhydride bond. Coenzyme A contains active sulfhydryl groups that can combine with acyl groups to form sulfolipids, and thus can serve as a coenzyme for acyltransferases, which play a role in transferring acyl groups in the metabolism of sugars, proteins, lipids, and other metabolic processes.

Coenzyme A Structure

Adenosine diphosphate - Adenosine diphosphate is the nucleotide portion of coenzyme A and consists of adenine and diphosphate groups. It is attached to the nucleotide structure of coenzyme A to provide energy and stability.

Pantothenic acid (PA) - PA is the truncated portion of coenzyme A, also known as bitartrate. It consists of a chain containing five carbon atoms and an acyl group (thiol group). The acyl group is the active part of coenzyme A and is involved in metabolic reactions by being attached to other molecules through ester bonds.

Choline - Choline is the choline ester portion of coenzyme A and is attached to PA by a phosphodiester bond. Choline plays a supporting and stabilizing role in the structure of coenzyme A.

Biosynthesis of Coenzyme A

First, bitartrate is chosen as the precursor substance for coenzyme A. It is then combined with bitartrate kinase enzyme to form phospho-bitartrate.
Then, phospho-bitartrate was reacted with cysteine to form 4'-phospho-bitartrate.
Next, 4'-phospho-bitartrate undergoes a dephosphorylation reaction to form 4'-diphospho-bitartrate.
Finally, 4'-diphosphobetaine reacts with β-pyruvate to produce coenzyme A.

As an important cofactor in various fields, coenzyme A has a wide range of applications with the reconstruction of the coenzyme A biosynthetic pathway and the resolution of the structure and function of key enzymes in the synthetic pathway.

Coenzyme A Function

As a cofactor, coenzyme A participates in several enzymatic reactions, regulates cellular metabolic processes, and maintains normal cellular function and energy supply.

Formation of Acetyl Coenzyme A

Coenzyme A combines with acetylase to form acetyl coenzyme A. Through the acetylation reaction, acetyl coenzyme A is able to transfer acetyl groups to other molecules, thus affecting metabolic processes.

Tricarboxylic Acid Cycle

Coenzyme A participates in the tricarboxylic acid cycle (also known as the Krebs cycle or the citric acid cycle) by translocating acetyl coenzyme A into the cycle reactions that produce energy and provide intermediates.

Lipid Metabolism

Coenzyme A is involved in the synthesis of fatty acids by transferring the acetyl group to the carboxyl group of long-chain fatty acids to form fatty acyl coenzyme A. Coenzyme A is also involved in the beta-oxidation of fatty acids, which breaks down fatty acyl coenzyme A into acetyl coenzyme A and generates energy.

BOC Sciences plays a vital role in providing high-quality coenzyme A to support cutting edge research and development in the biotechnology and pharmaceutical industries, if you are interested in our lipid synthesis and lipid analysis, please get in touch with us.
