What is Coenzyme A?
Coenzyme A (CoA), as a carrier in enzymatic reactions, serves as a vital cofactor in over 70 metabolic pathways within the body. It is a crucial intermediate in energy substance metabolism, widely present in animals, plants, microorganisms, and cultured cells. In energy substance metabolism, it plays a pivotal role.
Acyl-CoA, a CoA derivative, is a coenzyme involved in fatty acid metabolism. It is readily subjected to β-oxidation, leading to the formation of acetyl-CoA. Acetyl-CoA is a product of pyruvate decarboxylation and fatty acid β-oxidation. When pyruvate enters the mitochondrial matrix, it undergoes oxidative decarboxylation, converting into acetyl-CoA through the pyruvate dehydrogenase complex. Simultaneously, pyruvate and its carboxyl group are released as carbon dioxide. During this process, pyruvate serves as the carbon source for fatty acid synthesis, cholesterol synthesis, and ketogenesis. Thorough oxidation of the three major nutrients converges to yield acetyl-CoA, which enters the tricarboxylic acid cycle, ultimately generating ATP. In this manner, fats are converted into the universal biochemical energy carrier, ATP.
The Physiological and Biochemical Functions of Coenzyme A
Fatty Acyl-CoA (Acyl-CoA) is the thioester derivative formed by the binding of acyl groups generated during the metabolism of fatty acids to coenzyme A (CoA). It results in sulfur ester derivatives such as acetyl-CoA, butyryl-CoA, and palmitoyl-CoA, primarily located in the mitochondria and cytoplasmic matrix. Coenzyme A and its sulfur ester derivatives serve as carriers in enzymatic reactions, extensively participating in central metabolic pathways. For instance, acetyl-CoA is an indispensable cofactor in the citric acid cycle and fatty acid oxidation, reflecting changes in cellular core metabolism. Succinyl-CoA, acting as both a substrate for fatty acid synthesis and a regulator of fatty acid oxidation, plays a pivotal role. Coenzyme A also regulates the oxidative decarboxylation of pyruvate. Additionally, these derivatives can modify proteins through acetylation, propionylation, butyrylation, and malonylation, among others. These acylation modifications serve as regulators of protein function and activity, prominently observed in tumor metabolism regulation.
Coenzyme A Quantification Service
Given the pivotal role of Coenzyme A (CoA) substances in transcription regulation and cellular metabolism in organisms, the demand for their detection has been steadily increasing as mechanistic studies deepen. Creative Proteomics employs triple quadrupole mass spectrometry to conduct absolute qualitative and quantitative analysis of over a dozen Acyl-CoA substances, contributing to in-depth mechanistic research.
Our well-established and reliable methods for absolute quantification of CoA substances allow for simultaneous determination of multiple CoA substances in samples. This approach is applicable to various biological specimens, enabling precise quantification of CoA substances with diverse structures in a single analysis. The detection limit can reach the ng level, making it particularly suitable for high-tech research.
