Ketoglutaric acid, also known as alpha-ketoglutaric acid, is a vital compound found in many living organisms. This organic acid plays a crucial role in cellular energy metabolism and protein synthesis. Synonymous with 2-oxoglutaric acid, ketoglutaric acid is an intermediate in the citric acid cycle, which is the main process for generating energy in the cells. Additionally, it is commonly referred to as alpha-ketoglutarate. This multifunctional molecule acts as a precursor for the production of important biomolecules, such as amino acids and neurotransmitters. Its significance extends to various scientific fields, including biochemistry, metabolism, and nutrition.
