2Oxopentanedioic

2-Oxopentanedioic acid, also known as alpha-ketoglutaric acid or oxoglutarate, is a dicarboxylic acid with the chemical formula C5H6O5. It is a crucial intermediate in the citric acid cycle, also known as the Krebs cycle, a central metabolic pathway in aerobic respiration. In this cycle, 2-oxopentanedioic acid is formed from isocitrate and subsequently converted to succinyl-CoA.

The compound plays a significant role in amino acid metabolism. It is a key product of the deamination of glutamate, an abundant amino acid. This reaction allows for the transfer of nitrogen atoms, facilitating the synthesis and degradation of amino acids. 2-Oxopentanedioic acid can also be transaminated to form glutamate, linking carbohydrate and protein metabolism.

Beyond its role in energy production and amino acid interconversion, 2-oxopentanedioic acid has been investigated for various physiological functions. It is involved in processes such as ammonia detoxification in some organisms and has been studied for potential therapeutic applications, although its specific roles in human health are still a subject of ongoing research. Its presence and activity are essential for cellular energy homeostasis and nitrogen balance.
