Calcium α-Ketoglutarate (Calcium 2-Oxoglutarate) is the calcium salt of α-ketoglutaric acid, a key intermediate in the tricarboxylic acid (TCA) cycle. This compound integrates the metabolic functions of α-ketoglutarate with the essential mineral calcium, providing a combined approach to cellular energy metabolism and bone health support.
α-Ketoglutarate serves as a critical node in the TCA cycle, linking carbohydrate, amino acid, and fatty acid metabolism. It also functions as a nitrogen scavenger and a precursor for glutamate and glutamine synthesis. In recent years, it has attracted attention for its potential in healthy aging, cellular energy, and amino acid metabolism applications.
