Introduction to Calcium α-Ketoglutarate

Chemical Properties

• Chemical Name: Calcium α-Ketoglutarate
• Molecular Formula: C₅H₄CaO₅·nH₂O (where n represents the number of crystallization waters, commonly one hydrate)
• CAS Number: 71686-01-6
• Appearance: White to off-white crystalline powder, odorless, slightly bitter taste.
• Solubility: Readily soluble in water, with the aqueous solution being acidic.
• Stability: Stable under dry conditions; requires protection from light and sealed storage.

Biological Sources and Metabolism

• Natural Occurrence: Present in small amounts in mammalian tissues as an intermediate in the tricarboxylic acid (TCA) cycle.
• Synthetic Metabolism: Formed by the combination of α-ketoglutarate with calcium ions or by the deamination of glutamate followed by calcium binding.
• Functional Role: Acts as a key intermediate in energy metabolism, participating in the synthesis of amino acids, fatty acids, and nucleic acids.
