α-ketoglutaric acid is one of two Ketoglutaric acid derivatives (the term “Ketoglutaric acid” mostly refers to the alpha type unless otherwise specified. β -ketoglutaric acid is a white fine crystalline powder with different ketone groups and is less commonly used. The melting temperature of 113.5 ℃. Soluble in water, alcohol, very difficult to dissolve in ether, long storage becomes pale gray yellow, easy deliquescence.
The anion of this substance, α -ketoglutarate, is an important biological compound. It is a ketoic acid product of glutamic acid deamination and an intermediate product of the tricarboxylic acid cycle.
