Chemical Information
FooDB Name2-Oxopentanedioic acid
DescriptionFlavouring ingredient Alpha-ketoglutaric acid is an important biological compound and is a key intermediate in the Krebs cycle. Alpha-ketoglutaric acid occurs naturally within cells. One of its functions is to combine with ammonia to form glutamic acid and then glutamine. Another function is to combine with nitrogen released in the cell, therefore preventing nitrogen overload. (wikipedia). 2-Oxopentanedioic acid is found in many foods, some of which are carrot, breadnut tree seed, sweet potato, and komatsuna.
