Chemical Information
FooDB Nameoxalosuccinate
DescriptionOxalosuccinic acid, also known as oxalosuccinate or 1-oxopropane-1,2,3-tricarboxylate, belongs to tricarboxylic acids and derivatives class of compounds. Those are carboxylic acids containing exactly three carboxyl groups. Oxalosuccinic acid is slightly soluble (in water) and a moderately acidic compound (based on its pKa). Oxalosuccinic acid can be found in a number of food items such as japanese chestnut, poppy, wax apple, and hyssop, which makes oxalosuccinic acid a potential biomarker for the consumption of these food products. Oxalosuccinic acid exists in all living species, ranging from bacteria to humans. Oxalosuccinic acid/oxalosuccinate is an unstable 6-carbon intermediate in the tricarboxylic acid cycle. It's an alpha-keto compound, formed during the oxidative decarboxylation of isocitrate to alpha-ketoglutarate, which is catalyzed by the enzyme isocitrate dehydrogenase. Oxalosuccinate never leaves the active site of the enzyme, however; it's unstable and immediately undergoes decarboxylation to produce the 5-carbon compound, alpha-ketoglutarate .
