3-Dehydroquinic acid
3-Dehydroquinic acid belongs to the class of organic compounds known as alpha-hydroxy acids and derivatives. These are organic compounds containing a carboxylic acid substituted with a hydroxyl group on the adjacent carbon. 3-Dehydroquinic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). In most organisms, 3-dehydroquinic acid is synthesized from D-erythrose-4-phosphate in two steps. However, archaea genomes contain no orthologs for the genes that encode these first two steps. Instead, archaeabacteria appear to utilize an alternative pathway in which 3-dehydroquinic acid is synthesized from 6-deoxy-5-ketofructose-1-phosphate and L-aspartate-semialdehyde. These two compounds are first condensed to form 2-amino-3,7-dideoxy-D-threo-hept-6-ulosonate, which cyclizes to 3-dehydroquinic acid. From 3-dehydroquinic acid and on to chorismate, the archaeal pathway appears to be identical to the bacterial pathway.

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. Its 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; its unstable and immediately undergoes decarboxylation to produce the 5-carbon compound, alpha-ketoglutarate . Oxalosuccinate is a substrate for cytoplasmic Isocitrate dehydrogenase and mitochondiral Isocitrate dehydrogenase (mitochondrial).
