Succinic semialdehyde (692-29-5)
gamma-oxybutyric acid · succinic semialdehyde, calcium salt
Succinic semialdehyde (SSA) is a GABA metabolite. It is formed from GABA by the action of GABA transaminase and further oxidised to become succinic acid, which enters TCA cycle.
Asparagusic acid (2224-02-4)
Asparagusic acid is an organosulfur compound with the molecular formula C4H6O2S2 and is systematically named 1,2-dithiolane-4-carboxylic acid. The molecule consists of a cyclic disulfide functional group (a 1,2-dithiolane) with a carboxylic acid side chain. It is found in asparagus and is believed to be the metabolic precursor to odorous sulfur compounds responsible for the distinctive smell of urine which has long been associated with eating asparagus.

acetylenedicarboxylic acid (142-45-0, 928-04-1)
2-butynedioic acid, potassium salt · 2-butynedioic acid
Acetylenedicarboxylic acid or butynedioic acid is an organic compound (a dicarboxylic acid) with the formula C4H2O4 or HO2C-C≡C-CO2H. It is a crystalline solid that is soluble in diethyl ether. The removal of two protons yields the acetylenedicarboxylate dianion C4O42−, which consists only of carbon and oxygen, making it an oxocarbon anion.
2-Biphenylcarboxylic acid (51317-27-2, 947-84-2)
B-2-CA · biphenyl-2-carboxylic acid
MELLITIC ACID (517-60-2)
benzene hexacarboxylic acid · mellitic acid, hexasodium salt · hexacarboxybenzene
Mellitic acid, also called graphitic acid or benzenehexacarboxylic acid, is an acid first discovered in 1799 by M. H. Klaproth in the mineral mellite (honeystone), which is the aluminium salt of the acid.
