Glutaconic acid
Encyclopedia
trans-Glutaconic acid is an organic compound
with formula
HO2CCH=CHCH2CO2H. This dicarboxylic acid
exists as a colorless solid and is related to the saturated
chemical glutaric acid
, HO2CC(CH2)3CO2H. Ester
s and salts of glutaconic acid are called glutaconates.
, cis-glutaconic acid, has a noticeably lower melting point (130–132 °C). It can be prepared by bromination of levulinic acid
followed by treatment of the dibromoketone with potassium carbonate.
Glutaconic anhydride, which forms by dehydration the diacid
, exists mainly as the dicarbonyl tautomer
in solution. It is a colorless solid melting at 77–82 °C. Either the cis or trans diacid can be used to make it: the trans form isomerizes under the reaction conditions.
, 3-hydroxglutaric, and glutaconic acids are structurally related metabolite
s. In Glutaric aciduria type 1, glutaconic acid accumulates, resulting in brain damage.
Organic compound
An organic compound is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon. For historical reasons discussed below, a few types of carbon-containing compounds such as carbides, carbonates, simple oxides of carbon, and cyanides, as well as the...

Glutaric acid
Glutaric acid is the organic compound with the formula HO2C3CO2H. Although the related "linear" dicarboxylic acids adipic and succinic acids are water-soluble only to a few percent at room temperature, the water-solubility of glutaric acid is over 50%....

Ester
Esters are chemical compounds derived by reacting an oxoacid with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH group is replaced by an -O-alkyl group, and most commonly from carboxylic acids and...
