Anthracene-1,8-dicarboxylic Acid
Acta Crystallographica Section C Crystal Structure Communications, 1996Anthracene-1,8-dicarboxylic acid, C16H10O4, crystallized in the noncentrosymmetric space group P2(1)2(1)2(1). The carboxyl H and O atoms are ordered. The carboxyl groups make angles of 13.9 (2) and 21.6 (2) degrees with the best-fit core plane and the average distance of the core atoms from this plane is 0.018 (12) A.

Engineering microorganisms for the biosynthesis of dicarboxylic acids
Biotechnology Advances, 2021Dicarboxylic acids (DCAs) are important commodity chemicals which have been widely applied in polymer, food and pharmaceutical industries. Biosynthesis of DCAs from renewable carbon sources represents a promising alternative to chemical synthesis. Over the years, the recombinant strains have been constructed to produce an increasing number of DCAs.

Journal of Biochemistry, 2003
The reaction of Escherichia coli aspartate aminotransferase (AspAT) with glutamate and other C5-dicarboxylates was analyzed in order to compare its mechanism of action toward C5 substrates with that toward C4 substrates, which had been extensively characterized.

Rat liver metabolism of dicarboxylic acids
American Journal of Physiology-Gastrointestinal and Liver Physiology, 1989Recently, we demonstrated in rat liver that dicarboxylic acids containing more than five carbons can be activated by a microsomal dicarboxylyl-CoA synthetase (J. Vamecq, E. de Hoffmann, and F. Van Hoof. Biochem. J. 230: 683-693, 1985). The products of this reaction, dicarboxylyl-CoA esters, were found to be substrates for an H2O2-generating ...

Enantioselective Synthesis of Diamino Dicarboxylic Acids
The Journal of Organic Chemistry, 1999The preparation of alkyl diamino dicarboxylic acids with high optical purity (100% ee, >98.5% de) and high yields based on asymmetric catalytic hydrogenation is described. The required prochiral precursors are prepared from dialdehydes and Z-, Boc-, and acetyl-protected phosphonoglycines.

Metabolism of dicarboxylic acids in rat hepatocytes
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1990[carboxyl-14C]Dodecanedioic acid (DC12) is metabolized in hepatocytes at a rate about two thirds that of [1-14C]palmitate. Shorter dicarboxylates (sebacic (DC10), suberic (DC8), and adipic (DC6) acid) are formed, mainly DC6, less DC8 and only a little DC10.

Characterization of Dicarboxylic Acids for Cellulose Hydrolysis
Biotechnology Progress, 2001AbstractIn this paper, we show that dilute maleic acid, a dicarboxylic acid, hydrolyzes cellobiose, the repeat unit of cellulose, and the microcrystalline cellulose Avicel as effectively as dilute sulfuric acid but with minimal glucose degradation. Maleic acid, superior to other carboxylic acids reported in this paper, gives higher yields of glucose ...
