نویسندگان
چکیده
The title compound, C(11)H(16)O(4), crystallizes with three molecules in the asymmetric unit. The cyclo-hexane ring adopts a chair conformation. Inter-molecular O-H⋯O hydrogen bonds are observed and these help to establish the crystal packing.

A novel synthesis of succinic acid type Gemini surfactant by the functional group interconversion of Corynomicolic acid.
2,3-Bis(undecyl)succinic acid, succinic acid type Gemini surfactant, was successfully synthesized from Corynomicolic acid by the functional interconversion of OH of Corynomicolic acid to COOH via (1) mesylation of OH of syn-isomer, (2) elimination of methanesulfonate group using base to E-alpha,beta-unsaturated ester, (3) Michael addition of CN(-) with 18-crown-6 and (4) hydrolysis. In most hyd...
متن کاملThe Antiketogenic Activity of Succinic Acid.
Koranyi and Szent-Gyorgyi have reported (1, 2) that relatively small doses of succinic acid would reduce or abolish the ketosis in diabetes. We have been unable to demonstrate this action of succinic acid. In Table I are presented three typical examples of the result of administering succinic acid to diabetic patients. All of these patients had been on their regime for some time and their diets...
متن کاملN′-Hydroxypyridine-2-carboximidamide–succinic acid (2/1)
The asymmetric unit of the title co-crystal, C6H7N3O·0.5C4H6O4, comprises one N'-hy-droxy-pyridine-2-carboximidamide mol-ecule and half a succinic acid mol-ecule (the whole molecule is generated by inversion symmetry). In the crystal, mol-ecules are assembled into columns along [110], via strong N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds.
متن کاملMetabolic engineering of Escherichia coli for enhanced production of succinic acid, based on genome comparison and in silico gene knockout simulation.
Comparative analysis of the genomes of mixed-acid-fermenting Escherichia coli and succinic acid-overproducing Mannheimia succiniciproducens was carried out to identify candidate genes to be manipulated for overproducing succinic acid in E. coli. This resulted in the identification of five genes or operons, including ptsG, pykF, sdhA, mqo, and aceBA, which may drive metabolic fluxes away from su...
متن کاملBis(ethanolaminium) succinate–succinic acid (1/1)
The asymmetric unit of the title compound, 2C(2)H(8)NO(+)·C(4)H(4)O(4) (2-)·C(4)H(6)O(4), consists of half a succinate anion, half a succinic acid mol-ecule and one ethano-laminium cation. The succinate anion and succinic acid mol-ecule, both of which are located on inversion centres, are linked by O-H⋯O hydrogen bonds, forming a chain along the [2[Formula: see text]0] direction. The chain and ...
