The consumption of plant-based herbal formulations have been on the increase in recent times, due to their medicinal properties, however, identification, isolation and characterization bioactive constituents for specific health therapy safety remained an issue concern. This research identified, isolated characterized succinic acid from saponin fraction Mangifera indica (mango leaf SPEM) hexamet...

In the present paper we describe a new carboxylic acid transporter in Escherichia coli encoded by the gene yaaH. In contrast to what had been described for other YaaH family members, the E. coli transporter is highly specific for acetic acid (a monocarboxylate) and for succinic acid (a dicarboxylate), with affinity constants at pH 6.0 of 1.24±0.13 mM for acetic acid and 1.18±0.10 mM for succini...

The aim of this study was to improve enteric properties of shellac by the formation of succinate derivative through dry media reaction. Shellac and succinic anhydride were mixed and then co-ground by planetary ball mill. The ground mixture was then activated by heating for various times and washed for removal of excess succinic anhydride. The ground mixtures and the heat-activated mixtures were...

Two methods of investigation were used to evaluate the heat quantity associated with anabolic processes (qan) during the aerobic growth of Escherichia coli in a minimal medium containing succinic acid as the sole energy and carbon source. The study of the contribution of biosynthetic reactions from succinic acid and ammonia were investigated by both methods. The two qan values obtained were in ...

Esterification of inorganic phosphate accompanies the oxidation of succinic acid by cell-free extracts of E. coli. Inorganic phosphate appears to be an essential requirement for the dehydrogenation of the C(4)-dicarboxylic acid.

The proventricular surface epithelial cells were positive for both acid and neutral mucins and stained intensive for acid phosphatase and adenosine triphosphatase. The proprial gland cells revealed histochemical distribution and activity of various enzymes and lipids similar to that of the submucosal gland cells. However, the ductular cells of the submucosal glands showed comparatively stronger...

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 ...

A new batch calorimeter was used to study the aerobic growth of Escherichia coli in a minimal containing a growth-limiting concentration of succinic acid. The shape of the thermograms obtained was simple when the energy source was the only growth-limiting factor and showed a stationary phase when the oxygen transfer was limiting. The experimentally determined value of the heat production during...

Clinical disorders known to affect inherited gamma-amino butyric acid (GABA) metabolism are autosomal recessively inherited succinic semialdehyde dehydrogenase and GABA-transaminase deficiency. The clinical presentation of succinic semialdehyde dehydrogenase deficiency includes intellectual disability, ataxia, obsessive-compulsive disorder and epilepsy with a nonprogressive course in typical ca...

When adult worms of the acanthocephalan parasite, Polymorphus minutus, are incubated for 4 hr. at 417 ±0-5° C. under near-anaerobic conditions in a balanced salt solution containing radioactive glucose, they excrete two substances which contain approximately equal amounts of radioactivity. It was suspected that these metabolites might be organic acids. They were found to be non-volatile, dialys...
