Ammonium glycolate combustion was used to synthesize SrZr0.95Y0.05O3−x powders. Soluble metal-glycolate complexes, detected by infrared spectroscopy, were formed with Y+3 and Zr+4, which maintain atomic level mixing of metal cations with glycolic acid. Sr+2/glycolic acid mixtures did not form glycolate complexes. Temperature-programmed reaction studies showed that only precursor solutions with ...

Oxidation of glycolate to 2 CO2 and 3 H2 (delta G degrees' = +36 kJ/mol glycolate) by the proton-reducing, glycolate-fermenting partner bacterium of a syntrophic coculture (strain FlGlyM) depends on a low hydrogen partial pressure (pH2). The first reaction, glycolate oxidation to glyoxylate (E zero' = -92 mV) with protons as electron acceptors (E zero' = -414 mV), is in equilibrium only at a pH...

Formation of d-phosphoglycerate, glycolate, glycerate, and serine by tobacco leaves was analyzed between 4 and 60 set of 14C02 fixation during photosynthesis. With decreasing time, the percentage of the total 14C incorporated into 3phosphoglycerate increased; the percentage into the other compounds, including glycolate, decreased to nearly zero. At 4 or 11 set 3-phosphoglycerate and glycerate w...

In the title mol-ecular salt (systematic name: morpholinium 3-hy-droxy-2,4,6-trinitro-phenolate), C(4)H(10)NO(+)·C(6)H(2)N(3)O(8) (-), two of the nitro groups of the anion are close to parallel with the plane of the benzene ring [dihedral angles = 3.46 (9) and 11.60 (10)°] and one is almost perpendicular [dihedral angle = 82.23 (8)°]. An intra-molecular O-H⋯O hydrogen bond occurs in the anion. ...

BACKGROUND Glycolate is a valuable chemical with extensive applications in many different fields. The traditional methods to synthesize glycolate are quite expensive and toxic. So, the biotechnological production of glycolate from sustainable feedstocks is of interest for its potential economic and environmental advantages. D-Xylose is the second most abundant sugar in nature and accounts for 1...

Oxalate synthesis in human hepatocytes is not well defined despite the clinical significance of its overproduction in diseases such as the primary hyperoxalurias. To further define these steps, the metabolism to oxalate of the oxalate precursors glycolate and glyoxylate and the possible pathways involved were examined in HepG2 cells. These cells were found to contain oxalate, glyoxylate, and gl...

Bacterium T-52, cultured on ethylene glycol, readily oxidized glycolate and glyoxylate and exhibited elevated activities of ethylene glycol dehydrogenase and glycolate oxidase. Labeled glyoxylate was identified in reaction mixtures containing [C]-ethylene glycol, but no glycolate was detected. The most likely pathway of ethylene glycol catabolism by bacterium T-52 is sequential oxidation to gly...

Human red cells manifest glycolate kinase activity. This activity copurifies with pyruvate kinase and is decreased in the red cells of subjects with hereditary pyruvate kinase deficiency. Glycolate kinase activity was detected in the presence of FDP or glucose-1,6-P2. In the presence of 1 mmol/L FDP, the Km for adenosine triphosphate (ATP) was 0.28 mmol/L and a half maximum velocity for glycola...

Glycolate was excreted from the 5% CO(2)-grown cells of Euglena gracilis Z when placed in an atmosphere of 100% O(2) under illumination at 20,000 lux. The amount of excreted glycolate reached 30% of the dry weight of the cells during incubation for 12 hours. The content of paramylon, the reserve polysaccharide of E. gracilis, was decreased during the glycolate excretion, and of the depleted par...

Phosphoglycolate and phosphoglycerate phosphatases and glycolate dehydrogenase activities were determined in division synchronized Euglena gracilis strain Z cultures. Phosphoglycolate phosphatase activity remained nearly constant in the light but doubled in the dark, whereas phosphoglycerate phosphatase activity decreased by half in the light and increased 4-fold over the dark phase of the cycl...
