The oxidation and turnover of plasma glycerol has been studied in lean and obese, fed and starving man by means of a long-term infusion of glycerol-(14)C, and the participation of glycerol in gluconeogenesis has been determined. Under none of the experimental conditions did glycerol contribute more than 10% of the total respiratory CO(2). Glycerol turnover in fed lean subjects was 106 mmoles/mi...

Rainbow smelt is a small fish that accumulates glycerol in winter as a cryoprotectant when the animal is in seawater. Glycerol is synthesized in liver from different substrates that all lead to the formation of glycerol-3-phosphate (G3P). This study assesses whether glycerol is produced by a direct dephosphorylation of G3P by a phosphatase (G3Pase) or by a cycling through the glycerolipid pool ...

We report, in this work, our study of the thermal conductivity high-viscosity nanofluids based on glycerol. Three have been prepared with different contrasts, by suspending graphene flakes, copper oxides, or silica nanoparticles pure The were thermally characterized at room temperature 3ω technique, low amplitudes oscillations. A significant enhancement is found both glycerol/copper oxide and g...

The superior quality of glycerol synthesized.from propylene (Groll, et al., 1938; Williams, 1938, 1941), as compared with glycerol obtained from fats and oils, has been reported by Williams (1938) and confirmed by studies in pharmacology (Hart, 1939) and experiments in histology (Nichols, 1941). Since glycerol is a constituent of numerous culture media for microorganisms, the value of synthetic...

legumes are rich sources of protein and consider a good alternative to make a protein films. in this study, central composite design to investigate the simultaneously effect of the grasspea protein isolates (2 - 10 percent), glycerol (0.5 - 7%) and oleic acid (0 - 2%) on properties of edible films made from grasspea protein isolates, such as thickness, density, percentage of solubility in water...

lipase from candida antarctica, fixed on macroporous acrylic resin, has been used for the intermediate production of mono- and diolein by hydrolysis of triolein. the effect of altering concentrations of triolein and glycerol and the function of the molecular sieve on the hydrolysis reaction of triolein were investigated. the highest hydrolysis yield was observed for the utmost concentration of ...

abstract. seeds or plant organs are usually used as the materials for the long-term cryopreservation. the aim of this study is to investigate the possibility of seed cryopreservation of lilium ledebourii (baker) boiss. as an endemic and endangered species because of genetic erosion. to evaluate seed potentials for the cryopreservation, four treatments including vitrification, 30% glycerol, desi...

The etherification of glycerol with propylene over acidic heterogeneous catalysts, Amberlyst-15, S100, and S200 resins, produced mono-propyl glycerol ethers (MPGEs), 1,3-di- and 1,2-di-propyl glycerol ethers (DPGEs), and tri-propyl glycerol ether (TPGE). The propylation of glycerol over Amberlyst-15 yielded only TPGE. The glycerol etherification with 1-butene over Amberlyst-15 and S200 resins p...

Rates of phosphatidate synthesis from dihydroxyacetone phosphate via acyl dihydroxyacetone phosphate or glycerol phosphate are compared in homogenates of 13 tissues, most of which are deficient in glycerol phosphate dehydrogenase (EC 1.1.1.8). In all tissues examined, dihydroxyacetone phosphate entered phosphatidate more rapidly via acyl dihydroxyacetone phosphate than via glycerol phosphate. T...

Experiments were designed to determine when, during the cryopreservation process, sperm lose fertilizing capacity and whether the cryoprotectant, methyl cellulose (MC), could be used in combination with glycerol to cryopreserve sperm and remain in the inseminate without reducing fertility. Semen diluted in Minnesota Avian extender (MNA) and inseminated immediately had greater fertility (75%) th...
