Glycerol, a highly functionalised polyol, can be used as platform molecule to produce variety of high-value chemicals. As glycerol production is projected increase over the coming years, it’s critically important that technology and infrastructure are developed make use inevitable surplus. The catalytic ‘green’ mono alcohols from glycerol, in absence H2, an emerging area research that, recent h...

Lipid signals derived from lipolysis and membrane phospholipids play an important role in glucose-stimulated insulin secretion (GSIS), though the exact secondary signals remain unclear. Previous reports have documented a stimulatory role of exogenously added mono-acyl-glycerol (MAG) on insulin secretion from cultured β-cells and islets. In this report we have determined effects of increasing in...

Supercritical fl uid chromatography (SFC) in combination with mass spectrometric detection (MS) is a valuable technique for the determination of glycerol and mono-, di-, and triglyceride impurities at trace levels in biodiesel. The diluted biodiesel sample is analyzed without derivatization on a cyanopropyl silica column. Using MS detection in fast polarity switching positive and negative ion d...

The lipid composition of the leaves of hardy Vernal and cold-sensitive Caliverde alfalfa plants, grown at different temperatures, was determined. Phosphatidyl glycerol, phosphatidyl inositol, and the sulfolipid content were directly related to growth temperature. Mono- and digalactose diglyceride and phosphatidyl choline and ethanolamine were inversely related to temperature. At corresponding g...

The glycerolysis of methyl esters and triglycerides with crude glycerol. a coproduct from the transesterification of triglycerides, was studied. Three procedures were followed ior this conversion. The first procedure was a one-step glycerolysis with methyl esters. The second procedure was a two-step process. This proced~~re involved an initial partial glycerolysis with methyl esters, followed b...

1. A glycerol teichoic acid has been extracted from cell walls of Bacillus stearothermophilus B65 and its structure examined. 2. Trichloroacetic acid-extractable teichoic acid accounted for 68% of the total cell-wall phosphorus and residual material could be hydrolysed to a mixture of products including those characteristic of glycerol teichoic acids. 3. The extracted polymer is composed of gly...

A procedure is described for the determination of the following 19 metabolites in 200 mg gastrocnemius muscle from guinea pig: glucose 1-phosphate and 6-phosphate, fructose 6-phosphate, fructose 1,6-bisphosphate, glyceraldehyde 3-phosphate, dihydroxyacetone phosphate, 3-phospho- and 2-phosphoglyceric acid, phosphoenolpyruvate, pyruvate, glycerol, glycerol 3-phosphate, AMP, ADP, ATP, inorganic p...
