Propionic acid has long been known (1, 2) to be a glycogenic substance in animals, but the pathway by which it is converted to intermediates of carbohydrate metabolism has remained obscure. Lorber et al. (3) demonstrated that the ~1and P-carbon atoms of propionate are randomized completely before incorporation into liver glycogen, while those of lactate are not (4). In liver slices, complete ra...

Abstract Organic- inorganic hybrid perovskite shows promising properties such as optical, electrical, and magnetic. To address issues in the standard methylammonium lead iodide toxicity stability, was replaced with Cu metal ion part iodine by chlorine anionic position. In this work, methyl ammonium copper chloride (MA 2 CuCl 4 ) phenyl ethyl (PEA were synthesised. Optical structural property va...

(R)-(+)-3,5-dinitro-N-(1-phenylethyl)benzothioamide 1 is a potential chiral solvating agent (CSA) for the spectral resolution of enantiomers via 1H NMR spectroscopy. The single enantiomer was synthesized from commercially available (R)-(+)-a-methylbenzylamine 2 in two steps with 85% yield.

Acetate and propionate, produced during colonic fermentation of unabsorbed carbohydrate, may influence systemic lipid metabolism. As a preliminary study to see whether colonic acetate is incorporated into plasma lipids and whether propionate inhibits this process, 5 healthy males were studied after fasting overnight. They were given, in random order, 12.5 mmol (1.05 g) [1,2-13C]sodium acetate b...

We have evaluated the use of [1,2-13C2]propionate for the analysis of propionic acid metabolism, based on the ability to distinguish between the methylcitrate and methylmalonate pathways. Studies using propionate-adapted Escherichia coli MG1655 cells were performed. Preservation of the 13C-13C-12C carbon skeleton in labeled alanine and alanine-containing peptides involved in cell wall recycling...

Hepatocytes isolated from sheep were incubated in the presence of reduced phenolics and glycine to determine the effects of these compounds on hepatic propionate metabolism in vitro. 3-Phenyl-propionic (PPA) or t-cinnamic (CA) acids, but not benzoic (BA) or 3-(4-hydroxyphenyl)propionic (4OHPPA) acids, decreased conversion of propionate to glucose at .05 mM in the absence of supplemental glycine...
