Migration during hydrolysis of esters of glycerophosphoric acid; the chemical hydrolysis of L-alpha-glycerylphosphoryl-choline.
In view of the biological significance of the lecithins a.nd of the fact that t;hey have been known to the chemist for a hundred years (l), it is rather surprising that there should still remain doubts concerning the position of the phosphoric acid. Until recently it has been assumed by most workers that lecithins could be hydrolyzed chemically without causing a change in the position of the ph...
متن کاملSynthesis of Propyl-Sulfonic Acid-Functionalized Nanoparticles as Catalysts for Cellobiose Hydrolysis
Functionalization of silica surfaces using organo-silanes is highly sensitive to reaction conditions. Silica-coated nanoparticles were functionalized with propyl-sulfonic acid groups (PS) under different synthesis conditions including, various solvents (Ethanol, methanol, acetonitrile, and toluene), water content in the reaction media (0% to 50%), 3-mercaptopropyl-trimethoxysilane concentration...
متن کاملThe hydrolysis of long-chain fatty acid esters of cholesterol with rat liver enzymes.
The liver plays a central role in the metabolism of cholesterol absorbed from the gastrointestinal tract. Most of this cholesterol is transported as esterified cholesterol in chylomicrons (2, 3)) by way of intestinal lymph. Recent experiments in this laboratory have demonstrated that soon after the intravenous injection into rats of chylomicrons containing labeled cholesterol esters, almost 90%...
متن کاملSulfonic Acid Group Functionalized Ionic Liquid Catalyzed Hydrolysis of Cellulose in Water: Structure Activity Relationships
Catalytic activities of eight sulfonic acid group functionalized ionic liquids in water were compared for the hydrolysis of Sigmacell cellulose (DP ~ 450) in the 150-180°C temperature range by measuring total reducing sugar (TRS) and glucose produced. The catalytic activity of acidic ionic liquids with different cation types decreases in the order imidazolium > pyridinium > triethanol ammonium ...
متن کاملHydrolysis of p-nitrophenyl esters promoted by semifluorinated quaternary ammonium polymer latexes and films.
Semifluorinated polymer latexes were prepared by emulsion polymerization of 2.5-25% of a fluoroalkyl methacrylate, 25% chloromethylstyrene, 1% styrylmethyl(trimethyl)ammonium chloride, and the remainder 2-ethylhexyl methacrylate under surfactant-free conditions. The chloromethylstyrene units were converted to quaternary ammonium ions with trimethylamine. In aqueous dispersions at particle conce...
