Zeolite catalyzed palmitic acid esterification
Microporous and Mesoporous Materials, 2018Abstract The present study compares four commercial H-Y and ZSM-5 zeolites as solid acid catalysts for the conversion of palmitic acid to methyl palmitate under smooth conditions. The palmitic acid conversion did not show a clear correlation with the amount of acid sites on the catalysts surface and depended more on the porosity and the hydrophobic ...

Palmitic Acid Kinetics in Fasting, Traumatized Patients
The Journal of Trauma: Injury, Infection, and Critical Care, 1992The contribution of free fatty acid oxidation to the elevation in energy expenditure after trauma has not been well characterized. Six control subjects and six traumatized patients were fasted for 48 hours and given a primed continuous infusion of (1-14C)palmitate to measure plasma palmitate and total free fatty acid kinetics.

Chromatographically pure galactosylceramide I3-sulfate (cerebroside sulfate (CBS)) containing palmitic acid or D-2-hydroxypalmitic acid has been prepared by the acylation of galactosylsphingosine I3-sulfate obtained from the saponification of bovine brain sulfatides.

Palmitic Acid in Early Human Development
Critical Reviews in Food Science and Nutrition, 2015Palmitic acid (16:0) is a saturated fatty acid present in the diet and synthesized endogenously. Although often considered to have adverse effects on chronic disease in adults, 16:0 is an essential component of membrane, secretory, and transport lipids, with crucial roles in protein palmitoylation and signal molecules.

[1-11C]Palmitic acid: Improved radiopharmaceutical preparation
The International Journal of Applied Radiation and Isotopes, 1982A simple synthetic procedure and processing system for the routine preparation of [1-(11)C]palmitic acid via carbonation of n-pentadecylmagnesium bromide with [11C]carbon dioxide is described. The key feature of this improved synthesis is the facile separation of the 11C fatty acid from the radiolabeled and unlabeled by-products of the Grignard ...

Cytosol binding of retinyl palmitate and palmitic acid in pigment epithelium and retina
Experimental Eye Research, 1981Abstract A 6S protein which binds [ 14 C]retinyl palmitate is present in the soluble fraction (cytosol) of the pigment epithelium but not the retina. There is no binding of [ 14 C]retinyl palmitate by the 2S retinol receptor in either the pigment epithelium or the retina. [ 14 C]Palmitic acid is bound to a peak at 6S in pigment epithelial cytosol and

Palmitic acid incorporation into the intramuscular acylglycerols in rat skeletal muscles of different fiber types was investigated at various total and unbound to albumin concentrations by means of the hind-limb perfusion technique. It was found that at simultaneously increasing total and unbound to albumin palmitic acid concentrations in the ...

Biosynthesis of Corynomycolic Acid from Two Molecules of Palmitic Acid
Nature, 1959CORYNOMYCOLIC acid, C32H64O3, m.p. 70°, [α]D = + 7.5° has been isolated from the lipids of Corynebacterium diphtheriae 1 and C. ovis 2. Its structure (III, R = H) has been established by degradation3 and confirmed by synthesis: the condensation of two molecules of methyl palmitate (I, R = CH3) in presence of NaH gives the β-ketoester (II, R = CH3 ...

Twinning in palmitic acid crystals
Journal of Crystal Growth, 1985Abstract Palmitic acid crystals are grown by slow evaporation of the solvent (methyl alcohol-acetone mixture). In addition to the elongated crystals, cross-like twins are also observed. A shift in the position of the legs in the cross-like twins is frequently observed.
