New chemical kinetic reaction mechanisms are developed for two of the five major components of biodiesel fuel, methyl stearate and methyl oleate. The mechanisms are produced using existing reaction classes and rules for reaction rates, with additional reaction classes to describe other reactions unique to methyl ester species. Mechanism capabilities were examined by computing fuel/air autoignit...
Essential fatty acid (EFA) status was assessed in 15 Southern Thai preschool children. The mean (+/- SD) serum linoleate (18:2 n-6), arachidonate (20:4 n-6), linolenate (18:3 n-3), eicosapentaenoate (20:5 n-3), and docosahexaenoate (22:6 n-3) percentages in the preschool children were 21.7 +/- 4.0, 6.0 +/- 1.2, 0.4 +/- 0.1, 1.2 +/- 0.8, and 4.4 +/- 1.3, respectively. Since EFA composition of to...
The inhibition of several enzyme activities by free fatty acids has been examined. The inhibition of rat liver microsomal linolenate-activating enzyme activity by linolenate was found to be due to the inactivation of enzyme by substrate fatty acid. Stearoyl coenzyme A was also found to inhibit linolenate-activating enzyme. Likewise, microsomal glucose 6-phosphatase was inhibited by oleate; the ...
flammatory compound. Compound 1 suppressed 12-Otetradecanoyl-phorbol-13-acetate (TPA)-induced infiammation on mouse ears at a dose of 500vg (the i"hibitory effect (IE) was 43%). Linolenic acid methyl ester did not inhibit this infiammation at the same dose. Howeyer, the related compounds of 1, (9Z,11E)-13hydroxy-9,11-octadecadienoic acid (5) and (9Z,11M13-oxo-9,11-octadecadienoic acid (6), slto...
To explain the unusually high selectivity of copper catalysts toward linolenate, model compounds were hydrogenated (150 C and atmospheric pressure) and the reaction products analyzed. Products varied depending upon location of the double bonds. Monoenes were not reduced by copper chromite except when the double bond was next to a carboxyl group. Dienes with isolated double bonds also were not r...
The fruits of Withania coagulans Dunal (family: Solanaceae) are sweet, sedative, emetic, alterative and diuretic; used to treat asthma, biliousness, strangury, wounds, dyspepsia, flatulent colic, liver complaints and intestinal infections. Phytochemical investigation of the fruits yielded a withanolide tetraglucoside identified as (20S, 22R)-5alpha, 20alpha-diacetoxy-6beta-hydroxy- 1-oxowitha-2...
