The Stereospecific Conversion of Stearic Acid to Oleic Acid.
In several enzyme systems that catalyze the desaturation of stearic acid, oleic acid (cis-Ag-octadecenoic acid) is the sole product and the reaction is therefore characterized by positional and geometrical stereospecificity. We now have found that the desaturating system of Corynebacterium diphtheriae has the further property of selectively removing 1 particular hydrogen atom from each pair of ...
متن کاملStearic acid solubility and cubic phase volume.
Stearic acid (SA) is highly soluble in structurally diverse solvents. SA/solvent packing within a (24.8 A)3 cubic volume explains the stoichiometry of SA solubility at multiple temperatures in multiple solvents. In the absence of solvent, the cubic volume contains 25 molecules at van der Waals distances from each other. At 55 degrees C, SA occupied half the cubic volume in saturated solution of...
متن کاملProviding Vegetable Stearic Acid Super V 1895 S from Hydrogenated of Crude Vegetable Stearic Acid Hcv 1895 S with a Single Fractional Distillation Column
In 2005 stearic acid V 1895 S is manufactured for 1 time in Indonesia base on the natural vegetable oil, Crude Palm Oil to apply Twin Rivers’s demand. One of it specific quality (iodine value 0.15 g/100 g maximum) is very influence to the purifying steps, one of the steps is purifying of hydrogenated crude V 1895 S (HCV 1895 S) feed by a single column of fractional distillation to produce V 189...
متن کاملPerformance of phytochemical antioxidant systems in refined-bleached-deodorized palm olein during frying.
Antioxidants are important inhibitory compounds against the oxidative deterioration of food. This study investigated the effects of various phytochemical antioxidant systems [oleoresin rosemary (OR), oleoresin sage (OS) and citric acid (CA)] on the physico-chemical characteristics of refined, bleached and deodorized (RBD) palm olein during the frying of potato chips. The effects of various mixt...
متن کاملESR studies of stearic acid binding to bovine serum albumin.
The ESR spectra of a series of chain-labelled doxyl stearic acids (5-, 7-, 12- and 16-DSA) and doxyl methyl stearates (5-, 7-, 12- and 16-DMS) bound to the high-affinity binding sites of bovine serum albumin (BSA) have been analyzed using nonlinear least-squares fitting of slow-motional ESR stimulation. The motional analysis reveals that the rotational diffusion of these stearates around the ax...
