Bu çalışmada laurik asit (LA) oleojelatörü Span 60 ve Pluronic F68 (%10 poloksamer 188) emülgatörleriyle birlikte kullanılarak ayçiçek yağı oleojelleri geliştirilmiştir. Geliştirilen oleojellerin fizikokimyasal, termal, yapısal reolojik özellikleri belirlenmiştir. Sadece LA içeren (%20) jel oluşum zamanının %15 %5 emülgatör oleojellerden daha kısa olduğu, konsantrasyonundaki artışın yapı zamanı...

Intravenous injections of various fatty acids in rabbits caused marked thrombopenia lasting 1-2 hr. The most active saturated fatty acids were myristic acid (14:O) and lauric acid (12: 0). Activity decreased with increasing and decreasing chain length, but behenic acid (22 : 0) had, on a molar basis, activity similar to that of lauric acid. Of the unsaturated fatty acids, oleic acid (18: 1) was...

Pseudomonas putida has a variety of potential uses in bioremediation and biosynthesis of biodegradable plastics. P. putida is able to utilize a wide range of carbon sources. In this study, P. putida KT2440 was grown on glucose, glycerol, citrate, or fatty acid (lauric acid) as the sole carbon source. Differences in expression levels of genes involved in the Entner-Doudoroff pathway, glycerol me...

CYP703 is a cytochrome P450 family specific to land plants. Typically, each plant species contains a single CYP703. Arabidopsis thaliana CYP703A2 is expressed in the anthers of developing flowers. Expression is initiated at the tetrad stage and restricted to microspores and to the tapetum cell layer. Arabidopsis CYP703A2 knockout lines showed impaired pollen development and a partial male-steri...

Three diets, consisting respectively of formulations high in oleic and stearic acid, linolenic acid, and lauric acid, were fed to rats until the adipose tissue TGFA largely reflected the dietary pattern of fatty acids. The composition of the serum FFA under basal conditions and following noradrenaline-stimulated lipolysis, were examined in relation to the respective adipose tissue TGFA. It was ...

Novel mono-substituted carbohydrate fatty acid (CFA) esters and ethers were investigated for their antibacterial activity against a range of pathogenic and spoilage bacteria focussing on Listeria monocytogenes. Carbohydrate derivatives with structural differences enable comparative studies on the structure/activity relationship for antimicrobial efficacy and mechanism of action. The antimicrobi...

Diacylglycerol acyltransferases (DGAT) are involved in the acylation of sn-1,2-diacylglycerol. Palm kernel oil, extracted from Elaeis guineensis (oil palm) seeds, has a high content of medium-chain fatty acids mainly lauric acid (C12:0). A putative E. guineensis diacylglycerol acyltransferase gene (EgDGAT1-1) is expressed at the onset of lauric acid accumulation in the seed endosperm suggesting...

Bovine, human and rat serum albumins were defatted and palmitic acid, oleic acid and lauric acid added in various molar ratios. The binding of L-tryptophan to these albumins was measured at 20 degrees C in a 0.138 M salt solution at pH 7.4, by using an ultrafiltration technique, and analysed in terms of n, the number of available tryptophan-binding sites per albumin molecule, with apparent asso...

Microsomes from apical buds of pea (Pisum sativum L. var. Téléphone à rames) seedlings hydroxylate lauric acid at the omega-position. This oxidation is catalyzed by a cytochrome P-450 enzyme which differs from laurate hydroxylases previously described in microorganisms and mammals by its strict substrate specificity and the ability of low NADH concentrations to support unusually high oxidation ...
