In this study, examines oil percentage and fatty acid composition of Silybum marianum seeds were determined in habitats located in the west of Mazandaran province at different elevations and soil physiochemical properties. After identifying Silybum marianum shrubs in elevation classes of the study area, seeds were sampled using systematic random method and along a 100 m transect at 30 m interva...
Reports from this laboratory have described the formation of palmitoleic and oleic acids from their saturated counterparts by enzyme systems of yeast (2, 3). For introducing a double bond into the 9,lO position of the aliphatic chain, the desaturating enzymes, acting on the coenzyme A derivatives of the fatty acids, require reduced triphosphopyridine nucleotide, and molecular oxygen as hydrogen...
Lipoxygenase from the germ of corn, Zea mays, oxidized linoleic acid to primarily 9-D-hydroperoxy-trans-lO,cis-12octadecadienoic acid.
1. The effect of concentration on the oxidation and incorporation into lipids of lauric acid and linoleic acid by rings of rat small intestine has been studied in vitro. 2. In the absence of glucose, the oxidation of lauric acid in the range 0.01-5.0mm showed a maximum at 0.1mm. In the presence of glucose the maximum was at 0.5mm. The oxidation of linoleic acid in the presence of glucose increa...
The driving force behind most conjugated linoleic acid (CLA) research in swine has been related to potential improvements in animal production. Early work that used rodent models indicated that feeding CLA could potentially reduce body fat, increase lean content, increase growth rate, and improve feed conversion efficiency. Producer-backed funding organizations were, therefore, receptive to pro...
An article we wrote for the 1998 Illinois Dairy Report (Can Milk Fat be Beneficial to Your Health?) provided a brief description of conjugated linoleic acid (CLA), a minor component of milk fat. Briefly, CLA is a fatty acid that is synthesized in the rumen during biohydrogenation of linoleic acid (C18:2), the predominant fatty acid in vegetable oils. The pathway of biohydrogenation is C18:2 ? C...
Brassica napus leaves developed at low temperature display rapid in situ desaturation of monogalactosyldiacylglycerol (MGDG) fatty acids leading to the production of hexadecatrienoic/linolenic acid. This was shown by radioactivity-tracer experiments to occur via a sequence of desaturations proceeding from the initially synthesized palmitic/oleic acid molecular species to palmitic/linoleic acid,...
The effect of the long chain keto acid, which is one of the secondary products from oxidative deteriolation of lipids, on the enzyme activity was investigated in vitro. Cholinesterase and succinate dehydrogenase were inhibited more effectively by 12-keto oleic acid than by linoleic acid, whereas the inhibition of trypsin by linoleic acid was greater than that caused by 12-keto oleic acid. This ...
Soluble soybean polysaccharide (SSPS) was fractionated into its low- (LMW) and high-molecular-weight (HMW) components to test their antioxidative and emulsifying properties. Linoleic acid was emulsified with an aqueous solution of SSPS, HMW, a mixture of LMW or HMW with maltodextrin, or maltodextrin alone. The emulsions prepared with SSPS, HWM and the mixture of HMW with maltodextrin were stabl...
The effect of oleic, linoleic and γ-linolenic acids on ROS production by 3T3 Swiss and Rat 1 fibroblasts was investigated. Using lucigenin-amplified chemiluminescence, a dose-dependent increase in extracellular superoxide levels was observed during the treatment of fibroblasts with oleic, linoleic and γ-linolenic acids. ROS production was dependent on the addition of β-NADH or NADPH to the medi...
