The present study was conducted to evaluate the effect of low-dose gamma irradiation (0, 1, 3 and 5 kGy) on fatty acid composition of Rainbow trout (Oncorhynchus mykiss) fillet. Among all of the fatty acids, oleic acid (C18:1) (with mean 33.50±3.02 g/100 g fatty acids) and myristoleic acid (C14:1) (with mean 0.41±0.26 g/100 g fatty acids) were the most predominant and the lowest fatty acids in ...

Euglena gracilis was grown in the dark for 12 days. Subsequent incubation with sodium octanoate-l-14C in the dark for 6 hours resulted in a rather specific incorporation of radioactivity into the neutral lipids (primarily wax esters). Upon illumination of these cells in an identical medium without radiocarbon, the radioactivities in the neutral lipids decreased strongly, due to a decrease of th...

Lipid bodies, nonmembrane-bound cytoplasmic inclusions, serve as repositories of esterified arachidonate and are increased in cells associated with inflammatory reactions. We have evaluated stimuli and mechanisms responsible for lipid body formation within human polymorphonuclear leukocytes (PMNs). Arachidonic acid and oleic acid stimulated dose-dependent formation of lipid bodies over 0.5-1 h....

The present contribution investigates the biocatalytic performance of lipase obtained from latex native plant known as Araujia sericifera (ASL) in hydrolysis followed by esterification released free fatty acids and transesterification glycerides sunflower waste cooking oil WCO. A specific enzymatic activity 719.05 ?mol mg?1 h?1 (60 % conversion triglycerides towards acids) was WCO with 0.05 bio...

Background and Objectives: Breast milk composition is affected by several factors such as maternal diet and body mass index. Milk fats include a major calorie content of the milk, which changes dramatically throughout the lactation. The aim of the present study was to assess breast milk fatty acid profile in overweight and obese mothers and its correlations with maternal body mass index. Mater...

The mono-, di-, and triphosphoinositides of bovine brain were isolated by chromatography on columns of DEAE-cellulose, alumina, and silicic acid. The major molecular species in each phosphoinositide class were identified and quantitatively estimated by combined thin-layer and gas-liquid chromatography of the component diglycerides, which were released by hydrolysis with a specific brain phospho...

A column chromatographic procedure utilizing Silica Gel C is described for separating lipid components of serum and lipoproteins into individual fractions containing hydrocarbons (I), cholesterol esters (II), triglycerides (111), cholesterol (IV) , free fatty acids (V) , and phospholipids (VI). Silica Gel G required no pretreatment except adjustment of moisture content to 10%. The method afford...

For a long time, the perception of consumers about fat from animal origin was linked to the increased risk of cardiovascular diseases, especially due to the large amounts of saturated fatty acids. The dairy products provide 15 to 25% of fat consumed by humans and 25 to 35% of saturated fat (Chilliard et al., 2001). This statement of cognizance, even if the potential effects of saturated fatty a...
