eCite

Neutral lipid fatty acid profiles were dominated by 22:6(n-3) and palmitic acid with a significant contribution of oleic myristic stearic and vaccenic acids as well as 20:5(n-3) Seasonal changes in total lipids showed maximum accumulation in early summer and minimum levels in early winter Changes in fatty acid composition appeared related

Variation in lipid classes and fatty acid composition of

Polyunsaturated fatty acids constituted the major fatty acid class of salmon shark total liver lipid and docosahexaenoic acid (C22:6n-3) (22 7-28 4%) was the most abundant fatty acid which was significantly lower (P0 05) in winter These results suggested that lipid characteristics of salmon shark liver were influenced by season but not by

The effect of intertidal habitat on seasonal lipid

The lipid composition of blue mussels Mytilus edulis L living under different environmental conditions (in the intertidal zone and in aquaculture) was studied to detect origin-related differences in seasonal modifications of lipids and their fatty acid composition in gills and digestive glands In early May the gills and digestive glands of intertidal mussels contained higher amounts of

Influence of episodes of summer O3 on δ5and δ9 fatty acids

The fatty acid composition of membrane lipids is analyzed and the fatty acids are not first hydrolyzed important during the development of cold tolerance from separated lipid classes This is the case of many plants (Levitt 1 ^80 Bishop 1983 Kuiper unfortunately with se'eral fatty acid studies of the

Seasonal changes in lipid content and composition of the

The total lipid content varied between a maximum of 19 3% lyophilized dry weight in February (4 4% fresh weight) and a minimum of 6 6% in August (1 9% fresh weight) The major lipid classes were triacylglycerol phospholipid free sterol free fatty acid sterol ester/wax ester and alkyldiacylglycerol

Seasonal changes in phospholipid class and class

To address these inconsistencies changes in E solidaginis phospholipid composition and class-specific fatty acid composition were studied from August to November 2002 Cylindrical phosphatides mostly phosphatidylcholine (PC) increased transiently and significantly from 35% of the total to nearly 50% during the transition from freeze

Seasonal Changes in Composition of Lipid Stores in

in the fatty acid composition of these lipid stores In general fat stores in a variety of birds captured during migration are composed of many fatty acids although certain fatty acids usually predominate (McWilliams et al 2004) Specifically three fatty acids (16-carbon satu-

Handling and Storage Procedures Have Variable Effects on

Aug 01 2016It is commonly assumed that the most accurate data on fatty acid (FA) contents are obtained when samples are analyzed immediately after collection For logistical reasons however this is not always feasible and samples are often kept on ice or frozen at various temperatures and for diverse time periods We quantified temporal changes of selected FA (μg FAME per mg tissue dry weight)

Seasonal changes in phospholipid class and class

To address these inconsistencies changes in E solidaginis phospholipid composition and class-specific fatty acid composition were studied from August to November 2002 Cylindrical phosphatides mostly phosphatidylcholine (PC) increased transiently and significantly from 35% of the total to nearly 50% during the transition from freeze

Fatty Acids in Fish

Oct 14 2016The human body cannot synthesize certain fatty acids: these essential fatty acids must be consumed in the diet Fish and other aquatic foods are known to be the main sources of polyunsaturated fatty acids (PUFA) therefore humans obtain most of their eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) by consuming fish aquatic invertebrates and algae
