Influence of Diet on Fatty-Acid Composition of Depot Fat in Western Sandpipers (Calidris Mauri)
The Auk, 2003Co-Authors: Oliver Egeler, Dana Seaman, Tony D. WilliamsAbstract:Abstract Western Sandpipers (Calidris mauri) have been previously shown to undergo seasonal changes in the Fatty Acid Composition of their fat stores, even though they do not show the marked seasonal variation in diet common to many migratory passerines. We investigated the effect of dietary Fatty Acid Composition on the Fatty Acid Composition of adipose tissue in captive Western Sandpipers by feeding birds experimental diets with different Fatty Acid Composition. In addition, we determined the effect of total percentage of fat content of the diet (5 vs. 10%) on Fatty Acid Composition of depot fat. Birds maintained normal body mass (24–27 g) throughout all experimental treatments. Most adipose Fatty Acids were sensitive to dietary manipulation to some extent. Changes in Fatty Acid Composition of the diet had the largest effect on adipose tissue Composition for the essential polyunsaturated Fatty Acid linoleate (18:2), whereas it had the least effect for the monounsaturated Fatty Acid oleate (18:1). The saturated Fatty Acid palmitate (16:0) demonstrated an intermediate capacity to alter Fatty Acid Composition of adipose tissue. Total amount of fat in the diet did not influence the effect of diet on Fatty Acid deposition. Results of dietary manipulations in this study suggest that diet does explain some of the variation in Fatty Acid Composition observed during migration in Western Sandpipers, but that certain Fatty Acids can be modulated independently of diet (probably through de novo synthesis, postabsorption modification, or both).

Fatty Acid Composition of Spirulina and spirulina -like cyanobacteria in relation to their chemotaxonomy
Phytochemistry, 1991Co-Authors: Zvi Cohen, Avigad VonshakAbstract:The Fatty Acid Composition of several Spirulina -like cyanobacteria strains was investigated. While, on the basis of morphology alone, these strains could not be distinguished from Spirulina , their Fatty Acid Composition demonstrated a different pattern having large amounts of 18:3 (9, 12, 15), 16: 1 or 16:2, but small quantitites of -linolenic Acid. On the basis of these findings, it is suggested that Fatty Acid Composition might be utilized for the classification of Spirulina strains.

Fatty Acid Composition of serum lipids predicts the development of the metabolic syndrome in men
Diabetologia, 2005Co-Authors: Eva Warensjo, Ulf Riserus, Bengt VessbyAbstract:Aims/hypothesis Types of dietary fat have been related to components of the metabolic syndrome. Serum Fatty Acid Composition mainly reflects dietary fat intake, but also endogenous Fatty Acid synthesis catalysed by Δ-desaturases. It is not known whether alterations of Fatty Acid Composition or desaturase activities predict metabolic syndrome.
