  • Fatty Acid Composition of Spirulina and spirulina -like cyanobacteria in relation to their chemotaxonomy
    Phytochemistry, 1991
    Co-Authors: Zvi Cohen, Avigad Vonshak

    Abstract:

    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.

  • Influence of Diet on Fatty-Acid Composition of Depot Fat in Western Sandpipers (Calidris Mauri)
    The Auk, 2003
    Co-Authors: Oliver Egeler, Dana Seaman, Tony D. Williams

    Abstract:

    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).
