title: Effect of seasonal and experimental temperature on de novo synthesis of fatty acids in C. crangon.
abstract: The intensity of in vivo lipogensis was measured and in this purpose, the radioactivity of incorporation of tritium into fatty acids (FAs) in tissues of C. crangon was determined. De novo synthesis of FAs was five times higher in hepatopancreas than in muscle in summer period but not much higher in autumn. The higher FAs synthesis was recorded at 25 °C, both for hepatopancreas and muscle, and the summer was higher than the autumn in the hepatopancreas and in the muscles of the opposite situation was observed. The higher amounts of SFAs in hepatopancreas from autumn, when in experimental conditions the ambient temperature C. crangon changed from 6 °C to the experimental higher temperature. When content of PUFAn-3 declined dramatically (Autumn 1 h, 25 °C). In contrast, at a lower temperature, the amount of polyunsaturated FAs is much higher than at 25 °C (Autumn 1 h 6 °C).
