Abstract: | Dynamics of fatty acid composition of total lipids was studied for freshwater salmon Salmo salar L. during its embryonic development from blastula (3 hours) up to hatching (108 days) as well as in unfertilized eggs. Stable
amount of total and some saturated, monounsaturated and polyunsaturated fatty acids (PUFA) of total lipids was observed during
embryonic development. Considerable changes in fatty acid composition were observed at the stage of prelarvae hatching, i.e.,
significant decrease of (n-6) PUFA (18:2(n-6) and 20:4(n-6)) and (n-3) PUFA and increase of total and some saturated and monounsaturated
fatty acids was registered. Change in saturation ratio of membrane lipids justifies the presence of the biochemical mechanism
forwarded on regulation of cell membrane enzymes in accordance with the changes of internal physiological processes taking
place in the organism and fluctuations of external environmental conditions or the preparation period (as reproduction). Data
on peculiarities of transformation and utilization of fatty acids during salmon embryonic development may be used for understanding
of their functional role in the developing organism as well as for assessing the quality of the caviar. |
