| Abstract: | The composition of fatty acids (FAs) of a green alga (Ulva intestinalis) inhabiting small rivers of the Elton Lake basin has been investigated. It has been established that long-chain FAs with 16 and 18 carbon atoms are essential. We have investigated the composition variability of FAs of lipids of U. intestinalis depending on environmental factors: the level of mineralization, temperature, oxygen saturation, and acidity. It has been revealed that FA nonsaturation increases with an increase in mineralization. We assume that ω-6 and ω-3 desaturases participate in the adaptation of U. intestinalis to this factor. |
