Abstract
The composition of the fatty acids of green algae Ulva intestinalis living in the small rivers of the pool of the lake Elton was investigated. It is established that the basic fatty acids are acids with a long chain of 16 and 18 carbon atoms. The variability of the structure of fatty acids of lipids of U. instenstinalis depending on the factors of environment - level of mineralization, temperature, saturation by oxygen, acidity of environment - was investigated. It was revealed that unsaturation of fatty acids increases with an increase in water mineralization. Participation ω6 and ω3 desaturases in the adaptation of U. intestinalis to this factor is assumed.
