Аннотация

In this report, we study lipid components (fatty acids with various degrees of unsaturation, aldehydes and sterols) of deep-water sponges Baikalospongia intermedia profundalis sampled using deep-water manned submersibles Mir at depths of 150-1520 meters for the first time. It was found that unsaturated fatty acids predominate in the fatty acid composition of the sponges: very long chain demospongic acid 26:3, as well as monounsaturated 24:1 and isomers of acids 16:1 and 18:1. Among the saturated fatty acids myristic 14:0, palmitic 160 and stearic 18:0 acids are predominate. In addition significant amounts of acids of microbial origin (iso-palmitic i16:0, isostearic i18:0, oxy-stearic 10h18) were detected.
