Abstract
1. 1. Lipid and phospholipid compositions of endemic freshwater sponges, belonging to the Family Lubomirskiidae, Class Demospongiae Baicalospongia bacillifera and Baicalospongia intermedia were studied. 2. 2. The fatty acids of total lipids, neutral, glyco- and phospholipid fractions were investigated by capillary gas chromatography-mass spectrometry. 3. 3. One hundred and eighty-five fatty acids were identified: 46 saturated (both iso-, anteiso-, branched, cyclic), 55 monoenoic, 37 dienoic, 25 trienoic and 22 polyenoic. 4. 4. A number of unusual fatty acids, such as br 7-12–17:1, br 9-6–17:1, c-19–26:0, and very-long-chain polyunsaturated 6,9,12,15,18,21–24:6, 15,18,21,24–30:4, and 15,18,21,24–30:5 acids, were found.
