The phospholipid and fatty-acid compositions of nine species of higher fungi have been investigated. In the various species studied the amount of total lipids ranged from 14 to 78 mg per gram dry weight. Phosphatidylcholine and phosphatidylethanolamine were found as the main classes of phospholipids. In addition to these, phosphatidylserine, phosphatidylinositol, phosphatidylglycerol, cardiolipin and lyso derivatives of phosphatidylcholine and phosphatidylethanolamine were also found. The main fatty acids were palmitic, oleic, and linoleic, their amount in some species reaching 90%; other acids were also found, but in small amounts.

The fatty acid composition of brown algae from the Black Sea was examined. It was demonstrated that their main fatty acids were 16:0, 18:1, 18:3, 18:4 and 20:5. Examination of the glycolipid composition showed that monoglycosyldiacylglycerol content varied from 26.8 to 46.5% of total glycolipids, diglycosyldiacylglycerol content from 19.6 to 44.1%, and sulphaquinovosyldiacylglycerol content from 17.5 to 51.7%. The proportion of general lipids in various species varied from 1.2 to 4.9% and that of phospholipids from 2.9 to 19.7%. Major phospholipids were phosphatidyl choline (PC), phosphatidyl glycerol (PG) and phosphatidyl ethanolamine (PE); however, some of them were found to contain PE, PG and phosphatidyl inositol as major phospholipids but no PC. Phosphorus-containing unidentified lipids were found in certain of the species examined.
