Glycine glycerophospholipids



The phosphoglyceride phosphatidyl-O-N-(2-hydroxyethyl) glycine has been isolated from the brown algae Fucus serratus (Eichenberger W et al., J Plant Physiol 1995, 146, 398).



It was shown that in that Phaeophyceae the fatty acid composition (R1 and R2) was about 80% arachidonic acid (20:4n-6) and 10% 20:5n-3. A large survey proved that this phospholipid was present in 30 different species representing the 16 orders of brown algae and in amounts of 8-25 mol% of total phospholipids. Furthermore, this lipid is very likely a specific constituent of Phaeophyceae, since it has not been observed in green algae or vascular plants so far.
