Fatty acids of Antarctic gastropods: distribution and comparison with Mediterranean species
Fatty acids of three different lipid pools: free fatty acids (FFA), storage lipids (triglycerides and wax esters, SL) and phospholipids (PL) of mantle and viscera of Antarctic gastropods were analyzed and compared to species from the Mediterranean Sea. We analyzed specimens of the Antarctic species:...
