Iatroscan-measured dissolved and particulate marine lipid classes in the northern Adriatic Sea

The Chromarod-Iatroscan thin-layer chromatography-flame ionization detection (TLC-FID) system was used to measure lipid classes in the dissolved and particulate fractions of seawater samples taken in the northern Adriatic Sea during winter 2008. This technigue distinguish sixteen lipid classes including hydrocarbons, wax and steryl esters, fatty acid methyl esters, fatty ketone, triacylglycerols, free fatty acids, fatty alcohols, 1, 3- and 1, 2-diacylglycerols, sterols, pigments, monoacylglycerols, mono- and di-galactosyl diglycerides, mono- and di-phosphatidylglycerols, phosphatidylethanolamines, and phosphatidylcholine. The method serve as a broad diagnostic tool for ecosystem studies, including the evaluation of components of biomembranes from living organisms, determination of caloric capacity of organic matter evaluated from compounds linked to metabolic energy reserves, and determination of the extent of degradation of organic matter by looking at lipids issued from the breakdown of glycerides in dying cells and detritus and also pollution.
