Lipid Species

Nutritionally important PUFAs (polyunsaturated fatty acids) mediate some of their bioactivities through formation of oxygenated metabolites. These bioactive lipids are formed by COX (cyclo-oxygenase), LOX (lipoxygenase) and cytochrome-P450-catalysed reactions, as well as non-enzymatic lipid peroxidation. These reactions produce numerous species, some of which can be formed through more than one pathway. MS-based lipidomics offers the selectivity and sensitivity required for qualitative and quantitative analysis of multiple lipid species, in a variety of biological systems, and can facilitate the study of these mediators.

Long Chain

For saturated long chain fatty acids, as for hydrocarbons, the odd order "accordion mode" vibrations are Raman active. These "accordion mode" vibrations have been used to provide qualitative and quantitative analysis of mixtures of acids in the range C12–C24.
