An internal standard for the quantification of DHA by GC- or LC-MS.

Linolein hydroperoxides are a mixture of 132 possible isomers of mono-, di-, and tri-hydroperoxides produced from the autoxidation of trilinolein. Autoxidation of linoleic acid containing triglycerides (for example, trilinolein) in vivo could result in the formation of these hydroperoxides. Unlike…
