Identification and analysis of wax esters by mass spectrometry.

Abstract:

:Several ions in the mass spectra of wax esters were related to the molecular structures. Assigned structures of ions were confirmed by deuterium labeling. A simple, direct method for quantititive analyses of mixtures was developed. The method involved a comparison of sets of three ions, RCO2H(+), RCO2H2 (+) and [R'-1](+) from all compounds in the mixture. The method was found applicable for mixtures of unsaturated wax esters after reduction with tetradeuterio hydrazine.

  • Conjugated linoleic acids (CLA) as precursors of a distinct family of PUFA.

    abstract::One of the possibilities for distinct actions of c9,t11- and the t10,c12-conjugated linoleic acid (CLA) isomers may be at the level of metabolism since the conjugated diene structure gives to CLA isomers and their metabolites a distinct pattern of incorporation into the lipid fraction and metabolism. In fact, CLA appe...
