Notizen:
The position of the branch in monomethyl branched fatty acids can be determined unequivocally by converting the fatty acid methyl esters to the corresponding branched alkanes. The mass spectra of methyl branched alkanes show intense and characteristic fragments indicating the branching points. In a parallel reaction the reduction of the methyl ester may be carried out with LiAID4 in order to label the carboxyl terminus. The applicability of this procedure is demonstrated by the identification of two isomeric branched fatty acids obtained from soya beans; with previously described methods a determination of the branching points failed.
