Abstract : Several lipide protein complexes were investigated by the empirical 'group frequency' method of qualitative IR structural analysis by obtaining, interpreting, comparing and correlating the IR spectra of the complexes and several related and constituent compounds. The major absorption bands of the complexes, related and constituent compounds, showed that the complexes contained all of the lipides examined in this study. By IR techniques the qualitative structural analysis of the lipide protein complexes was confirmed. Cerebrosides was the most abundant lipide and sphingomyelin the least abundant lipide found in this series of complexes. Each of the major absorption bands in the NaCl region was interpreted and possible group vibrational assignments made. Possible assignment of group vibrations to the major absorption bands in the far IR region were not made. The broad band IR spectra of the various compounds confirmed and complimented the structural analysis obtained from an interpretation of the NaCl region spectra. Extensive experimental work was done in the development of a suitable sampling technique. (Author)
