Notes:
The 1H (500 MHz), 13C (300 MHz) and 31P (202 MHz) NMR spectra of rac-2,3-bis(palmitoyloxy)propyl(2-trimethylarsonioethyl)phosphonate were recorded in CDCl3 (3 M) solution. Homonuclear 1H-1H and heteronuclear 13C-1H chemical shift correlation experiments (COSY) were performed. All resonances were assigned. The shifts of the arsenic-containing phosphonolipid were compared with the shifts of the N-containing phospholipids. The most significant shift differences were found for the groups directly bonded to arsenic. Spectral evidence was indicative of free rotation about the —CH2 —CH2 —bond in the arsenocholine fragment.
