Perdeuterated palmitic acid was intercalated into the human erythrocyte membrane and its motion studied by deuterium nuclear magnetic resonance (2H-NMR). From analysis of temperature dependent changes in the 2H-NMR spectra and from an analysis of derived moments we conclude that the acyl chains of the erythrocyte lipids do not exhibit a detectable phase transition.
