Representative platelet lipid NMR spectra. From this experiment, acquired at 6.5 °C, two contributions to the lipid chain methylene resonance (CH2)n are visible: centerband, 1.3 ppm (top arrow) and one spinning sideband, 8 ppm (left arrow) are shown. The internal chemical shift calibration standard, 4,4-dimethyl-4-silapentane-1-sulfonic acid (DSS) has two peaks (small arrows). HOD denotes H2O in equilibrium with D2O.
