Table 1.

Effect of sorbic acid or decanoic acid on the ²H maximal quadrupolar splittings (in kHz) of DMPC-d₅₄ bilayers measured using static ²H solid-state NMR experiments at 35 °C

	DMPC	DMPC + 5%sorbic acid	DMPC + 10%sorbic acid	DMPC + 5%decanoic acid	DMPC + 10%decanoic acid
pH 3.0	24.0	24.4 (+1.7%)	24.8 (+3.3%)	–	–
pH 4.4	24.2	24.5 (+1.2%)	24.9 (+2.9%)	27.7 (+14.5%)	29.6 (+22.3%)
pH 6.0	24.7	24.9 (+0.8%)	25.0 (+1.2%)	–	–
pH 7.4	24.9	24.9	24.9	26.2 (+5.2%)	27.6 (+10.8%)

The values in parenthesis are the calculated percentage of increases of quadrupolar splittings upon addition of sorbic acid or decanoic acid.
