K. Sengupta et al., Structure of the ripple phase in chiral and racemic dimyristoylphosphatidylcholine multibilayers, PHYS REV E, 59(2), 1999, pp. 2455-2457
We present electron density maps of the ripple phase of chiral and racemic
dimyristoylphosphatidylcholine. The structures of the two systems are found
to be identical within experimental errors, thus unambiguously showing tha
t the chirality of the lipid molecules does not influence the structure of
this phase.
