abstract = {The specific volumes of seven
1,2-diacyl-sn-glycero-3-phosphocholines with symmetric,
unbranched acyl chains containing one, four, or six cis
double bonds per chain, or with a saturated sn-1 chain and
one, four, or six cis double bonds in the sn-2 chain were
determined by the neutral buoyancy method. Experiments were
conducted in the liquid crystalline lamellar phase over the
temperature range from 5 to 35 degrees C. It is demonstrated
that the molecular volume of phosphatidylcholines can be
well approximated as the sum of a constant volume of the
polar lipid head region and the temperature-dependent
volumes of hydrocarbon chain CH2, CH, and terminal CH3
groups. A linear dependence of chain segment volumes on
temperature was observed. A self-consistent set of partially
temperature-dependent volumes is obtained that allows
prediction of phosphatidylcholine molecular volumes within
very tight error margins.},
