The infrared spectra of aqueous dispersions of a homologous series of symmetric-chain, disaturated phosphatidylcholines, with fatty acyl chain lengths ranging from 12 to 19 carbons, have been measured at comparable reduced temperatures in their liquid-crystalline phases. The infrared spectra of these compounds contain bands that are dependent on the conformation of the fatty acyl chains. In particular, in the 1400-1300-cm-1 spectral region, there are bands due to CH2 wagging which are specific… Expand

Acyl chain conformational ordering in liquid-crystalline bilayers: comparative FT-IR and 2H-NMR studies of phospholipids differing in headgroup structure and chain length
AbstractFT-IR spectroscopy has been used to evaluate the acyl chain conformational ordering of DMPC, DMPE, DMPA (pH 6 and 12), DMPG (pH 1 and 7), and DPPC, DPPE, DPPA (pH 6). The frequencies of theExpand
Conformational disorder in unsaturated phospholipids by FTIR spectroscopy.
TLDR
Conformational disorder in liquid alkenes and in the L alpha and Hparallel phases of some unsaturated phospholipids has been monitored by FTIR spectroscopy and difficulties in quantitative determination of conformational Disorder in unsaturated chains are discussed. Expand
Studies of highly asymmetric mixed-chain diacyl phosphatidylcholines that form mixed-interdigitated gel phases: Fourier transform infrared and 2H NMR spectroscopic studies of hydrocarbon chain conformation and orientational order in the liquid-crystalline state.
TLDR
2H-NMR studies of the specifically chain-perdeuterated analogs of these asymmetric-chain lipids reveal that the orientational order parameter profiles of their shorter and longer chains differ both qualitatively and quantitatively, regardless of whether they are esterified at the sn1- or sn2 positions of the glycerol molecule.

Conformation of phosphatidylcholine in neat and cholesterol-containing liquid-crystalline bilayers. Application of a novel method.
TLDR
Analysis of the intramolecular pyrene-pyrene collision data obtained for 30 phosphatidylcholine species in terms of a simple geometrical model showed that addition of 50 mol % cholesterol had only a small effect on the penetration difference of the acyl chains, strongly suggesting that the conformation of phosphate in the liquid-crystalline state is determined largely by intramolescular, rather than intermolecular, interactions.

Temperature-Dependent Hydrocarbon Chain Disorder in Phosphatidylcholine Bilayers Studied by Raman Spectroscopy.
TLDR
Temperature onset of the decrease of Raman intensity of the asymmetrical methylene stretching band is the same for unsaturated lipids (DLPC, POPC, and DOPC), which was interpreted as the importance of packing defects in the bilayers of these phospholipids. Expand

Quantitative determination of conformational disorder in the acyl chains of phospholipid bilayers by infrared spectroscopy.
TLDR
A method is proposed and demonstrated for the direct determination of conformational disorder (trans-gauche isomerization) as a function of acyl-chain position in phospholipid bilayer membranes with significant advantages of the FT-IR approach. Expand
A differential scanning calorimetric study of the thermotropic phase behavior of model membranes composed of phosphatidylcholines containing linear saturated fatty acyl chains.
TLDR
The thermotropic phase behavior of a series of 1,2-diacylphosphatidylcholines containing linear saturated acyl chains of 10-22 carbons was studied by differential scanning calorimetry and indicated that the kinetic limitations become more severe as the length of the acyl chain increases. Expand
Lecithin bilayers. Density measurement and molecular interactions.
TLDR
The consistency of these calculations supports the conclusion that the most important molecular energies for the main transition in lecithin bilayers are the hydrocarbon chain interactions and the rotational isomeric energies, and that the main phase transition is analogous to the melting transition in the alkanes from the hexagonal phase to the liquid phase, but with some modifications.

TLDR
The physical properties of bilayers of dipalmitoyl-3-sn-phosphatidylcholine are analyzed in terms of a statistical model proposed by Marcelja, which yields the probabilities of trans and gauche conformations and also those of more specific conformational defects like kinks or jogs. Expand
