Conformational analysis of lecithin in vesicles by 13C NMR

13C Fourier transform nuclear magnetic resonance. XII. Structure of the phytol–lecithin bilayer. Application of electric field effects

“…Assign-phytol dispersed in D 2 0 by sonication with the ments were taken from those made by Batchelor addition of 2mol% SDS, and for phytol inet 01. (10) and by comparison with 13C chemical corporated into the bilayer. The phytol 13C shifts of a series of fatty acids and their methyl assignments are taken from Goodman et al (12).…”

Nuclear Magnetic Relaxation and the Biological Membrane

“…The l3C chemical shifts of the fatty acid chains in sonicated aqueous dispersions of egg yolk lecithin are found to be slightly temperature dependent, and have been interpreted in terms of conformational changes in the chain (Batchelor et al, 1972).…”

Magnetic resonance of membranes

“…For 31p, the chemical shifts are characteristic of the different lipid species and can be utilized in the quantitative analysis of the lipid composition of sonicated vesicles or detergent-solubilized membranes (see Table 1). In addition, 13C chemical shifts provide an aid to conformational analysis, for example of the lipid chains (Batchelor et al, 1972). 13C T1 relaxation time measurements also provide valuable information on segmental molecular dynamics (Lee et al, 1976), benefitting both from the higher resolving power of "C n.m.r.…”
