[RASMB] PSV of Phosphatidylethanolamine

[pjgb at mrc-lmb.cam.ac.uk]

Dear RASMBers,

Does anyone know a reliable partial specific volume for the E. coli polar 
phospholipids?
These are largely phosphatidylethanolamine (PE) and phosphatidylcholine 
(PC), with the latter in major abundance, and they contain mostly C16 and 
C18:1 fatty acids.

I have so far managed to run one useful reference to ground - a paper by 
Tenchov et al. (BBA 1417, 183-190, 1999), in which they give a plot of PSV 
against temperature for PE with C16 fatty acid, measuring it by the Kratky 
method of density differences - but I wondered whether anyone knows of any 
other useful work on this topic.  Please feel free to mention your own 
work, if relevant.

Thanks in advance,

Jo
