- 6 November 2007
Critical fluctuations are investigated in lipid membranes near miscibility critical points in bilayers composed of dioleoylphosphatidylcholine, chain perdeuterated dipalmitoylphosphatidylcholine, and… Expand
The preference of tryptophan for membrane interfaces.
- W. Yau, W. Wimley, K. Gawrisch, S. White
- Chemistry, Medicine
- Biochemistry
- 1 October 1998
One of the ubiquitous features of membrane proteins is the preference of tryptophan and tyrosine residues for membrane surfaces that presumably arises from enhanced stability due to distinct… Expand
Polyunsaturated docosahexaenoic vs docosapentaenoic acid-differences in lipid matrix properties from the loss of one double bond.

- Chemistry, Medicine
- Journal of the American Chemical Society
- 2 May 2003
Insufficient supply to the developing brain of docosahexaenoic acid (22:6n3, DHA), or its omega-3 fatty acid precursors, results in replacement of DHA with docosapentaenoic acid (22:5n6, DPA), an… Expand
Influence of docosahexaenoic acid and cholesterol on lateral lipid organization in phospholipid mixtures.
