The headgroup conformation of phospholipids in membranes.
Georg Büldt,Roland Wohlgemuth +1 more
TL;DR: Considering lipid influence on membrane protein function, the work of Overath, Schairer and Stoffel (1970) gives an example of the way in which the lipid state influences sugar transport through membranes of Escherichia coli which were enriched in some lipid species.

Conformation of phosphatidylethanolamine in the gel phase as seen by neutron diffraction
Georg Büldt,Joachim Seelig +1 more
TL;DR: Measurements made on 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE) in the gel phase by the same method confirm the idea that the conformation of a DPPE molecule in thegel state is very similar to the crystal structure of rac-1, 2-dilauroyl

The influence of cholesterol on head group mobility in phospholipid membranes.
John C. W. Shepherd,Georg Büldt +1 more
TL;DR: The dielectric dispersion in the MHz range of the zwitterionic dipolar phosphocholine head groups has been measured for various mixtures of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and cholesterol and in general the presence of cholesterol increases the DPPC head group mobility due to its spacing effect.

Conformational differences between sn-3-phospholipids and sn-2-phospholipids: A neutron and X-ray diffraction investigation
Georg Büldt,Gerard H. de Haas +1 more
TL;DR: In this article, the authors showed that the C(1)C(3) vector of the glycerol backbone part is oriented parallel to the bilayer surface and the 2H nuclear magnetic resonance signals indicate that both chains have a conformation similar to that observed for the bent chain in sn-3-phospholipids.

A new approach for using labels in small-angle scattering experiments.
TL;DR: This paper demonstrates a simple procedure by which additional information can be obtained from the small-angle scattering curve of a molecule which contains a small label of enhanced scattering power, which gives amore direct information about different aspects of the structure.
