Lipid-protein interactions in the structure of mitochondrial membranes

Lipid-protein interactions in membranes.

The interactions of lipids with integral and peripheral proteins can be studied in reconstituted and natural membranes using spin label electron spin resonance (ESR) spectroscopy. The ESR spectra reveal a reduction in mobility of the spin-labelled lipid species, and in certain cases evidence is obtained for a partial penetration of the peripheral proteins into the membrane. The latter may be re...

the role of thematic structure in comprehending spoken language

in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Protein-lipid interactions on the surfaces of cell membranes.

Theoretical study of protein--lipid interactions in bilayer membranes.

An analysis is given for the perturbation of the order and composition of lipid bilayers near an intrinsic membrane protein. Two cases are examined: the protein influences the lipid order (i.e., "fluidity"), and the protein associates with one component of a lipid mixture preferentially. The order perturbation is studied as a function of temperature and lateral pressure by using Landau--de Genn...
