TL;DR: In this article, structural analysis, a purification scheme and stability information on a fluorescent cholesterol analogue, which has been used as a probe in several model and biological systems, are presented.

TL;DR: The transfer protein isolated from bovine brain transferred several different neutral glycosphingolipids and ganglioside GM1 equally well, but failed to accelerate phosphatidylcholine or sphingomyelin intervesicular movement.

TL;DR: Dehydroergosterol has been widely used as a fluorescent analog of cholesterol for the investigation of lipoprotein, model membrane, and biological membrane structure as discussed by the authors, but the complete structure and assignment of the three double bonds in the rings has not yet been firmly established.

TL;DR: These inhibitory effects depend upon an intact disulfide ring, since the ability of N-ethylmaleimide-reacted oxytocin to inhibit insulin-stimulated processes was reduced by more than 90% when compared to the intact molecule.

TL;DR: It is suggested that the reduced rate is caused by a reduction in the number of productive collisions rather than by a slow rate of penetration of the membrane-binding domain into the bilayer.
