Cholesterol interactions with phospholipids in membranes.
Mammalian cell membranes are composed of a complex array of glycerophospholipids and sphingolipids that vary in head-group and acyl-chain composition. In a given cell type, membrane phospholipids mayExpand

Membrane properties of sphingomyelins
Sphingomyelin and phosphatidylcholine are important components in the external leaflet of cellular plasma membranes. In this review we compare the structure of these lipid molecules, with emphasis onExpand

Rhizavidin from Rhizobium etli: the first natural dimer in the avidin protein family.
Rhizobium etli CFN42 is a symbiotic nitrogen-fixing bacterium of the common bean Phaseolus vulgaris. The symbiotic plasmid p42d of R. etli comprises a gene encoding a putative (strept)avidin-likeExpand

Interaction of cholesterol with sphingomyelins and acyl-chain-matched phosphatidylcholines: a comparative study of the effect of the chain length.
In this study we have synthesized sphingomyelins (SM) and phosphatidylcholines (PC) with amide-linked or sn-2 linked acyl chains with lengths from 14 to 24 carbons. The purpose was to examine how theExpand

Hepatocellular uptake of 3H-dihydromicrocystin-LR, a cyclic peptide toxin.
The cellular uptake of microcystin-LR, a cyclic heptapeptide hepatotoxin from the cyanobacterium Microcystis aeruginosa, was studied by means of a radiolabelled derivative of the toxin.Expand

Cyclodextrin-mediated removal of sterols from monolayers: effects of sterol structure and phospholipids on desorption rate.
In this study, we have examined a number of parameters which affect the rate of sterol desorption from a model membrane surface (a monolayer at the air/water interface) to cyclodextrins (CD) in theExpand

Interaction of cholesterol with sphingomyelin in monolayers and vesicles.
To understand the structural basis for the apparent strong interaction between cholesterol and sphingomyelin (SPM), we have synthesized an analogue of SPM, 3-deoxy-2-O-stearoyl-SPM, in which anExpand

Membrane properties of D-erythro-N-acyl sphingomyelins and their corresponding dihydro species.
We have prepared acyl chain-defined D-erythro-sphingomyelins and D-erythro-dihydrosphingomyelins and compared their properties in monolayer and bilayer membranes. Surface pressure/molecular areaExpand

A calorimetric study of binary mixtures of dihydrosphingomyelin and sterols, sphingomyelin, or phosphatidylcholine.
The thermotropic properties of binary mixtures of D-erythro-n-palmitoyl-dihydrosphingomyelin (16:0-DHSM), D-erythro-n-palmitoyl-sphingomyelin (16:0-SM), cholesterol, lathosterol, andExpand
