Plasma lipids, lipoproteins and cell membranes.
The major plasma lipids, cholesteryl ester, triacylglycerol, cholesterol and phospholipid, are insoluble in water. They are transported in the circulation as lipoproteins-metabolically diverse macromolecules in which the various lipids are associated with specific polypeptides (the apoproteins). There are four main lipoprotein classes, defined by their size and by the density range within which...
متن کاملBiophysical properties of lipids and dynamic membranes.
The lipid bilayer is a 3D assembly with a rich variety of physical features that modulate cell signaling and protein function. Lateral and transverse forces within the membrane are significant and change rapidly as the membrane is bent or stretched and as new constituents are added, removed or chemically modified. Recent studies have revealed how differences in structure between the two leaflet...
متن کاملLateral chain packing in lipids and membranes.
The aliphatic chains of many biologically important lipids are heterogeneous and often related to the functions of the molecules. Certain phospholipids containing arachidonic acid may serve as precursors for prostaglandins, certain diglycerides may serve as second messengers for certain membrane-triggered reactions (43), and other phospholipids containing a very short chain in the two position ...
متن کاملSpectroscopic studies of lipids and biological membranes
My first interest in nuclear magnetic resonance (n.m.r.) spectroscopy began in 1964, when it seemed to me that spectroscopy, and in particular n.m.r., would be a most desirable way to analyse unknowns without smelling everything, or heating with sodium and checking for hydrogen evolution with a match (the classical A-level approach at the time). Unfortunately, I had to wait a couple of years fo...
متن کاملDynamics of lipids in synthetic membranes
Bilayer coliposomes were created from blends of head-group functionalized and non-functionalized synthetic lipids. Functionalized lipids in the outer leaflets of the bilayers were then chemically differentiated from the (unchanged) functionalized lipids of the inner leaflets, thus permitting study of the dynamics of the ensuing reequilibration that occurred via thermally activated transbilayer ...
