Highly schematic representations of the liquid-crystalline LDL core (cross-sectional views). &dcl001; Phospholipids; &dcl002; Cholesteryl esters; &dcl003; Apo B. Free cholesterol and triacylglycerols have been omitted from the drawings for clarity A: Generalized representation of earlier models (19–25). In these models, the LDL particle is spherical and the liquid-crystalline core is organized in concentric shells of cholesteryl esters. B: Generalized representation of new models (32,35,36), in which the liquid-crystalline core contains flat layers of cholesteryl esters.
