“…3). Indeed, LDL-and, to a much lesser extent, HDL-associated lipids make substantially greater contributions to the line-shape and intensity of the composite SF lipoprotein fatty acid acyl chain terminal-CH, and bulk (-CH,-), resonances at higher temperatures than they do at lower ones, a phenomenon attributable to the core cholesterol esters of these lipoproteins undergoing an order-disorder phase transition throughout this temperature range [8]. The corresponding signals of the triacylglycerol-rich chylomicron and VLDL particles do not undergo this phase transition, consistent with their core lipids being in a liquid-like state at temperatures 2 20°C.…”
