Factors Influencing the Formation and Distribution of Cholesterol Esters in Human Plasma
… importance of factors influencing the lecithin-cholesterol acyltransferase (LCAT) and lipid transfer protein (LTP) reactions in plasma. These two plasma proteins play important roles in determining the formation and distribution of cholesterol esters in plasma.

Studies on the fatty acid composition of human serum with special reference to the influence of hormones and other agents
… acids (FFA), t riglycerides, phospholipids and cholesterol esters by adsorption chromatography on a system of two columns, silicic acid and Florisil, has been elaborated for preparing samples for gas-liquid chromatographic analysis of serum lipid fatty acids.

MECHANISMS OF INTESTINAL CHOLESTEROL ABSORPTION AND TRANSPORT IN MOUSE THORACIC LYMPH DUCT LIPOPROTEINS
The metabolic fate of newly absorbed cholesterol and phytosterols is orchestrated through the sterol transporter, adenosine triphosphate-binding cassette transporter G5/G8 heterodimer (G5/G8), and the cholesterol esterifying enzyme, acyl coenzyme A:cholesterol acyltransferase 2 (ACAT2). We …

Changes in tear film biochemistry in end of day ocular discomfort with and without contact lenses
… sphingomyelins, phosphatidylserines, cholesterol esters, triacylglycerides, wax esters and free cholesterols did not change during the day, during CLs wear and they were not associated with CL comfort. C3 and C3a levels decreased during the day from morning to evening, implying that …

The study of spherical high-density lipoproteins and the intermediates involved in their formation
… contain a core of neutral lipids, mainly cholesterol esters and an outer shell of apolipoproteins, phospholipids, and cholesterol. Discoidal HDL, discovered in the plasma of patients deficient in lecithin cholesterol acyltransferase (LCAT), become spherical in morphology upon incubation …

Crosstalk between CX3CL1 and the Cytoskeleton during Vascular Inflammation
… CD36 more readily engages and internalizes cholesterol-rich, oxidized low-density lipoproteins, leading to the accumulation of cholesterol esters within macrophages, and thus, the acceleration of foam cell formation. These findings reveal a novel function of chemokines in priming macrophages …

Structure and function studies on five homogeneous reconstituted HDL complexes
… (HDL) is believed to be involved in reverse cholesterol transport. HDL consists primarily of phospholipids, cholesterol, cholesterol esters, and apolipoprotein A-I (apo A-I). However, HDL is extremely heterogeneous in size composition and the structure of its lipoprotein components, …

Structure, Assembly, and Maturation of High -Density Lipoproteins
… particles that are involved in the transport of cholesterol in the blood. They are of great importance in the treatment of coronary heart disease as low levels of HDLs are a known risk factor for the development of arteriosclerosis. Little is known about the molecular level structure of these HDL …

Flight activity and hemolymph diacylglyceride concentrations in Heliothis zea (Boddie) (Lepidoptera:Noctuidae)
… di- and triacylglycerides, free fatty acids and cholesterol. Lipids were detected with a fluorescent reagent, 1 mM 6-p-toludino-2-napthalenesulfonic acid (TNS) in 95% methanol. Detection sensitivities were 50 ng qualitatively and 500 ng quantitatively. Most male and female Heliothis zea flight …

The Role of High-Density Lipoproteins and Related Pathways in Alzheimer’s Disease
… ester transfer protein (CETP), which transports cholesterol esters and triglycerides between different lipoprotein particles. Loss-of-function mutations in CETP are associated with better cognition in aging. To investigate the role of CETP in AD, human CETP transgenic mice were crossed with an …

Characterization of native and bypass human coronary artery plaque deposits from the same heart: investigation of the chemical form of calcium in human coronary artery plaque deposits
… concentrations of carbonyl groups, typical of cholesterol esters, were similar between the native and bypass arteries. Significant signals of carbonyl groups in the crystalline and amorphous plaques were due to amino acids and proteins deposited in the plaques. Studies of 31P showed that the …

Investigating iPSC-Derived Macrophage Stimulation with Oxidised Low-Density Lipoprotein as an Effective In Vitro Model of Foam Cells in Atherosclerosis
… (oxLDLs), which are then metabolised to release cholesterol and cholesterol esters for use or recycling. Chronic uptake of modified particles eventually reduces the ability of macrophages and VSMCs to effectively break down and release the lipoprotein metabolites, causing intracellular …

A metallomic, proteomic and lipidomic investigation of the malaria parasites digestive vacuole and insights into the mediators of haemozoin formation
… found to be the dominant class comprising 90% cholesterol, 2% cholesterol esters and 0.6% acylglycerols. The detected lipids were used to prepare a model lipid blend which was found to efficiently promote β-haematin formation in yields greater than 90% in under 10 minutes and at concentrations …
