Bilayer polarity and its thermal dependency in the e(o) and e(d) phases of binary phosphatidylcholine/cholesterol mixtures [PDF]
, 2007 Diverse variations in membrane properties are observed in binary phosphatidylcholine/cholesterol mixtures. These mixtures are nonideal, displaying single or phase coexistence, depending on chemical composition and other thermodynamic parameters.

Biophysical Journal, 1995 The effects of five diacylglycerols (DAGs), diolein, 1-stearoyl,2-arachidonoyl-sn-glycerol, dioctanoylglycerol, 1-oleoyl,2-sn-acetylglycerol, and dipalmitin (DP), on the structure of lipid bilayers composed of mixtures of phosphatidylcholine and phosphatidylserine (4:1 mol/mol) were examined by 2H nuclear magnetic resonance (NMR ...

Design and applications of a fluorescent labeling technique for lipid and surfactant preformed vesicles [PDF]
ACS Omega 4, 10485-10493 (2019), 2019 Amphiphilic molecules such as surfactants, lipids and block copolymers can be assembled into bilayers and form vesicles. Fluorescent membrane labeling methods require the use of dye molecules that can be inserted in the bilayers at different stages of the synthesis. To our knowledge there is no generalized method for labeling preformed vesicles. Herein

Food Science and Human WellnessAcrylamide is classified as a Class 2A carcinogen and mainly metabolized to produce hepatotoxicity. Phosphatidylcholine is thought to protect the liver from damage, but the protective role of phosphatidylcholine on acrylamide-exposed metabolic disorders ...

Sterols sense swelling in lipid bilayers [PDF]
, 1998 In the mimetic membrane system of phosphatidylcholine bilayers, thickening (pre-critical behavior, anomalous swelling) of the bilayers is observed, in the vicinity of the main transition, which is non-linear with temperature. The sterols cholesterol and androsten are used as sensors in a time-resolved simultaneous small- and wide angle x-ray ...

Phenomenological Model and Phase Behavior of Saturated and Unsaturated Lipids and Cholesterol [PDF]
, 2008 We present a phenomenological theory for the phase behavior of ternary mixtures of cholesterol and saturated and unsaturated lipids, one which describes both liquid and gel phases, and illuminates the mechanism of the behavior.

Anti-inflammatory Effects of Phosphatidylcholine [PDF]
Journal of Biological Chemistry, 2007 We recently showed that mucus from patients with ulcerative colitis, a chronic inflammatory disorder of the colon, is characterized by a low level of phosphatidylcholine (PC) while clinical studies reveal that therapeutic addition of PC using slow release preparations is beneficial. The positive role of PC in this disease is still elusive.
