Abstract
The work considers the transverse bending of the surface of a bilayer lipid membrane and the lateral pressure profile in the neutral part of the membrane within the framework of the model of lipid molecules as flexible elastic chains. When the shape of the membrane changes, the lateral pressure profile may also change. Using the renorm group, the addition to the lateral pressure profile during transverse bending of the membrane was calculated. The tilt moduli for several lipid species were calculated. Torsional modulus and Gaussian modulus calculations were performed for model membranes consisting of polymer rods. The results of the calculations are compared with available experimental and molecular dynamics data.
期刊介绍：
Biochemistry (Moscow), Supplement Series A: Membrane and Cell Biology is an international peer reviewed journal that publishes original articles on physical, chemical, and molecular mechanisms that underlie basic properties of biological membranes and mediate membrane-related cellular functions. The primary topics of the journal are membrane structure, mechanisms of membrane transport, bioenergetics and photobiology, intracellular signaling as well as membrane aspects of cell biology, immunology, and medicine. The journal is multidisciplinary and gives preference to those articles that employ a variety of experimental approaches, basically in biophysics but also in biochemistry, cytology, and molecular biology. The journal publishes articles that strive for unveiling membrane and cellular functions through innovative theoretical models and computer simulations.
