Thermodynamics and Transport Properties (01a)

#125 - Thermodynamics and Transport in Lipid Bilayers (01A14)
Lipid bilayers constitute the main structural component of biological membranes. In recent years, advances in experimental techniques and simulation methods have contributed to the widespread study of these complex self-assembled structures. The properties of these bilayers play a vital role in physiological functions, for example, the interaction between these membranes and sugars or proteins is considered to be crucial for understanding the mechanisms underlying phenomena such as cryoprotection and progression of diseases like the Alzheimer's disease. This session will focus on current efforts, both experimental and computational, for studying the thermodynamics of lipid bilayers and its role in governing the biochemical and biophysical functions of these membrane structures.
