Differential effects of cholesterol, ergosterol and lanosterol on a dipalmitoyl phosphatidylcholine membrane: A molecular dynamics simulation study
Article Abstract:
Molecular dynamics simulation study is used to investigate the differential effects of three closely-related sterols, cholesterol, ergosterol and lanosterol on the dipalmitoyl phosphatidylcholine membrane. The findings prove that ergosterol is the most efficient of all three, as it helps in promoting the liquid-ordered phase, as well as the lipid domain formation in the membrane.

Decomposing complex cooperative ligand binding into simple components: connections between microscopic and macroscopic models
Article Abstract:
The framework of the decoupled sites representation (DSR), previously developed in the context of pH titration, is extended to include cooperative ligand binding as well as multiple conformations and multiple ligands. It cam be used to elucidate the connection between the experimentally observed binding curves and parameters of underlying microscopic models.Z

Relations between protonation constants and titration curves in polyprotic acids: A critical view
Article Abstract:
The titration curves of individual sites in polyprotic acids can be irregular and do not need to show a sigmoidal shape. For irregular titration curves, the pH at which protonation (pK(sub 1/2) value) takes place is 0.5, or the inflection of titration curves of individual sites or of the total titration curve cannot be identified with the pKa value.
