Abstract
Monolayers of a protein beta-lactoglobulin (BL) and two lipids distear oylphosphatidylcholine (DSPC) and dimirystoylphosphatidylcholine (DMPC ) on aqueous subphase containing Na+ or Ca2+ ions are studied. The spr eading isotherms and the ATR-FTIR spectra of LB plurilayers transferre d, allow to deduce that alpha-helix conformation of beta-lactoglobulin is the prevailing form. The study of bidimensional mixtures between b eta L with DSPC and with DMPC shows that the components are incompatib le at the W/A interface.
