摘要：

(Figure Presented) Sum mothers do 'ave 'em: Sum-frequency generation spectroscopy was used to investigate the hydrolysis mechanism of a dipalmitoylphosphatidylcholine bilayer by phospholipase A2 (PLA 2). This study describes the structural changes and the hydrolysis mechanism in each leaflet (red and black) of a supported lipid bilayer at a molecular level. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
