Diphytanoyl phosphatidylcholine

WebDPPC (1,2-Dipalmitoyl-sn-glycero-3-phosphocholine) is a kind of glycerol phosphate, which has been used to prepare liposome monolayer/bilayer. It is used as a lung surfactant and diagnostic aid (fetal lung maturity). Synonyms: 1,2-Dipalmitoyl-sn-glycero-3- Phosphatidylcholine; L-Dipalmitoyl Lecithin. WebA pH gradient that develops within the USL must be taken into account under these conditions. From the concentration distribution of ammonium ions recorded at both sides of the BLM, the membrane permeability for ammonia is determined for BLMs of different lipid composition (48 x 10(-3) cm/s in the case of diphytanoyl phosphatidylcholine).
