title: Isolation of 1,3-distearoyl-glycero-2-phosphocholine (beta-lecithin) from commercial 1,2-distearoyl-sn-glycero-3-phosphocholine.
abstract: Different batches of 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC) had varying amounts of contaminants which appeared to affect systematic biological studies. This contaminant was separated by silica gel column chromatography followed by high performance liquid chromatography and identified as 1,3-distearoyl-glycerol-2-phosphocholine (beta-lecithin.
