The stereochemical configuration of lysosomal phosphatidylcholine and phosphatidylethanolamine: comparison with lysobisphosphatidic acid.

Lysosomal phosphatidylcholine and phosphatidylethanolamine were isolated from liver of rats treated with Triton WR 1339 and from cultured BHK-cells. Stereochemical analysis proved that these lipids, in contrast to the lysosomal lysobisphosphatidic acid, were derivatives of sn-glycero-3-phosphate.
