title: Zwitterionic digalactosylceramides from the earthworm, Pheretima asiatica.
abstract: Nine homogeneous glycosphingolipids were isolated from the earthworm, Pheretima asiatica (Annelida). All of them are digalactosylceramides carrying a choline phosphate group in the outer galactose moiety. Their full structures including the position of a phosphocholine unit were determined based on chemical and spectral evidence.
