Five 1,2‐cyclic acetal‐type sn ‐glycero‐3‐phosphoethanolamines (CGPE) were isolated in a pure state from the sea anemone, Actiniogeton sp. (Coelenterata). Their structures, including the absolute configurations, have been determined on the basis of chemical and spectral data to be so‐called Feulgen's acetalphosphatides, which have been regarded as artifacts derived from original plasmalogens. We examined whether these CGPE are intact constitutents in the animal tissues and obtained reliable confirmation that CGPE are normally present in the sea anemone.
