AS THE ELECTRON DENSITY WAS NOT CLEAR ENOUGH TO SUPPORT THE ENTIRE PHOSPHOLIPID IN EACH CASE, THE ACTUAL IDENTITY OF EACH UNL HETERO GROUP IS UNKNOWN. ELECTRON DENSITY WAS NOT CLEAR ENOUGH TO DETERMINE WHETHER THE FATTY ACID CHAIN IS UNSATURATED. THEREFORE, ALL C-C BONDS FOR PCW HETERO GROUP WERE REFINED AS SINGLE BONDS.
