ABSTRACT
1. Ceramide aminoethylphosphonate was isolated from the adductor, gills, mantle and viscera of oysters. 2. After drastic acid hydrolysis of the lipid, aminoethylphosphonic acid was the only water-soluble carbon-phosphorous compound detected. 3. The main fatty acids of ceramide aminoethylphosphonates were hexadecanoic acid (77-90%) and 2-hydroxy hexadecanoic acid (13-15%). 4. Hexadeca-4-sphingenine, octadeca-4-sphingenine and octadeca-4,8-sphingadienine were identified as the major long chain base components. However, the ratio of the three bases was characteristic for each tissue; the adductor muscle contains primarily hexadeca-4-sphingenine, and the viscera, octadeca-4,8-sphingadienine. The gills and mantle contain the three bases in approximately equal concentration. 5. The main molecular species in the adductor muscle was hexadecanoyl-hexadeca-4-sphingenyl 2-aminoethylphosphonate, while in the viscera hexade-canoyl-octadeca-4,8-sphingenyl 2-aminoethylphosphonate predominated.
