An unusual glucocerebroside in the crustacean nervous system

K Shimomura, S Hanjura, PF Ki, and Y Kishimoto

High concentrations of glucocerebroside (glucosylceramide) were found in the ventral nerve cord, brain, optic nerve, and antenna, but not in the nonneural tissue, of the brown shrimp Penaeus aztecus aztecus. This lipid contained unusual sphingoid bases consisting of 14-, 15-, and 16-carbon sphinganines and sphingenines. The fatty acids were mainly nonhydroxylated homologs 22 carbons long and longer, similar to those found in galactocerebroside but differing from those in glucocerebroside in mammalian nervous systems.
