Glucosylceramide (Glc beta 1-1Cer) and a novel ceramide trihexoside (Gal beta 1-6Gal beta 1-6Glc beta 1-1Cer) were purified from the eggs of the sea urchin, Hemicentrotus pulcherrimus. Their chemical structures were determined by gas-liquid chromatography, methylation analysis, chromic acid oxidation, enzymatic hydrolysis, enzyme-linked immunosorbent assay, fast atom bombardment mass spectrometry, and proton nuclear magnetic resonance spectroscopy. The ceramide trihexoside has a novel… 
Unique Catabolic Pathway of Glycosphingolipids in a Hydrozoan, Hydra magnipapillata, Involving Endoglycoceramidase*
The results indicate that the EGCase is indispensable for the catabolic processing of dietary glycosphingolipids in hydra, demonstrating the unique catabolic pathway for glycosphersolipid processing in the animal.

Synthesis of sphingosines, 11. Convenient synthesis of phytosphingosine and sphinganine from D‐galactal and D‐arabitol
3,4,6-Tri-O-benzyl-D-galactal (3) was directly converted into 3,4,6-tri-O-benzyl-2-deoxy-D-galactose (5). Wittig reaction of 5 with alkyltriphenylphosphonium salts in the presence of n-butyllithium
Synthesis of sphingosines, 9. Synthesis of phytosphingosine derivatives
Reaction of the lithium acetylide prepared from bromooctene 2 with 2,4-O-benzylidene-D-threose (1) yielded the epimeric dodec-5-ynetetrol derivatives 3a, b. Reaction of the Grignard reagent of
Methyl beta-allolactoside [methyl beta-D-galactopyranosyl-(1-->6)-beta-D-glucopyranoside] monohydrate.
Structural comparisons of methyl beta-allolactoside with related disaccharides bound to a mutant beta-galactosidase reveal significant differences in hydroxymethyl conformation and in the degree of ring distortion of the betaGlcp residue.
