Abstract

WE have applied the method of paper partition chromatography to ascertain qualitatively the detailed amino-acid constitution of spongin, using the commercial unbleached honeycomb sponge, gathered in the eastern Mediterranean Sea. Our results differ in important respects from those of Low1, who used this method to investigate the amino-acid constitution of the barium hydroxide hydrolysate of the sponge, Spongia officinalis obliqua, collected in the Gulf of Mexico.
