Abstract
A series of acidic oligosaccharides was obtained by graded, acid hydrolysis of the methylated, acidic polysaccharide associated with the coccoliths of the alga Emiliania huxleyi (Lohmann) Kamptner. After fractionation by ion-exchange chromatography, the structures of the oligosaccharides were determined by sugar analysis, g.l.c.-m.s. of the intact, permethylated oligosaccharide-alditols, and methylation
