✦ Synopsis

A purified sulfated alpha-L-galactofucan from Clavelina sp. has been studied before and after desulfation, using periodate oxidation, methylation analysis, and n.m.r. spectroscopy, and shown to be composed mainly of 3-sulfated 4-linked alpha-L-galactopyranosyl residues. There was also a small proportion of 3-sulfated 4-linked alpha-L-fucose residues.

The tunic of the ascidian Styela plicata is rich in a high molecular weight sulfated-L-galactan called the F-1 fraction. This polysaccharide is of complex structure and is highly branched. In this study we undertook detailed structural analysis of the F-1 fraction that was submitted to the Smith deg
