✦ Synopsis

The cell wall microfibrils of Bryopsis maxima, a member of the order Siphonales which have been referred to as "noncellulosic plants", contain c 10% of n-glucan and ~90% of ( 1-3)~/I-D-xylan. A combination of enzymic analysis and 'H-n.m.r. spectroscopy confirmed that the D-ghCan was cellulose and that the algal cell-wall microfibtil seems to be composed not of a D-gluco-D-xylan but, mainly of a (1+3)-)5-u-xylan with small proportions of cellulose, which seemed to be present in an amorphous state in contrast to the trihelical strands of the (I -13)~B-o-xylan. * Studies on cell wall polysaccharides from siphonous green algae, Part III. For Part II, see ref. 1.
