(1→4)-linked disaccharides. About 35–40% of (1→6)-and 15–20% of (1→4)-linked disaccharides were oxidatively degraded to smaller molecules after incubation for 24 h. Of the four disaccharides examined, namely, maltose, isomaltose, cellobiose, and gentiobiose, the α-(1→6)-linked disaccharide isomaltose exhibited the highest reactivity, whereas the β-(1→4)-linked disaccharidecellobiose showed the lowest
Mannoglucan derivatives wherein from about 2 to 51 per 100 of side chain .alpha.-D-mannopyranosyl residues of mannoglucan have been cleaved and reduced to polyhydroxy residues possess antitumor activity with reduced pyrogenecity.
