The aldobiouronic acids of hemicellulose B of oat hulls

Partial hydrolysis of hemicellulose B from oat hulls yielded two aldobiouronic acids, which were identified as 2-O-(4-O-methyl-\u3b1-D-glucopyruronosyl)-D-xylose and 2-O-(\u3b1-D-glucopyruronosyl)-D-xylose respectively. In addition, two aldotriouronic acids were isolated, one yielding on hydrolysis xylose and 4-O-methyl-glucuronic acid, and the other, xylose, galactose, and glucurone.Peer reviewed: YesNRC publication: Ye
