Definition

A gum obtained from the ground endosperms of Cyamopsis tetragonolobus (Linné) Taub. (Fam. Leguminosae). It consists mainly of a high molecular weight hydrocolloidal Polysaccharide, composed of galactose and mannose units combined through glycosidic linkages, which may be described chemically as a galactomannan.
