摘要: Polysaccharides with d-glucopyranose units joined in glucosidic linkages are the most abundant organic substances on earth. The major β-linked glucan polysaccharides β1,4-glucan (cellulose) and β1,3-glucans (e.g., curdlan, callose). Other β-glucans have a backbone of β-1,3-linked glucose associated variable low proportions internal β1,4- or β1,6-linkages pachyman, laminarin) regular pattern relatively high β1,4-linkages (mixed-linkage glucans).
