Mixed-linkage glucan
Mixed-linkage glucan (MLG) is a hemicellulosic polysaccharide, a homopolymer of glucose connected by β-D(1-3) and β-D(1-4) glycosidic bonds. It is a type of beta-glucan and is occasionally vaguely called beta-glucan in industrial contexts. MLG is highly prevalent within the Poales (which includes the cereals), where it has important properties in the diet.
In addition, although thought to be confined to the Poales, MLG has been found to be highly prevalent in plants of the distantly related genus Equisetum.
