The beta glucan test kit is suitable for the measurement and analysis of beta glucan mixed linkage for the measurement of 1314 d glucan in cereal grains milling fractions wort beer and other food products see our complete range of polysaccharide assay kits. The glucan component is predominantly composed of glucose polymers linked in a linear arrangement by carbons 1 and 3 through a glycosidic bond with a beta configuration to form the 1 3 d glucan backbone 7 the biosynthesis of this polysaccharide backbone involves the transportation of glucose subunits to the plasma membrane where they are then transported across the plasma membrane and . The beta glucan fraction of low molar mass revealed high beta glucan content with a neglible amount of soluble proteins and amine nitrogen in addition antioxidant activity was very low and within the range of interference caused by residual proteins which means that no residual polyphenolic compounds were present in the fraction the high molar mass beta glucan fraction was characterized by . The structure of seaweed glucans showed by nmr spectroscopy is composed of two parts 13 glucan as backbone and about another one fifth of 16 glucan as sidechains alginates are typically bonded with hundreds of d mannuronic acid and l guluronic acid residues carrageenan and agar are sulphated galactans with basic linear structure of galactose residues but they differ from each
