Related Catalog	Research Areas >> Others Natural Products >> Saccharides and Glycosides
Target	Human Endogenous Metabolite
In Vitro	Maltose is the two-unit member of the amylose homologous series, the key structural motif of starch. When beta-amylase breaks down starch, it removes two glucose units at a time, producing maltose. In the isomer isomaltose, the two glucose molecules are joined with an α(1→6) bond.
