WebMaltose (/ ˈ m ɔː l t oʊ s / or / ˈ m ɔː l t oʊ z /), also known as maltobiose or malt sugar, is a disaccharide formed from two units of glucose joined with an α(1→4) bond.In the isomer isomaltose, the two glucose molecules are joined with an α(1→6) bond.Maltose is the two-unit member of the amylose homologous series, the key structural motif of starch. WebStarch is a polysaccharide composed of two types of polymers – amylose and amylopectin. Amylose constitutes 20-25% of the starch molecule. It is a linear chain consisting of repetitive glucose units linked by α-1, 4-glycosidic linkage. Amylopectin constitutes 75-80% of starch and is characterized by branched chains of glucose units.
