WebApr 10, 2024 · Starch consists of two ingredients-amylose and amylopectin. Amylose is a long linear chain of -D- (+)-glucose units joined by glycosidic association C1-C4 (along-link). Amylopectin is a branched-chain polymer consisting of ‐D-glucose units in which the chain is formed by glycosidic connection C1-C4 and glycosidic connection C1-C6 branches. WebIt is also called as amylopectin starch. Amylopectin makes around 70-80% of starch. It is a branched polymer of alpha D-glucose subunits that are linked via the same 1-4 glycosidic bonds as in amylose. However, amylopectin also has alpha 1-6 glycosidic bonds among the glucose molecules at the branch points.
