Webb7 nov. 2005 · It is generally accepted that soluble starch synthase (SS) and starch granule-bound starch synthase (GBSS) are involved in amylopectin and amylose synthesis, respectively, although the possibility that GBSS plays a role in forming long chains of amylopectin cannot be ruled out (Delrue et al., 1992). Webb28 dec. 2024 · 3. Starch Biosynthesis. Corn starch is composed of two polymers (homopolysaccharides), amylopectin and amylose, which differ in their chain length and degree of branching. Amylopectin is more highly branched (a chain of α-D-(1-4) and α-D-(1-6)-glucosidic linkages) and normally constitutes about 75% of the starch granule.
