WebAug 7, 2024 · Amylose synthesis in itself is simple: the linear chains form through processive elongation by a single enzyme, the GRANULE BOUND STARCH SYNTHASE (GBSS). However, the process must occur in tight coordination with amylopectin synthesis to form granules of correct structure and composition. WebMay 1, 2024 · Starch is quantitatively the most dominant storage carbohydrate on Earth and is synthesized mostly in plants and some cyanobacteria [1]. Starch is accumulated as water-insoluble particles, i.e., the starch granules, whereas most other species produce water-soluble glycogen as a storage carbohydrate.
