Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by α-(1→4)-D glycosidic bonds. This polysaccharide is produced by most green plants for energy storage. Worldwide, it is the most common carbohydrate in human diets, and is contained in large amounts in staple foods such as wheat, potatoes, maize (corn), rice, and cassava (manioc). Witryna27 mar 2024 · Amylose is minor, linear, or slightly branched component of starch. Potato amylose molecule consists of 200–20,000 glucose units with an average length of 270–525 glucosyl units, forming a helical structure through bond angles between glucose units (Pawar et al., 2008; Vamadevan & Bertoft, 2015).
