Witryna5 sie 2024 · Starch is a homopolysaccharides made up of glucose units. However, the homopolysaccharide are of two types namely: amylose, which is a linear chain consisting of about 500–2000 glucose units, and amylopectin, which is highly branched and consist of over 1,000,000 glucose units. Witryna9 lut 2024 · Figure 1: SEM picture of regular rice starch. Rice amylopectin is a highly branched polymer with a DP of 8200-12800 (Figure 2). 3 Its uniqueness lies in its low amount of mid-sized end standing branches, also called C chains. A low presence of C chains is linked to a reduced tendency for retrogradation. 4.
