WebAmylopectin is generally the major component of starch and constitutes 65–85 % of the matter in the starch granules (Table 1.1) (Fredriksson et al. 1998; Gérard et al.~ 2001; Hoover 2001 ). However, in some mutant plants, the amylopectin content is much higher – it can even reach 100 % – and the sample is then known as “waxy starch.”. Web8 de set. de 2009 · Amaranthus amylopectin was hydrolyzed with alpha-amylase, and single clusters and a group of clusters (domain) were isolated by methanol precipitation. The domain and the clusters were treated with phosphorylase a and then beta-amylase to remove all external chains, whereby the internal structure was obtained.
