On the cluster structure of amylopectin
WebStarch, as a main energy storage substance, plays an important role in plant growth and human life. Despite the fact that several enzymes and regulators involved in starch biosynthesis have been identified, the regulating mechanism of starch synthesis is still unclear.

Web17 de nov. de 2024 · The fine structure of amylopectin greatly differs from that of glycogen in several ways. Amylopectin has a unit structure designated as cluster whereas glycogen has no such unit structure because upalpha -1,6 branch points are randomly distributed in glycogen ( Thompson, 2000 ).
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.”. how does the circle justice workWeb18 de jan. de 2010 · The sizes of the clusters in the form of beta-limit dextrins were uniform with an average degree of polymerization of 67-78.
