On the cluster structure of amylopectin
WebThe most important functional difference between these forms is that ISA generally acts upon phytoglycogen and amylopectin by hydrolysing the α-1,6-linkages of polyglucans, which play impor- tant roles in the modification of excessively branched chains or the removal of improper branches of amylopectin formed by branching enzymes to … Web31 de ago. de 2024 · Amylopectin on the other hand is a branched polymer consisting of multiple, shorter chains of glucose connected by α-1, 4-glycosidic bonds. These short chains are then interconnected with α-1,...
