Description

Amylopectin: A highly branched glucan in starch. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

amylopectin : A polydisperse highly branched polysaccharide derivative composed of chains of D-glucopyranose residues in alpha(1->4) glycosidic linkage. The chains are joined together by alpha(1->6) glycosidic linkages. A small number of alpha(1->3) glycosidic linkages and some 6-phosphate ester groups also may occur. The branches in amylopectin typically contain 24 to 30 glucose residues.

Research Excerpts

Overview

Amylopectin is a highly branched glucan which accounts for approximately 65-85% of starch in most plant tissues. It is a naturally hyperbranched biopolymer with an extremely high molecular weight.
