Molecular Weight Distribution of Whole Starch in Rice Endosperm by Gel-permeation Chromatography

Published in Journal of Applied Glycoscience

Starch is comprised of very large α-glucan molecules composed primarily of linear amylose and highly branched amylopectin. Most methods for analyses of starch structure use hydrolytic enzymes to cleave starch. When undegraded, whole starch structures can be analyzed by gel-permeation chromatography (GPC), but this typically yields a single peak eac...
