Properties

Dextran, also known as dextran, is a homopolysaccharide composed of glucose as monosaccharide. The different length of glucan chain determines its different medicinal value. Long chain glucan is usually a blood volume expansion drug with a molecular weight of tens of thousands to hundreds of thousands; Short chain dextran can be complexed with iron hydroxide to make dextran iron, namely iron dextran.
