DEFINITION

Classification: 514/59

Dextran or derivative:

(under subclass 54) wherein the polysaccharide is composed of D-glucose units which are linked by 1, 6 glucosidic bonds.

(1) Note. Dextrin and dextrine are not variant spelling of "Dextran", instead they are respectively a starch hydrolysis product and a variant spelling of dextrin.

(2) Note. Controlled hydrolysis of native dextran yields clinical dextran of lower molecular weight which is useful as a blood plasma substitute.
