DEFINITION

Classification: 536/51

(under subclass 18.7) Compounds which are high molecular weight polysaccharides containing D-glucose units linked predominately -D (16).

(1) Note. Dextrans yield only glucose on hydrolysis but differ otherwise from starch and glycogen as in molecular structure, etc.

(2) Note. Dextrans are usually a group of compounds differing according to the bacteria used to ferment the sugar.

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