What is dextran derived from?

Dextran is derived from the condensation of glucose, originally derived from wine.

How does IUPAC define dextrans?

IUPAC defines dextrans as branched poly-α-d-glucosides of microbial origin with glycosidic bonds predominantly C-1 → C-6.

What are the lengths of dextran chains?

Dextran chains can vary in length from 3 to 2000 kilodaltons.

What is the main chain of the dextran polymer composed of?

The main chain of the dextran polymer is composed of α-1,6 glycosidic linkages between glucose monomers.

How is dextran different from dextrin?

Dextran is characterized by its branching structure with α-1,3 linkages, while dextrin is a straight chain glucose polymer tethered by α-1,4 or α-1,6 linkages.
