properties of matter :The range of MW is 70,000 to 2-4 million Da Hyaluronic acid (HA) preparations have variable MW depending on purification procedures, the extent of degradation, as well as the source. Bovine vitreous humor HA has a lower MW than most other sources. The hyaluronic acid is a class of macromolecular proteoglycans characterized by a highly polymerized chain of glucuronic acid, N acetylglucosamine units bound to protein. A partialy purified powder. Suitable as a substrate for hyaluronidase assay.

molecular weight : 70,000~2-4 million Da
