Abstract: Provided is a low-molecular-weight holothurian glycosarninoglycan, with the constituent units thereof being a glucuronic acid group, an N-acetaminogalactose group and a fucose group, and a sulfate ester group or acetyl ester group thereof. Glucuronic acid and N-acetaminogalactose are interconnected via ?(1-3) and ?(1-4) glucosidic bonds to form a backbone of a disaccharide repeating structural unit, and a fucose group is connected to the backbone as a side chain. On a molar ratio basis, the ratio of the glucuronic acid group:the N-acetaminogalactose group:the fucose group is 1:(0.8-1.2):(0.6-1.2). In the structure of the low-molecular-weight holothurian glycosaminoglycan, 10-30% of glucuronic acid groups are modified, on the 2-position, with a sulfate ester group, and the rest are hydroxyl groups; and a proportion of 10-30% of fucose groups is modified, on the 2-position, with an acetyl ester group, and the rest are hydroxyl or sulfate ester groups.
Abstract: Compositions, methods, systems, etc., are provided for modified and/or purified fucans and corresponding fucan-containing compositions that inhibit fibrous adhesions among other advantages. The purified/modified fucans and fucan compositions have a reduced level of non-fucan components or impurities such as those found in a starting fucan composition. Such reduced undesirable components or impurities include, for example, undesired components bound to the fucan and compounds in the composition that are not a part of or bound to the fucan.
