Abstract:
1. A chemically crosslinked sugar derivative obtained via a reaction of a functional group of an isolated sugar derivative with a polyfunctional compound for crosslinking, the isolated sugar derivative isolated from a freshwater blue-green alga identified as Aphanothece sacrum, having a mean molecular weight of 2,000,000 or more and a repeat structure of a sugar chain unit containing a lactated, sulfated sugar as a sugar constituent, where a sugar constituent of a hexose structure and a sugar constituent of a pentose structure are conjugated together in a linear chain or a branched chain through an α-glycoside bond or a β-glycoside bond, where 2.7 or more hydroxyl groups per 100 hydroxyl groups are sulfated or sulfur element occupies 1.5% by weight or more of all of the elements in the sugar chain unit.
