FIG. 1. Block sites of alginate polymer and alginate lyase
reactions. A, MM; B, GG; C, MG block sites. M and G represent
-D-mannuronate and -L-guluronate. Vertical
arrows indicate cleavage sites for alginate lyase reactions and
horizontal arrows indicate those for reactions. D, reaction
scheme for the TBA method.
