Abstract
A smaller molecule obtainable by allowing a sulfated fucan-digesting enzyme which digests a novel sulfated polysaccharide derived from an alga belonging to Laminariales to act on a sulfated fucan, and a method for producing the same.
Claims6
A sulfated fucan having the following chemical and physical properties:
- (1) containing fucose as a constituting saccharide;
- (2) containing a sulfated saccharide of general formula (I) as an essential component of the constituting saccharide:
- 17
- wherein R is H or SO3H, at least one of Rs is SO3H and n is an integer of 1 or more;
- and
- (3) being converted into smaller molecules by a sulfated fucan-digesting enzyme derived from Alteromonas sp. SN-1009 to generate at least one compound selected from the group consisting of the compounds of general formulas (II), (III), (XIII), (XIV), (XV) and (XVI):
- 18
- wherein R is H or SO3H and at least one of Rs is SO3H in all formulas above,
- or a salt thereof.
6 more elements
A sulfated fucan oligosaccharide of general formula (I):
- 19
- wherein R is H or SO3H, at least one of Rs is SO3H and n is 1 to 5.
A sulfated fucan oligosaccharide having a chemical structure selected from the group consisting of general formulas (II), (III), (XIII), (XIV), (XV) and (XVI):
- 20
- wherein
- R is H or SO3H and at least one of Rs is SO3H in all formulas above,
- or a salt thereof.
