Guluronic acid

Uronic acid monosaccharide derived from gulose

Guluronic acid is a uronic acid monosaccharide that may be derived from gulose.[1] l-Guluronic acid is a C-3 epimer of l-galacturonic acid and a C-5 epimer of d-mannuronic acid.[2] Along with d-mannuronic acid, l-guluronic acid is a component of alginic acid, a polysaccharide found in brown algae.[3] α-L-Guluronic acid has been found to bind divalent metal ions (such as calcium and strontium) through the carboxylate moiety and through the axial-equatorial-axial arrangement of hydroxyl groups found around the ring.[4]
