Guluronic acid explained

Guluronic acid is a uronic acid monosaccharide that may be derived from gulose.[1] -Guluronic acid is a C-3 epimer of -galacturonic acid and a C-5 epimer of -mannuronic acid.[2] Along with -mannuronic acid, -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]
