guluronic acid Guluronic acid is a uronic acid monosaccharide that may be derived from gulose. -Guluronic acid is a C-3 epimer of -galacturonic acid and a C-5 epimer of -mannuronic acid. Along with -mannuronic acid, -guluronic acid is a component of alginic aci ...
, -mannuronic acid is a component of
alginic acid Alginic acid, also called algin, is a naturally occurring, edible polysaccharide found in brown algae. It is hydrophilic and forms a viscous gum when hydrated. When the alginic acid binds with sodium and calcium ions, the resulting salts are kn ...
