Guluronic acid is a uronic acid that is a key component of alginates, which are polysaccharides derived from brown seaweed. It is characterized by its structure, which includes a carboxylic acid group and a hydroxyl group, contributing to its solubility in water and its ability to form gels. Guluronic acid is known for its role in the formation of the alginate polymer, where it alternates with mannuronic acid units, influencing the physical properties of the alginate, such as viscosity and gel strength. This compound exhibits biocompatibility and biodegradability, making it suitable for various applications in the food industry, pharmaceuticals, and biotechnology. Additionally, guluronic acid has potential health benefits, including its use as a dietary fiber and its role in drug delivery systems. Its CAS number, 15769-56-9, is used for identification in chemical databases and regulatory frameworks. Overall, guluronic acid is a versatile substance with significant industrial and biomedical relevance.

Glucuronic acid is a sugar acid derived from glucose, with its sixth carbon atom oxidized to a carboxylic acid. In living beings, this primary oxidation occurs with UDP-α-D-glucose (UDPG), not with the free sugar.
Glucuronic acid, like its precursor glucose, can exist as a linear (carboxo-)aldohexose (<1%), or as a cyclic hemiacetal (furanose or pyranose). Aldohexoses such as D-glucose are capable of forming two furanose forms (α and β) and two pyranose forms (α and β). By the Fischer convention, glucuronic acid has two stereoisomers (enantiomers), D- and L-glucuronic acid, depending on its configuration at C-5. Most physiological sugars are of the D-configuration. Due to ring closure, cyclic sugars have another asymmetric carbon atom (C-1), resulting in two more stereoisomers, named anomers. Depending on the configuration at C-1, there are two anomers of glucuronic acid, α- and β-form. In β-D-glucuronic acid the C-1 hydroxy group is on the same side of the pyranose ring as the carboxyl group. In the free sugar acid, the β-form is prevalent (~64%), whereas in the organism, the α-form UDP-α-D-glucuronic acid (UDPGA) predominates.
