alduronicacid
Alduronic acids are a class of sugar-derived acids formed when an aldose sugar is oxidized at the aldehyde end to produce a carboxyl group, resulting in aldo-uronic acids. They are a subset of uronic acids and are commonly encountered as components of complex polysaccharides in both animals and plants. In solution, these molecules can exist as ring forms (pyranoses or furanoses) and as their corresponding open-chain forms with a terminal carboxyl group.
Common examples include glucuronic acid, galacturonic acid, and iduronic acid. Glucuronic and galacturonic acids derive from
Biological roles and occurrence are diverse. In animals, glucuronic acid plays a central role in detoxification
Chemically, the carboxyl group of alduronic acids imparts acidity (typical pKa around 3–4) and enables various
