Iduronate is a type of sugar molecule known as a uronic acid. It plays a crucial role in the structure of glycosaminoglycans, which are important components of connective tissues in the body. Iduronate is particularly significant in the synthesis of heparan sulfate and dermatan sulfate, both of which are involved in various biological processes. In humans, iduronate is produced from the metabolism of glucuronic acid. It is essential for maintaining the proper function of cells and tissues. Abnormalities in iduronate metabolism can lead to disorders such as Mucopolysaccharidosis type I (MPS I), which affects the body's ability to break down certain sugars.
