Biochem/physiol Actions

Erythronic acid is a sugar component of aqueous humour (eye). Erythronic acid is a normal organic acid present in a healthy adult and pediatric population and has been found in urine, plasma, CSF, aqueous humour (eye) and synovial fluid. Erythronic acid is formed when GlcNAc is oxidised.
