Common_NameErythronic acid
DescriptionErythronic acid is a sugar component of aqueous humour (eye). It may be derived from glycated proteins or from degradation of ascorbic acid. Erythronic acid is a normal organic acid present in a healthy adult and pediatric population. It has been found in urine, plasma, CSF and synovial fluid. (PMID: 14708889, 8087979, 8376520, 10420182) Erythronic acid is formed when N-Acetyl-D-glucosamine (GlcNAc) is oxidised. GlcNAc is a constituent of hyaluronic acid (HA), a polysaccharide consisting of alternating units of Glucuronic acid and GlcNAc, present as an aqueous solution in synovial fluid. In synovial fluid of patients suffering from rheumatoid arthritis, HA is thought to be degraded either by radicals generated by Fenton chemistry (Fe2+/H2O2) or by NaOCl generated by myeloperoxidase.
