Actions biochimiques/physiologiques

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.

Metabolomics is the rapidly evolving field of the comprehensive measurement of ideally all endogenous metabolites in a biological fluid. However, no single analytic technique covers the entire spectrum of the human metabolome. Here we present results from a multiplatform study
