Characteristic Metabolites for Inborn Errors of Amino Acid Metabolism

Inborn errors of metabolism are caused by changes in specific enzymatic reactions and hundreds of different such alterations, which affect about 1 of every 5000 newborns, have been characterized.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
