Valine is a branched chain non-polar α-amino acid containing five carbon atoms, which has a wide range of applications in human nutrition additives, feed additives, flavorings, pharmaceuticals, pesticides and health products. Creative Proteomics can provide high performance liquid chromatography - mass spectrometry (HPLC-MS) to detect amino acids, which can target and quantitatively detect valine and related valine metabolites in the constituent proteins, ensuring that it can provide customers with scientific, accurate and comprehensive valine analysis report.
