Reaction products formed after strong acid treatment of alpha-amino-delta-hydroxyvaleric acid.


High-voltage paper electrophoresis and analytical and preparative amino acid ion-exchange chromatography were used to investigate the products resulting from strong acid treatment and strong acid treatment and subsequent alkalinization of alpha-amino-delta-hydroxyvaleric acid. After strong acid treatment, alpha-amino-delta-hydroxyvaleric acid and proline… (More)
