Summary:A process for preparing racemic alpha-amino acids or glycine, characterized in that the corresponding alpha-hydroxycarboxylic acid selected from hydroxyacetic acid, lactic acid, maleic acid, alpha-hydroxyglutamic acid, isocitric acid, tartronic acid and tartaric acid, or at least one salt of the corresponding alpha-hydroxycarboxylic acid is reacted with at least one nitrogen compound (c) in the presence of at least one heterogeneous catalyst containing at least one transition metal and in the presence of hydrogen, nitrogen compound (c) being selected from primary and secondary amines and ammonia.
