Abstract It is established that glycine and glycine oligohomopeptides interact with formaldehyde and acetaldehyde in a homogeneous weak acid medium (pH 3.3–3.7) at mild temperatures (60–80°C) in the absence of inorganic solid substances. Together with the expected serine and threonine, the formation of alanine, glutamic and aspartic acid, norvaline and isoleucine, as well as four non-protein amino acids is also established. It is suggested that the non-protein amino acids are hydroxymethylserine, hydroxymethylthreonine, hydroxymethylaspartic acid and γ-amino-δ-hydroxyvaleric acid. The modes of formation of all protein and non-protein amino acids are discussed. These results strengthen the probability that similar processes may have been one of the pathways for the prebiotic synthesis of amino acids on primitive Earth.
