As reported previously, glycine, serine, aspartic acid, and beta-alanine are the predominant amino acids produced from equimolecular formaldehyde and hydroxylamine in a modified sea medium enriched with essential transition metal ions. The time course of formation of the amino acids, and related substances was studied. Among the amino acids, glycine was produced earlier. Urea was produced initially and disappeared rapidly. Formation of cyanide, glycinenitrile, and glycinamide preceded the formation of amino acids. Probable pathways for the formation of amino acids and urea are suggested.
如先前报道，在富含必需过渡金属离子的改良海水培养基中，甘氨酸、丝氨酸、天冬氨酸和β-丙氨酸是由等分子甲醛和羟胺产生的主要氨基酸。研究了氨基酸及相关物质形成的时间进程。在这些氨基酸中，甘氨酸产生得较早。尿素最初产生并迅速消失。氰化物、甘氨腈和甘氨酰胺的形成先于氨基酸的形成。提出了氨基酸和尿素形成的可能途径。
