在过渡金属离子溶液中由甲醛和羟胺形成氨基酸及相关低聚物。

J Mol Evol. 1977 Apr 29;9(2):105-9. doi: 10.1007/BF01732742.

In a solution of transition metal ions with or without kaolin not only amino acids but also their oligomers were formed. The maximum ratio of amino acids after to before acid hydrolysis 5 6.

在含有或不含有高岭土的过渡金属离子溶液中，不仅形成了氨基酸，还形成了它们的低聚物。酸水解后与酸水解前氨基酸的最大比例为5∶6。
