ugh studies on the synthesis of amino acids, sugars and nucleic acids are very numerous, those on the prebiotic synthesis of fatty acids are very rare. The chemistry is not easy, but we do know that all prebiotic synthesis would have to be simple, fast and possible in vast quantities. In this paper,作者: 反話 時間: 2025-3-27 05:07
