But the terrestrial environment poses some of the same prob lems for building such molecules : although complex organic compounds could readily have been synthesized under primordial conditions , the energy that drives those chemical reactions is also enough to break the organic molecules apart 可是地球也有不利于氨基酸生存的惡劣條件:雖然地球在其形成初期也可能有條件合成復(fù)雜的有機(jī)物,但那些促使進(jìn)行這種化學(xué)反應(yīng)的能量也足以破壞氨基酸有機(jī)分子本身。
