We have identified propiololdehyde as a product of the action of an electric discharge on mixtures of methane and water or methane, nitrogen, and water. The aldehyde reacts with cyanoacetaldehyde and ammonia (other "prebiological molecules") to yield nicotinonitrile. This substance can be hydrolyzed to nicotinamide and nicotinic acid.
我们已鉴定出丙炔醛是放电作用于甲烷与水的混合物或甲烷、氮气和水的混合物时产生的一种产物。该醛与氰基乙醛和氨(其他“前生物分子”)反应生成烟腈。这种物质可水解为烟酰胺和烟酸。
