At the air-water interface, a negatively charged amino acid carries out a nucleophile attack on a gas molecule to convert it into a product. The reaction rate is enhanced due to significant reduction ...

The reaction generates amino acids and nucleic acids, the building blocks of proteins and DNA. Four billion years ago, the Earth looked very different than it does today, devoid of life and covered by ...
