The weakest link: Radiation induces the fragmentation of amino acids and is mainly driven by the cleavage of the CCα bond; the weakest bond of the system. By embedding the amino acid in clusters, the fragmentation pattern changes drastically. The weak hydrogen-bonded network (see picture) preferentially breaks, leading to a protective effect of the environment acting as “buffer”.
