Self-assembling amphiphilic molecules: Synthesis in simulated interstellar/precometary ices
which the solar system formed. Near the end of the hot early phase of
star and planet formation, volatile, less refractory materials were
transported into the inner solar system as comets and interplanetary
dust particles. Once the inner planets had sufficiently cooled, late
accretionary infall seeded them with complex organic compounds

contributed to the organic inventory necessary for the origin of life.
Interstellar ices, the building blocks of comets, tie up a large
fraction of the biogenic elements available in molecular clouds. In our
efforts to understand their synthesis, chemical composition, and
physical properties, we report here that a complex mixture of molecules
is produced by UV photolysis of realistic, interstellar ice analogs,
and that some of the components have properties relevant to the origin
of life, including the ability to self-assemble into vesicular
structures.
