Production yields of organics of astrobiological interest from H2O-NH3 hydrolysis of Titan's tholins

► Titan's organic aerosols are deposited at the surface after their synthesis. ► Fate of Titan's aerosols at the surface is inferred by Earth-based experiments. ► Aerosol analogs placed in a cold NH3-H2O solution for 10 weeks incorporate oxygen ► We measure the production yields of several molecules of astrobiological interest. ► Quantification of urea, alanine, glycine and aspartic acid was performed.
