Fig. 8
Density profile of glycine as a function of the distance from the nucleus of 67P when it presents a distributed source for which glycine molecules are embedded in water ice on particles with 1.7 × 10−5% glycine and with 1.7 × 10−5% parent glycine from the nucleus. The blue line corresponds to 30% porosity, and the red line represents particles with 90% porosity.
