Definition

Acetamide is an organic molecule with potential astrobiological significance, since it includes an amide bond, –NHCO–, which makes it potentially a marker of hydrolytic activity. Acetamide has been detected in the interstellar medium in the Galactic Center molecular cloud SgrB2, in carbonaceous chondrites (e.g., Halfen et al. 2011), and also apparently in the nucleus of comet 67P/Churyumov–Gerasimenko by the Philae lander as part of the Rosetta mission of the European Space Agency (Goesmann et al. 2015).
