Observation Of Complex Organic Molecules Containing Peptide-like Bonds Towards Hot Core G358.93−0.03 MM1
In the star formation regions, the complex organic molecules that contain peptide bonds (−NH−C(=O)−) play a major role in the metabolic process because −NH−C(=O)− is connected to amino acids (R-CHNH2−COOH).

Peptide Bonds In The Interstellar Medium: Facile Autocatalytic Formation From Nitriles On Water-Ice Grains
A recent suggestion that acetamide, CH3C(O)NH2, could be readily formed on water-ice grains by the acid induced addition of water across the CN bond is now shown to be valid. […]
