N-Methylacetamide (NMA), C3H7NO, is the smallest molecule to contain a
peptide bond and is considered to be the basic structural unit of pep
tide chains in proteins. An X-ray electron density study at 110 K show
ed the presence of static disorder. The present work describes this di
sorder and the configuration of this biologically important molecule.
