A new QSAR model, for angiotensin I-converting enzyme inhibitory oligopeptides

► A new QSAR model was built for ACE inhibitory oligopeptides. ► A collection of 263 peptides and 38 physicochemical descriptors published was used. ► We used glm with a Gamma distribution for modelling the inhibitory activity. ► The model shows a predictive ability of 94.4%. ► Amino acids in C1 and C4 positions appear as the most relevant for ACE inhibition.
