Evidence that (Glu4)-neurotensin is the naturally occurring neurotensin in plasma.

abstract：:A simple and computationally nonintensive technique based on principal component analysis of 3-dimensional fields to derive theoretical descriptors is presented. The descriptors are then applied to a quantitative structure-activity relationship study on bradykinin potentiating pentapeptides. ...
