The molecule is a peptide cation obtained from the deprotonation of the carboxy groups of L-alpha-glutamyl and L-leucine residues, and protonation of the side chains of L-lysyl and L-arginyl residues of neurotensin. It is the major species at pH 7.3. It has a role as a human metabolite. It is a conjugate acid of a neurotensin.
