Metabolite Identification
Common NameNeurotensin 11-13
DescriptionNeurotensin is a 13 amino acid neuropeptide that is implicated in the regulation of luteinizing hormone and prolactin release and has significant interaction with the dopaminergic system. Neurotensin was first isolated from extracts of bovine hypothalamus based on its ability to cause a visible vasodilation in the exposed cutaneous regions of anesthetized rats. This structure shows the 11-13 fragment of neurotensin.
