Substance P is a member of which neuropeptide family?

Substance P is a neuropeptide involved in transmitting pain signals and mediating inflammation. It belongs to the tachykinin family, which includes substance P along with related peptides like neurokinin A and neurokinin B, all typically acting on neurokinin receptors to regulate pain and vasodilation. The other listed families are distinct: opioids are peptide ligands that bind opioid receptors to dampen pain, somatostatins inhibit the release of other hormones, and endocannabinoids are lipid-based signaling molecules. So the best classification for substance P is that it is a member of the tachykinin family.
