In the field of neuroscience, substance P (SP) is a neuropeptide - a substance that functions as a neurotransmitter and as a neuromodulator. To be specific, substance P is an undecapeptide - a peptide composed of a chain of 11 amino acid residues. It belongs to the tachykinin neuropeptide family. Substance P and its closely related neuropeptide ne...
