GtoPdb Ligand ID: 1152

Immunopharmacology Ligand
Comment: Sequences of human, mouse and rat VIP are identical

VIP was first isolated and sequenced from pig small intestine [12,15].

As with many peptide molecules, there is ambiguity surrounding representations of the exact stereochemistry of VIP. The structure shown here does not specify stereochemistry.
