VIP (Vasoactive Intestinal Peptide)

VIP (Vasoactive Intestinal Peptide) is a synthetic 28-residue neuropeptide, H-His-Ser-Asp-...-Ile-Leu-Asn (HSDAVFTDNYTRLRKQMAVKKYLNSILN), first isolated from hog small intestine in 1970; the free-acid form (PubChem CID 53314964) is the reference record here, with the endogenous C-terminally amidated form noted alongside. It is listed here strictly as an analytical reference entity — it is not sold, stocked, or certified by Lineará, and has no price or certificate of analysis. The data on this page is characterization only: molecular formula C147H237N43O43S and the values computed from it. No biological activity, mechanism, or use is described or implied.

VIP (Vasoactive Intestinal Peptide) has the sequence HSDAVFTDNYTRLRKQMAVKKYLNSILN. A 28-residue neuropeptide, H-His-Ser-Asp-Ala-Val-Phe-Thr-Asp-Asn-Tyr-Thr-Arg-Leu-Arg-Lys-Gln-Met-Ala-Val-Lys-Lys-Tyr-Leu-Asn-Ser-Ile-Leu-Asn (single-letter HSDAVFTDNYTRLRKQMAVKKYLNSILN), first isolated from hog small intestine by Said and Mutt in 1970; the human, mouse and rat sequences are identical. The identifiers here are for the FREE-ACID form deposited as PubChem CID 53314964 (formula C147H237N43O43S). Endogenous VIP is C-terminally amidated (Asn-NH2), which gives the distinct formula C147H238N44O42S — so the molecular formula and mass depend on which terminus is specified, a distinction recorded explicitly rather than elided. A single small-molecule InChIKey is omitted: VIP is represented by its verified sequence and PubChem CID, and the two termini would resolve to different keys.

VIP (Vasoactive Intestinal Peptide) has the molecular formula C147H237N43O43S, giving an average molecular weight of 3326.83 g/mol and a computed monoisotopic mass of 3324.7401 Da.

The CAS Registry Number for VIP (Vasoactive Intestinal Peptide) is 37221-79-7. Its PubChem CID is 53314964.

Yes. VIP (Vasoactive Intestinal Peptide) is a peptide — a chain of amino-acid residues joined by peptide bonds, 28 residues in length. Its identity is defined by that sequence and its molecular mass.

As a research material, VIP (Vasoactive Intestinal Peptide) is typically handled as a lyophilized (freeze-dried) powder. It is kept desiccated and cold — commonly 2–8 °C for short periods and −20 °C for longer storage — and reconstituted in sterile or bacteriostatic water. This is storage and handling information only, not a use protocol.

No. VIP (Vasoactive Intestinal Peptide) is listed here only as an analytical reference entity. It is not part of the Lineará formulary, has no price or certificate of analysis, and is not offered for sale.

No. VIP (Vasoactive Intestinal Peptide) is presented strictly as characterization reference data. It is not a drug, is not approved for any human or veterinary use, and must not be administered to humans or animals.
