A linear tripeptide, H-Lys-Glu-Asp-OH (single-letter KED), of L-lysine, L-glutamic acid and L-aspartic acid with free termini. Formula C15H26N4O8. Identity is reconciled against PubChem CID 87571363: the stereo-defined InChIKey LLSUNJYOSCOOEB-GUBZILKMSA-N derived from the sequence matches the deposited record exactly (molecular formula and full InChIKey), with no unassigned stereocentres. The draft had left the InChIKey pending; live PUG-REST reconciliation at build confirms it. No CAS or UNII is asserted. A computed 3D conformer is held pending the chemist sign-off.

Reference context

Vesugen is a synthetic tripeptide, H-Lys-Glu-Asp-OH (single-letter KED), of L-lysine, L-glutamic acid and L-aspartic acid from the St. Petersburg (Khavinson) line of short peptide bioregulators — the same research family as Epithalon and Pinealon. 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 C15H26N4O8 and the values computed from it. No biological activity, mechanism, or use is described or implied.

How Vesugen is characterized

Identity rests on the molecular formula and mass. Electrospray mass spectrometry (ESI-MS) measures the mass-to-charge ratio of the intact molecule; the average and monoisotopic masses are computed from the verified formula and cross-check the composition. The residue sequence and the modifications noted above define the structure.

What is the amino-acid sequence of Vesugen?
Vesugen has the sequence Lys-Glu-Asp. A linear tripeptide, H-Lys-Glu-Asp-OH (single-letter KED), of L-lysine, L-glutamic acid and L-aspartic acid with free termini. Formula C15H26N4O8. Identity is reconciled against PubChem CID 87571363: the stereo-defined InChIKey LLSUNJYOSCOOEB-GUBZILKMSA-N derived from the sequence matches the deposited record exactly (molecular formula and full InChIKey), with no unassigned stereocentres. The draft had left the InChIKey pending; live PUG-REST reconciliation at build confirms it. No CAS or UNII is asserted. A computed 3D conformer is held pending the chemist sign-off.
What is the molecular formula of Vesugen?
Vesugen has the molecular formula C15H26N4O8, giving an average molecular weight of 390.39 g/mol and a computed monoisotopic mass of 390.1751 Da.
What are the key chemical identifiers for Vesugen?
The CAS Registry Number for Vesugen is —. Its PubChem CID is 87571363 and its InChIKey is LLSUNJYOSCOOEB-GUBZILKMSA-N.
Is Vesugen a peptide?
Yes. Vesugen is a peptide — a chain of amino-acid residues joined by peptide bonds, 3 residues in length. Its identity is defined by that sequence and its molecular mass.
How is Vesugen stored and reconstituted?
As a research material, Vesugen 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.
Does Lineará sell Vesugen?
No. Vesugen 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.
Is Vesugen approved for human use?
No. Vesugen 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.
