A linear dipeptide, H-Lys-Glu-OH (single-letter KE), of L-lysine and L-glutamic acid joined by a single peptide bond, with free alpha-amino and alpha-carboxyl termini — non-amidated and non-cyclic. Its formula C11H21N3O5 follows from the two residues less one water. The alpha-linked L,L constitution is confirmed against PubChem: the stereo-defined InChIKey UGTZHPSKYRIGRJ-YUMQZZPRSA-N derived from the sequence resolves to the stereo-defined records (PubChem CID 7010501/7010502), and its connectivity block matches CID 14304541 — the CAS-linked N-L-lysyl-L-glutamic-acid record, which is deposited without stereochemistry. That connectivity match rules out the isopeptide isomers (gamma-glutamyl-lysine) that share the C11H21N3O5 formula and could not be distinguished by mass alone. A computed 3D conformer is held pending the launch-wide chemist sign-off.
Reference context
Vilon is a synthetic dipeptide, H-Lys-Glu-OH (single-letter KE), of L-lysine and L-glutamic 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 C11H21N3O5 and the values computed from it. No biological activity, mechanism, or use is described or implied.
Listed solely as a characterized analytical reference — no representation is made as to any biological effect. For Research Use Only — not for human or veterinary use.
How Vilon 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.
