A linear tetrapeptide, H-Lys-Glu-Asp-Pro-OH (single-letter KEDP), of L-lysine, L-glutamic acid, L-aspartic acid and L-proline with free termini. Formula C20H33N5O9 from the four residues less three waters, reconciled with the sequence-derived structure (no unassigned stereocentres). It is a single, chemically defined peptide and should not be confused with prostate-derived polypeptide complexes (prostatilen / Vitaprost-type extracts), which are undefined mixtures. Registry coverage is thin: no PubChem CID, CAS, UNII, or InChIKey is asserted here, and the entity ships as ChemicalSubstance on its verified sequence and formula (see the identifiers report). A computed 3D conformer is held pending the chemist sign-off.
Reference context
Prostamax is a synthetic tetrapeptide, H-Lys-Glu-Asp-Pro-OH (single-letter KEDP), of L-lysine, L-glutamic acid, L-aspartic acid and L-proline from the St. Petersburg (Khavinson) line of short peptide bioregulators — a single defined molecule, distinct from prostate-derived polypeptide extract complexes. 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 C20H33N5O9 and the values computed from it. No biological activity, mechanism, or use is described or implied.

How Prostamax 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.
