BPC-157 mass & m/z.
Molecular formula C62H98N16O22 · Regenerative & Cytoprotective. Mass and m/z below are computed from the verified molecular formula; the isoelectric point is computed only where the sequence permits.
Molecular mass
| Average molecular weight | 1419.56 g/mol |
|---|---|
| Monoisotopic mass | 1418.7042 Da |
Cross-check: matches the verified record (monoisotopic 1418.7042 Da, average 1419.56 g/mol). Average mass varies ~0.01–0.1 Da between atomic-weight tables.
ESI-MS m/z (positive mode)
| Charge state | m/z (monoisotopic) | m/z (average) |
|---|---|---|
| [M+1H]1+ | 1419.7114 | 1420.56 |
| [M+2H]2+ | 710.3594 | 710.79 |
| [M+3H]3+ | 473.9087 | 474.19 |
| [M+4H]4+ | 355.6833 | 355.90 |
Isoelectric point (pI)
3.88
Method: Henderson–Hasselbalch net-charge bisection. pKa set: EMBOSS. Assumptions: Linear peptide, free N- and C-termini, standard 20 L-amino acids, no post-translational modifications. Published pKa sets differ, so treat pI as method-dependent (±~0.3).
Method & provenance
- Mass: element arithmetic over the verified molecular formula. Monoisotopic uses most-abundant-isotope masses (CODATA/AME); average uses IUPAC 2021 standard atomic weights.
- ESI-MS m/z: positive-mode protonated ions [M+nH]n+, m/z = (M + n·1.007276) / n, from the computed monoisotopic (and average) mass.
- pI: computed only for linear, unmodified peptides of the standard 20 L-amino acids with free termini; otherwise flagged. Values are analytical/characterization data only — no efficacy, dosing, or human-use meaning.
