Livagen mass & m/z.
Molecular formula C18H31N5O9 · 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 | 461.47 g/mol |
|---|---|
| Monoisotopic mass | 461.2122 Da |
Average mass varies ~0.01–0.1 Da between atomic-weight tables; monoisotopic uses most-abundant-isotope masses.
ESI-MS m/z (positive mode)
| Charge state | m/z (monoisotopic) | m/z (average) |
|---|---|---|
| [M+1H]1+ | 462.2195 | 462.48 |
| [M+2H]2+ | 231.6134 | 231.74 |
| [M+3H]3+ | 154.7447 | 154.83 |
| [M+4H]4+ | 116.3103 | 116.37 |
Isoelectric point (pI)
4.18
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.
