Thymosin Alpha-1 mass & m/z.
Molecular formula C129H215N33O55 · 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 | 3108.32 g/mol |
|---|---|
| Monoisotopic mass | 3106.5041 Da |
Cross-check: matches the verified record (monoisotopic 3106.5041 Da, average 3108.31 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+ | 3107.5114 | 3109.32 |
| [M+2H]2+ | 1554.2593 | 1555.16 |
| [M+3H]3+ | 1036.5087 | 1037.11 |
| [M+4H]4+ | 777.6333 | 778.09 |
Isoelectric point (pI)
Not computed
pI is not published for this compound — modified N-terminus (Ac). A residue-pKa pI calculation is only valid for a linear, unmodified peptide of the standard 20 L-amino acids with free termini; computing one here would be a fabricated value.
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.
