Thymosin alpha-1
Thymalfasin, also called thymosin alpha-1, is a linear 28-residue peptide. Its primary structural candidate corresponds to the N-terminal region of prothymosin alpha after the initiator methionine.
01
Identity & nomenclature
Thymalfasin, also called thymosin alpha-1, is a linear 28-residue peptide. Its primary structural candidate corresponds to the N-terminal region of prothymosin alpha after the initiator methionine.
Thymalfasin is the recommended international nonproprietary name; thymosin alpha-1 is the common scientific display name. The shared historical thymosin designation does not establish a common structural family with beta-thymosins.
Canonical name: Thymalfasin.
Declared aliases and development codes: Thymosin alpha1, Thymosin α1.
02
Molecular properties
Molecular formula, mass, sequence and registry identifiers are not listed for this record. The sources reviewed did not meet the two-source verification standard used in this library.
The primary structural candidate corresponds to residues 2-29 of reviewed human prothymosin alpha, using precursor numbering that includes the initiator methionine. Mature-peptide numbering starts at Ser1. The complete sequence is withheld because collected source renderings remain conflicted.
03
Structural characteristics
The defined candidate has an acetylated N-terminus and a free C-terminal carboxyl group. It is linear, with standard L-amino-acid residues and no cysteine or disulfide. The complete sequence, molecular formula and average molecular mass remain conflicted and are withheld.
Terminal features: N-terminal acetylation at Ser1, Free C-terminal carboxyl.

Analytical considerations
The acetyl cap is not an additional amino-acid residue. Average molecular mass, neutral monoisotopic mass and an ion mass are different quantities; agreement of a calculated candidate with one reported value does not resolve the held identity fields.

Methodology & citation verification
Reference identity is checked against official PubMed metadata. Local deterministic receipts bind each normalized title and canonical metadata record to its verification date. Scientific values remain absent when an authoritative source has not been verified.
