Thymosin Alpha-1

Thymosin Alpha-1, also known in its synthetic form as thymalfasin, is a 28-amino-acid peptide first isolated and characterized from calf thymus tissue in 1977. It has the molecular formula C129H215N33O55, a molecular weight of 3,108.3 g/mol, and is identified by CAS number 62304-98-7. The peptide is notable for its N-terminal acetyl group and highly acidic amino-acid composition. Thymosin Alpha-1 is classified as an immunomodulatory peptide derived from prothymosin alpha and is studied for its involvement in T-cell function and immune signaling.
