ACTH (3-24) is a peptide chain composed of amino acids 3-24 in the ACTH sequence, which almost contains the central region fragment of ACTH's biological activity. The study of this fragment is conducive to a better understanding of the biology of ACTH Activating blood. From the perspective of peptide synthesis and production, ACTH (3-24) sequence contains a relatively large number of basic amino acids, and the final product produced will contain a higher content of salt.
