Adrenocorticotropic Hormone (ACTH) (4-10), human, is primarily used in research and clinical studies to investigate its effects on the central nervous system. It is known to influence cognitive functions, including memory and learning, making it a valuable tool in neuroscience research. Additionally, it is studied for its potential role in modulating stress responses and its impact on behavior. This peptide fragment is also explored for its possible therapeutic applications in treating cognitive disorders and enhancing mental performance. Its ability to interact with melanocortin receptors further broadens its scope in studying skin pigmentation and related conditions.
