Activity

  • Function:  ACTH stimulates the adrenal glands to release cortisol.; MSH (melanocyte-stimulating hormone) increases the pigmentation of skin by increasing melanin production in melanocytes.; Beta-endorphin and Met-enkephalin are endogenous opiates.; [Corticotropin]: Stimulates the adrenal glands to release cortisol.; [Melanocyte-stimulating hormone alpha]: Anorexigenic peptide. Increases the pigmentation of skin by increasing melanin production in melanocytes.; [Melanocyte-stimulating hormone beta]: Increases the pigmentation of skin by increasing melanin production in melanocytes.; [Beta-endorphin]: Endogenous orexigenic opiate.; [Met-enkephalin]: Endogenous opiate.
