Hormones

Hormones are chemical agents which act on distant organs.

They can be either protein or peptide (e.g. insulin), amine or steroid (e.g. testosterone).

 

Polypeptide or protein hormones

  • Corticotropin-release factor (CRF)

  • Growth hormone release hormone (GHRH)

  • Luteinizing hormone release hormone (LHRH)

  • Somatostatin

  • Thyrotropin-release hormone

Peptides of neurohypophysis

  • Vasopressin (arginine vasopressin)

  • Oxytocin

Peptides of adenohypophysis

Pro-opiomelanocortin (POMC) derivatives

  • Corticotropin (ACTH)

  • Corticotropin-like intermediate lobe peptide (CLIP)

  • β-endorphins (B-END)

  • β-lipotropin (B-LPH)

  • γ-lipotropin (G-LPH)
