Abstract
Oxytocin (9-amino acid peptide) hormone is a member of the G-protein coupled receptor family. It regulates a range of physiologic actions in mammals other than assisting parturition and lactation functions. Evidence indicates that oxytocin alters lipids, protein, and sugar metabolism through various ways including modulation of appetite and satiety, enzyme activity, cellular signals, secretion of metabolic hormones, and energy consumption. Alterations in these processes have the potential to shift developmental trajectories and influence disease processes. Oxytocin can be a potential avenue for the treatment of endocrine disorders such as obesity, diabetes mellitus, and associated disorders. The chapter will include a comprehensive study about oxytocin and its physiological and pathological functions, which makes it a potential target for drug therapy.
