Prolactin and mammotrophic are secreted by the anterior pituitary gland. The only hormones secreted by the posterior pituitary are ADH/vasopressin and oxytocin. Post your comments Post Anonymously Please enter the code:
Several important peptide hormones are secreted from the pituitary gland. The anterior pituitary secretes three hormones: prolactin , which acts on the mammary gland ; adrenocorticotropic hormone (ACTH), which acts on the adrenal cortex to regulate the secretion of glucocorticoids ; and growth hormone , which acts on bone , muscle , and the liver . The posterior pituitary gland secretes antidiuretic hormone , also called vasopressin, and oxytocin . Peptide hormones are produced by many different organs and tissues, however, including the heart ( atrial-natriuretic peptide (ANP) or atrial natriuretic factor (ANF)) and pancreas ( glucagon , insulin and somatostatin ), the gastrointestinal tract ( cholecystokinin , gastrin ), and adipose tissue stores ( leptin ).  
We constantly seek ways to improve our quality systems and welcome any suggestions from our customers. Our commitment to quality is ongoing throughout the manufacturing process. The process begins with raw material quality inspection (RMQ), in-process quality inspection (IPQ) and on to final product quality inspection (FPQ) which are subject to a battery of analytical tests. Each peptide is accompanied with a certificate of analysis which includes details of the peptide, quantity and purity supplied, and helpful information on the solubility of the peptide in the buffers used during purification. Purified peptides also include a printout of the analytical HPLC profile and electrospray MS data. Peptides are also shipped with "A guide to handling peptides" and "Interpreting the results of peptide analysis".
