BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Prolactin is a polypeptide hormone that is responsible for lactation, breast development, and hundreds of other actions needed to maintain homeostasis. The chemical structures prolactin is similar to the structure of growth hormone and placental lactogen hormone.

Detailed explanation-2: -Prolactin is a polypeptide hormone that is synthesized in and secreted from specialized cells of the anterior pituitary gland, the lactotrophs.

Detailed explanation-3: -Prolactin. Prolactin is necessary for the secretion of milk by the cells of the alveoli. The level of prolactin in the blood increases markedly during pregnancy, and stimulates the growth and development of the mammary tissue, in preparation for the production of milk (19).

Detailed explanation-4: -Gonadotropin-Releasing Hormone Stimulates Prolactin Release from Lactotrophs in Photoperiodic Species Through a Gonadotropin-Independent Mechanism.

Detailed explanation-5: -Prolactin promotes the growth of a certain type of breast tissue called mammary alveoli, which are the components of the mammary gland where the production of milk occurs. Prolactin also stimulates the breast alveolar cells to create milk components, including: Lactose (the carbohydrate component of milk).
