Yes, prolactin is a polypeptide hormone.
Understanding Prolactin
Prolactin plays a crucial role in the human body. Here's a closer look:
- Definition: It's a hormone made of a chain of amino acids (a polypeptide).
- Primary Function: Well-known for its role in lactation (milk production) and breast development.
- Wider Effects: Prolactin has hundreds of other actions which contribute to maintaining homeostasis (the body's stable internal environment).
- Structural Similarities: Prolactin shares structural similarities with growth hormone and placental lactogen hormones.
Key Functions of Prolactin:
| Function | Description |
|---|---|
| Lactation | Stimulates milk production in mammary glands after childbirth. |
| Breast Development | Promotes growth and development of breast tissue, especially during pregnancy. |
| Homeostasis Maintenance | Involved in numerous processes that help maintain internal body balance. |
Prolactin & Other Hormones:
The fact that prolactin is structurally similar to growth hormone and placental lactogen highlights potential areas of shared functions and interactions between these hormones. Research into these overlaps continues to expand our understanding of hormonal regulation.
