Proteins perform many physiological functions. For example, some proteins function as enzymes. Hormones represents an additional function that some proteins discharge (like insulin).

< b="" />Introduction< />
Proteins are macromolecules composed of amino acids and play a vital role in various physiological functions in living organisms. One of the well-known functions of proteins is their role as enzymes, which catalyze biochemical reactions. However, proteins also have additional functions, one of which is acting as hormones.

< b="" />Hormones< />
Hormones are chemical messengers produced by the endocrine system and are responsible for regulating various physiological processes in the body. They are secreted by specific glands and travel through the bloodstream to target cells or organs, where they bind to specific receptors and initiate a response. Protein hormones, also known as polypeptide hormones, are made up of amino acids and are derived from longer precursor proteins.

< b="" />Examples of Protein Hormones< />
Protein hormones are involved in a wide range of physiological processes, including growth, metabolism, reproduction, and homeostasis. Here are a few examples of protein hormones and their functions:

1. Insulin: Insulin is a protein hormone secreted by the pancreas. It plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose into cells.

2. Growth Hormone: Growth hormone, also known as somatotropin, is produced by the pituitary gland. It promotes growth and development in children and adolescents, as well as regulates metabolism in adults.

3. Thyroid-Stimulating Hormone (TSH): TSH is secreted by the pituitary gland and stimulates the thyroid gland to produce and release thyroid hormones, which regulate metabolism.

4. Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH): FSH and LH are gonadotropins produced by the pituitary gland. They play a crucial role in reproductive functions, such as the development of eggs in females and the production of testosterone in males.

< b="" />Conclusion< />
In addition to their role as enzymes, proteins also function as hormones in the body. Protein hormones play a crucial role in regulating various physiological processes and maintaining homeostasis. Understanding the diverse functions of proteins is essential for comprehending the complexity of biological systems and the intricate mechanisms that govern them.

Many hormones is made of by protein.
