Peptide Hormones
Peptide hormones are molecules composed of small chains of amino acids, which act as chemical messengers within the body. They are synthesized in specific organs and tissues, and are secreted directly into the bloodstream. Peptide hormones are important for maintaining homeostasis and regulating complex bodily processes, such as metabolic rate, digestion, reproduction, growth and development. They also play an essential role in the immune system and are used to diagnose, treat and prevent a variety of diseases. For example, peptide hormones are used to regulate levels of insulin in people with diabetes, and to treat growth hormone deficiency in children and adults.
