Peptide Hormones
Peptide hormones are small chains of amino acids that act as signaling molecules in the body. They are produced by various glands and organs, such as the pancreas and pituitary gland. These hormones travel through the bloodstream to communicate with specific cells, influencing functions like growth, metabolism, and mood. For example, insulin, a well-known peptide hormone, helps regulate blood sugar levels. Peptide hormones are essential for maintaining balance in bodily processes and responding to changes in the environment. Their precise roles are crucial for overall health and well-being.

Peptide hormones are small proteins made up of chains of amino acids that act as chemical messengers in the body. They are produced by various glands, such as the pancreas and pituitary, and are released into the bloodstream to regulate a wide range of physiological functions, including growth, metabolism, and mood. Unlike steroid hormones, which can pass through cell membranes, peptide hormones bind to specific receptors on the surface of cells, triggering a response inside the cell. This helps the body maintain balance and respond to changes in its environment effectively.
