Work as a Messenger
Few proteins are hormones that are chemical messengers that help in communication within your organs, cells, and tissues. They form and the secretion is done through endocrine glands or tissues and then flows in your blood to the target organs or tissues where they attach to the receptors of protein on the cell surface. Hormones are categories into three chief groups including:
- Steroids: Fat cholesterol uses to form steroids. The estrogen, sex hormones, and testosterone are based on steroids.
- Peptides and proteins: These form from amino acid chains, varying from a few to various hundred.
- Amines: Amines form from the individual amino acid tyrosine or tryptophan, which aid in making the hormones linked to metabolism and sleep.
A few examples consist of:
-
- Glucagon: The breakdown of signals stores glucose in the liver.
- ADH (antidiuretic hormone): It gives messages to kidneys to absorb water again.
- Insulin: Insulin provides signals for the uptake of sugar or glucose into the cell.
- ACTCH (adrenocorticotrophic hormone): Regulates the secretion of cortisol, a major factor in metabolism.
