Amine hormones are derived from the amino acids tyrosine and tryptophan. Here are some examples:
Amine Hormones Examples
| Hormone | Derived From | Function |
|---|---|---|
| Melatonin | Tryptophan | Regulates circadian rhythm |
| Epinephrine | Tyrosine | Fight-or-flight response |
| Norepinephrine | Tyrosine | Similar to epinephrine, affects alertness |
| Dopamine | Tyrosine | Involved in reward, motivation, and movement |
| Thyroid hormones | Tyrosine | Regulate metabolism |
Key Points
- Tryptophan Derivative: Melatonin, produced by the pineal gland, helps manage our sleep-wake cycle, known as the circadian rhythm.
- Tyrosine Derivatives:
- Thyroid hormones, important for regulating metabolism.
- Catecholamines, including epinephrine (adrenaline), norepinephrine (noradrenaline), and dopamine. These hormones play various roles, including the body's response to stress, alertness, and neurotransmission.
Summary
Amine hormones play diverse and vital roles in the body. Melatonin influences sleep, while catecholamines like epinephrine, norepinephrine, and dopamine influence our response to stress, alertness, and mood. Additionally, thyroid hormones, derived from tyrosine, are essential for maintaining metabolic balance.
