Triptòfan

Triptòfan is an essential amino acid, meaning the human body cannot produce it and must obtain it through diet. It plays a crucial role in protein synthesis and is a precursor to several important biomolecules.

One of the most well-known functions of triptòfan is its role in the production of serotonin, a neurotransmitter that influences mood, sleep, appetite, and learning. Serotonin is synthesized from triptòfan through a series of enzymatic reactions. Additionally, serotonin can be further converted into melatonin, a hormone that regulates sleep-wake cycles.

Dietary sources of triptòfan include a variety of protein-rich foods such as poultry, eggs, dairy products, nuts, seeds, and legumes. While some foods are richer in triptòfan than others, a balanced diet generally provides sufficient amounts.

Triptòfan deficiency is rare in developed countries but can lead to symptoms associated with low serotonin levels, including depression, anxiety, and sleep disturbances. However, it's important to note that while triptòfan is a building block for serotonin, its direct supplementation does not always translate to increased serotonin levels in the brain due to various physiological factors. Research continues to explore the complex relationship between triptòfan intake and mental well-being.
