Phenylalanine is an essential amino acid, meaning that it cannot be produced by the body and must be obtained through dietary sources. It is found in many foods, including meats, dairy products, eggs, nuts, and seeds. It is also available as a dietary supplement. Phenylalanine is the precursor for the neurotransmitters dopamine, epinephrine, and norepinephrine, which are important for mood regulation.
Phenylalanine is sometimes referred to as a conditionally essential amino acid, as it can be synthesized in the body with the aid of certain enzymes. In cases where these enzymes are not available, it is essential that phenylalanine be obtained through dietary sources. It is also referred to as an aromatic amino acid due to its distinct odor.
Phenylalanine has several roles in the body. It is involved in the production of several hormones, including melatonin, thyroxine, and thyroid stimulating hormone. It is also essential for the synthesis of proteins and enzymes, and is necessary for proper growth and development. Additionally, phenylalanine plays an important role in the regulation of blood sugar levels.
