Phenylalanine

L – Phenylalanine is used in all living organisms, including the human body, where it is an essential amino acid. In addition to l-hydroxylation, it is one of the amino acids encoded in DNA and is a key component of protein synthesis and building blocks of proteins. Sources: 5

The l-isomer form, the only form involved in protein synthesis, is necessary for normal human functioning and a key component in the production of proteins such as proteins, cell membranes and blood vessels. L – Phenylalanine can also be converted into the protein – it forms the amino acid tyrosine, a process that can lead to the formation of a number of different types of amino acids as well as the building blocks of many proteins. This amino acid, which is found in many proteins, such as hemoglobin, is normally easily converted into another amino acid in the human body – acid, tyrolysine, is indispensable in a human diet. Sources: 5

Phenylalanine is classified as an essential amino acid because it cannot be synthesized by the human body through chemical reactions from other compounds and must therefore be ingested in foodSources: 5

Phenylketonuria (PKU) is a rare autosomal recessive disorder caused by deficiency of the phenylalanine hydroxylase enzyme, which leads to the production of tyrosine, an essential amino acid for protein synthesis. A serious disorder, phenilket onuria, is the result of a genetic defect that inhibits a key enzyme required to convert phenolalanins into tyrorosins. Sources: 5, 7

Patients with PKU can develop a profound and irreversible mental disability that begins shortly after birth. This can increase the risk of heart disease, stroke, kidney failure and other serious health problems. Sources: 7

Phenylketonuria (PKU) is an inherited disease and, due to a congenital metabolic defect, one of the most difficult diseases to treat. It is caused by a deficiency of the enzyme phenylalanine hydroxylase (PAH), which converts the essential amino acid phenilalanine into tyrosine. This is inherited as an autosomal recessive trait and can lead to reduced phenolic levels in certain parts of the body, a key component of human metabolism. Sources: 4

If left untreated, PKU leads to deficiencies in phenylalanine and tyrosine as well as other metabolic disorders such as diabetes, heart disease, cancer and cardiovascular disease. Sources: 4

Phenylalanine uses the same active transport channel as tryptophan to cross the blood-brain barrier and disrupt serotonin production in large quantities. Persons with this disorder are known as phenylketonurics and must refrain from consuming phenilalin. Dietary restrictions can also be applied if the amino acid phenylonine is not properly metabolized. Sources: 0

Individuals suffering from PKU should monitor their protein intake to control the accumulation of phenylalanine in their body as it converts protein into its constituent amino acids. It is an amino acid needed to make proteins and brain chemicals such as serotonin, dopamine, norepinephrine and other neurotransmitters, as well as the neurotransmitter serotonin. The body needs it for health, but if it cannot make it, it will transform it into another, which means it needs the protein or brain chemistry or both to make it. Sources: 0, 6

Since norepinephrine affects mood, it is suggested to treat depression with various forms of phenylalanine. L – Phenolan, an antidepressant produced by the production of the neurotransmitter serotonin and other neurotransmitters such as dopamine, dopamine and serotonin. It is given to depressed people to treat depression, anxiety and other mental health problems, as well as as as an antidepressant. Sources: 3, 6

Preliminary research shows that L-phenylalanine improves mood in most of the depressed people studied and is effective against a range of mood swings – affecting substances including phenylethylamine and norepinephrine. Sources: 3

L – Phenylalanine is present in food, but there is a difference in its chemical composition between the two compounds. The difference lies in the molecular structure: D-Phenylalane is the synthesized form normally used for medical reasons, and D-PhenYLalanine is the synthetic form of phenylethylamine, the active ingredient in many medications. DLPA is an important component of the body’s immune system and a major cause of depression and anxiety. Sources: 2, 3

Phenylalanine is universally recognized as safe, and since it occurs naturally in foods, there is no reason to believe that it should have any side effects. Sources: 2

If you are one of the few people with phenylketonuria (PKU), you know that your body cannot process phenylalanine properly. It is the one amino acid that our body cannot produce itself, but must obtain from foodSources: 1, 2

Phenylalanine is a precursor of tyrosine and uses the same active transport channel as tryptophan to cross the blood-brain barrier. Together, they lead to adrenaline and norepinephrine, which are converted into serotonin, a brain chemical that relays nerve impulses. The brain uses these neurotransmitters to produce the neurotransmitter “nore pinephrine,” which promotes mental alertness and memory, lifts mood and suppresses appetite very effectively. Phenyl alanine disrupts serotonin production in large quantities and impairs the brain’s ability to process serotonin. Sources: 0, 1
