7636-28-4 Usage
General Description
2-amino-4-phenyl-butanoic acid, also known as L-Phenylalanine, is an essential amino acid that is important for the biosynthesis of proteins. It is a precursor for the neurotransmitters tyrosine, dopamine, epinephrine, and norepinephrine, making it crucial for normal neurological function. L-Phenylalanine is found in a wide variety of protein-rich foods such as meat, fish, eggs, dairy products, and certain plant-based sources like nuts and seeds. It is also available as a dietary supplement and is sometimes used in the treatment of phenylketonuria, depression, and attention-deficit hyperactivity disorder. However, excessive intake of L-Phenylalanine can have negative health effects, particularly for individuals with certain medical conditions.
