LP15416-8   Arginine
Arginine (symbol Arg or R) is an amino acid. The L-form (L-arginine) is one of the 20 most common natural amino acids. In mammals, arginine is classified as a conditionally essential amino acid, depending on the developmental stage and health status of the individuals. Infants are unable to effectively synthesize arginine, making it nutritionally essential for them. Adults, however, are able to synthesize arginine in the urea cycle. The body uses arginine for a variety of purposes, including boosting immune system function and improving blood flow. Arginine sources include diet, medication, and/or nutritional supplements. Dietary sources include meat, dairy products and fish. Source: Medline Plus, MedlinePlus: L-arginine

LP70160-4   Phenylalanine
Phenylalanine is an essential alpha-amino acid. It exists in two forms, a D and an L form, which are enantiomers (mirror-image molecules) of each other. It has a benzyl side chain and its name comes from its chemical structures that consists of a phenyl group substituted for one of the hydrogens in the side chain of alanine. Because of its phenyl group, phenylalanine is an aromatic compound that at room temperature exists as a white, powdery solid. L -phenylalanine (LPA) is an electrically-neutral amino acid and its enantiomer, D -phenylalanine (DPA), can be synthesized artificially. L -phenylalanine can also be converted into L -tyrosine, another one of the twenty protein-forming amino acids. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
