phenylalanine

L-Phenylalanine (3-Phenyl-L-alanine) is an essential amino acid and the precursor of the amino acid tyrosine, acts as an antagonist at α2δ calcium channels.

D-Phenylalanine, a necessary aromatic amino acid, is a precursor of thyroxine, dopamine, melanin, and noradrenaline (norepinephrine).

N-Acetyl-L-phenylalanine (N-Ac-Phenylalanine) is an essential amino acid produced for medical, feed, and nutritional applications. It appears in large amount in urine of patients with phenylketonuria which is a human genetic disorder due to the lack of phenylalanine hydroxylase, the enzyme necessary to metabolize phenylalanine to tyrosine. Acetylphenylalanine is a product of enzyme phenylalanine N-acetyltransferase in the pathway phenylalanine metabolism.

Phenylalanine N,N,N-Tri-Me betaine is a useful organic compound for research related to life sciences. The catalog number is T126137 and the CAS number is 125982-49-2.

Leucyl-phenylalanine (H-LEU-PHE-OH) is a dipeptide compound that can be used for protein synthesis.

4-Amino-L-phenylalanine (4APhe) is a TcCA activator, useful for studying protozoan pathogen infections.

N-Lactoyl-Phenylalanine (Lac-Phe) is a peptide coupling of lactic acid and phenylalanine, one of the metabolites in acute exercise, which can be used in the study of obesity and metabolism-related diseases.

DL-Phenylalanine is a natural product

Phenylalanine betaine is a Standard reference.

Benzoylphenylalanine (LBPA) can be used as a photoaffinity peptide inactivator.

Alanylphenylalanine (Ala-phe) is a compound isolated from the brainstem of calves.

N-Benzyloxycarbonyl-N-Glycylphenylalanine is a useful organic compound for research related to life sciences and the catalog number is T131549.

N-benzyl-N-methylphenylalanine is a useful organic compound for research related to life sciences and the catalog number is T131578.

L-Tyrosine ((S)-Tyrosine) is a naturally occurring tyrosine and is synthesized in vivo from L-phenylalanine, considered a non-essential amino acid. L-Tyrosine(L-p-Tyrosine) is the levorotatory isomer of the aromatic amino acid tyrosine.

Phenyl acetate (Acetic acid phenyl ester) is an aromatic fatty acid metabolite of phenylalanine with potential antineoplastic activity. Naturally occurring in mammals, phenylacetate induces differentiation, growth inhibition, and apoptosis in tumor cells.

DL-Dopa is a phenylalanine beta-hydroxylated derivative.

Phenylpyruvic acid (3-Phenylpyruvic acid) is a keto-acid that is an intermediate or catabolic byproduct of phenylalanine metabolism. It has a slight honey-like odor. Levels of phenylpyruvate are normally very low in blood or urine. High levels of phenylpyruvic acid can be found in the urine of individuals with phenylketonuria (PKU), an inborn error of metabolism.

(S)-2-Hydroxy-3-phenylpropanoic acid (L-(−)-3-Phenyllactic acid) is a chiral aromatic compound involved in phenylalanine metabolism. It is likely produced from phenylpyruvate via lactate dehydrogenase. The D-form is derived from bacterial sources, while the L-form is endogenous. Phenyllactate levels are normally very low in blood or urine, but high levels indicate phenylketonuria (PKU) and hyperphenylalaninemia (HPA). PKU is due to a deficiency of phenylalanine hydroxylase (PAH), causing phenylalanine to convert to phenylpyruvic acid rather than tyrosine.

H-Phe-Phe-OH is a dipeptide composed of two phenylalanine (an essential amino acid and precursor to tyrosine) units linked together.

DL-o-Tyrosine is a metabolite of Phenylalanine and is a precursor in the formation of catecholamines. It is used as biomarkers of protein oxidative damage in β-thalassemia.

2-Amino-5-phenylpyridine is a heterocyclic aromatic amine formed by pyrolysis of phenylalanine in proteins, found in broiled sardines, and is considered potentially carcinogenic.

p-Cresyl Sulfate is the major uremic toxin present in the blood of patients with chronic kidney disease and is derived from the metabolites of tyrosine and phenylalanine in the liver.

Aureusimine B, also known as phevalin, is a natural pyrazinone produced by certain fungi and by Staphylococcus spp., including S. aureus. Its synthesis appears to be initiated by a conserved nonribosomal peptide synthetase that creates a dipeptide (phenylalanine-valine) aldehyde, which then undergoes cyclization and oxidation. Aureusimine B inhibits calpain in a casein hydrolysis assay (IC50 = 1.3 μM), contributes to S. aureus infection in mice, and alters human keratinocyte gene expression.

Phenylalanylalanine (H-Phe-Ala-OH) is a dipeptide composed of phenylalanine and alanine, produced during incomplete protein digestion or catabolism [1].
