N-Cbz-glycyl-glycyl-D-phenylalanine serves as a cleavable ADC (antibody-drug conjugate) linker.

4-Amino-D-phenylalanine ([D-Phe(4-NH2)]) is a cyclic pentapeptide that inhibits the binding of CXCL12 to CXCR4 in FC131, with an IC50 value of 0.1 μM.

D-Phenylalanine 4-nitroanilide is a reagent used in biochemical reactions.

(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.

L-Tyrosine-13C9,15N is intended for use as an internal standard for the quantification of L-tyrosine by GC- or LC-MS. L-Tyrosine is a non-essential amino acid.1It is produced by hydroxylation of phenylalanine by phenylalanine hydroxylase but can also be obtained from dietary sources or degradation of endogenous proteins, resulting in L-tyrosine release.1,2L-Tyrosine is a precursor in the biosynthesis of catecholamine neurotransmitters, melanins, and thyroid hormones.3Plasma, skeletal muscle, and erythrocyte levels of L-tyrosine are decreased in patients with chronic kidney disease.1 1.Kopple, J.D.Phenylalanine and tyrosine metabolism in chronic kidney failureJ.

L-Phenylalanine-15N ((S)-2-Amino-3-phenylpropionic acid-15N) is the 15N-labeled L-Phenylalanine. L-Phenylalanine is an essential amino acid isolated from Escherichia coli . L-Phenylalanine is a α2δ subunit of voltage-dependent Ca + channels antagonist with a K i of 980 nM. L-phenylalanine is a competitive antagonist for the glycine- and glutamate-binding sites of N-methyl-D-aspartate receptors (NMDARs) ( K B of 573 μM ) and non-NMDARs , respectively. L-Phenylalanine is widely used in the production of food flavors and pharmaceuticals.

L-Phenylalanine (Standard) is an essential alpha-amino acid used as a standard for quantitative analysis.L-Phenylalanine is an agonist of GPR142 and promotes insulin secretion, which is closely related to glucose metabolism and diabetes research. L-Phenylalanine is an agonist of GPR142 and promotes insulin secretion, which has been implicated in studies of glucose metabolism and diabetes. May indirectly regulate N-methyl-D-aspartate receptors (NMDA receptors) by affecting dopamine levels.
