Phenylalanine ball and stick model spinning. Phenylalanine (symbol Phe or F) [3] is an essential α-amino acid with the formula C 9 H 11 NO 2.It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine.

Phenylalanine hydroxylase (PAH) (EC 1.14.16.1) is an enzyme that catalyzes the hydroxylation of the aromatic side-chain of phenylalanine to generate tyrosine.PAH is one of three members of the biopterin-dependent aromatic amino acid hydroxylases, a class of monooxygenase that uses tetrahydrobiopterin (BH 4, a pteridine cofactor) and a non-heme iron for catalysis.
α-Methylphenylalanine (α-MePhe or AMPA) is an artificial amino acid and a phenethylamine and amphetamine derivative. [1] It is the α-methylated analogue of phenylalanine, the precursor of the catecholamine neurotransmitters, and the amino acid analogue of amphetamine (α-methylphenethylamine), a psychostimulant and monoamine releasing agent.
D-Phenylalanine is a psychostimulant and selective norepinephrine releasing agent (NRA) or norepinephrine-preferring norepinephrine–dopamine releasing agent (NDRA). [ 1 ] [ 2 ] The EC 50 Tooltip half-maximal effective concentration values of D -phenylalanine for monoamine release are 106 nM for norepinephrine, 1,355 nM for dopamine , and ...
In mammals it is created from -lactate and L-phenylalanine by the cytosol nonspecific dipeptidase (CNDP2) protein. [1] It is classified as N-acyl-alpha-amino acid and pseudodipeptide. [11] It has also been reported that as an additive, N-L-lactoyl phenylalanine improves the taste of food, conferring an umami flavor. [12]
The cloverleaf model of tRNA is a model that depicts the molecular structure of tRNA. [1] The model revealed that the chain of tRNA consists of two ends—sometimes called "business ends"—and three arms. Two of the arms have a loop, D-loop (dihydro U loop) and Tψc-loop with a ribosome recognition site.
