D-Phenylalanine is distributed to the various tissues of the body via the systemic circulation. It appears to cross the blood–brain barrier less efficiently than L-phenylalanine, and so a small amount of an ingested dose of D-phenylalanine is excreted in the urine without penetrating the central nervous system. [24] L-Phenylalanine is an ...

D-Phenylalanine (DPA, D-Phe), sold under the brand names Deprenon, Sabiben, and Sabiden, is an enantiomer of phenylalanine which is described as an antidepressant and is marketed as a prescription drug for medical use in Argentina. [1] [2] The medication has been marketed since at least the 1970s [3] and continued to be available by the 2000s. [1]
Phenylalanine: F Phe Essential for humans, phenylalanine, tyrosine, and tryptophan contain a large, rigid aromatic group on the side chain. These are the biggest amino acids. Like isoleucine, leucine, and valine, these are hydrophobic and tend to orient towards the interior of the folded protein molecule. Phenylalanine can be converted into ...
Most common among natural products is the amino acid phenylalanine, which contains a phenyl group. A major product of the petrochemical industry is " BTX " consisting of benzene, toluene, and xylene - all of which are building blocks for phenyl compounds.
Diphenylalanine is a term that has recently been used to describe the unnatural amino acid similar to the two amino acids alanine and phenylalanine.It has been used for the synthesis of pseudopeptide analogues which are capable of inhibiting certain enzymes.
d-DOPA (D-3,4-dihydroxyphenylalanine; dextrodopa) is similar to L-DOPA (levodopa), but with opposite chirality. Levo - and dextro - rotation refer to a molecule's ability to rotate planes of polarized light in one or the other direction.
