L-Phenylalanine
Phenylalanine /ˌfɛnᵊlˈæləˌniːn/ (abbreviated as Phe or F)[2] is an α-amino acid with the formula C6H5CH2CH(NH2)COOH. This essential amino acid is classified as neutral, and nonpolar because of the inert and hydrophobic nature of the benzyl side chain. The L-isomer is used to biochemically form proteins, coded for by DNA. The codons for L-phenylalanine are UUU and UUC. Phenylalanine is a precursor for tyrosine, the monoamine neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), and the skin pigment melanin.
