Ukusetyenziswa:
I-L-Phenylalanine (Isifinyezo sePhe) yi-amino acid ebalulekileyo kwaye kuphela kwendlela ye-phenylalanine efumaneka kwiiproteni. Inye ye-18 yee-amino acid eziqhelekileyo, kunye nenye yee-amino acid ezisibhozo emzimbeni womntu.

Njengokongezwa kwesondlo, i-L-phenylalanine inokujongwa njengeqela le-benzyl endaweni yeqela le-methyl ye-alanine, okanye iqela le-phenyl endaweni yesiphelo se-hydrogen ye-alanine. Uninzi emzimbeni yi-phenylalanine hydroxylase catalysis oxidation kwi-tyrosine, kunye nokwenziwa nge-tyrosine ii-neurotransmitters ezibalulekileyo kunye neehormoni, zokuthatha inxaxheba emzimbeni womzimba weswekile kunye ne-fat metabolism.

L-phenylalanine yi-bioactive aromatic amino acid. Yi-amino acid eyimfuneko engenakho ukuzenzela ngokwakho ngabantu nakwizilwanyana. Kuyimfuneko ukuba umntu athathe i-2.2g L-phenylalanine yonke imihla. Njengenye yee-amino acid ezisibhozo eziyimfuneko emzimbeni womntu, ibisetyenziswa ngokubanzi kumayeza okuxuba kunye nokutya. Yinto ebalulekileyo yenaliti yeamino acid. Kwimveliso yokulungisa ukutya, i-L-phenylalanine inokongezwa kukutya okubhaka. Kwaye isondlo se-phenylalanine sinokuphuculwa kunye ne-amido-carboxylation kunye ne-glucide.

I-phenylalanine inokuphucula ukutya kunye nokugcina ii-amino acid ezifanelekileyo. Kwimizi-mveliso yamayeza, i-L-phenylalanine isetyenziswa njengophakathi kwezinye ii-amino anticancer pharmaceuticals ezinje nge-formylmerphalanum kunye nokunye. Esinye isicelo esibalulekileyo kukudibanisa i-aspartame kunye ne-L-aspartic acid.

L-phenylalanine yeyona nto iphambili ekrwada yokutya okuncomekayo-i-sweetener Aspartame (Aspartame). Njengenye yeeamino acid emzimbeni, i-L-phenylalanine isetyenziselwa ikakhulu utofelo-amino acid kunye neziyobisi zeamino acid kwishishini lamayeza.
