Ukusetshenziswa:
I-L-Phenylalanine (Isifinyezo sePhe) yi-amino acid ebalulekile futhi ukuphela kwendlela ye-phenylalanine etholakala kuma-protein. Ingenye yama-amino acid ayi-18, futhi ingenye yama-amino acid ayisishiyagalombili abalulekile emzimbeni womuntu.

Njengesengezo sokudla okunomsoco, i-L-phenylalanine ingabhekwa njengeqembu le-benzyl elifakwe esikhundleni seqembu le-methyl le-alanine, noma iqembu le-phenyl esikhundleni se-hydrogen yokugcina ye-alanine. Iningi emzimbeni yi-phenylalanine hydroxylase catalysis oxidation ku-tyrosine, kanye nokwenziwa nge-tyrosine ama-neurotransmitters abalulekile namahomoni, ukubamba iqhaza emzimbeni womzimba woshukela namafutha we-metabolism.

I-L-phenylalanine iyi-bioactive enamakha i-amino acid. I-amino acid edingekayo engeke yakwazi ukuzenzela yona ngabantu nezilwane. Kuyadingeka ukuthi umuntu adle i-2.2g L-phenylalanine nsuku zonke. Njengenye yama-amino acid ayisishiyagalombili adingekayo emzimbeni womuntu, isetshenziswe kabanzi embonini yezokwelapha kanye nokudla. Kuyisithako esibalulekile somjovo we-amino acid. Embonini yokulungisa ukudla, i-L-phenylalanine ingangezwa ekudleni okubhaka. Futhi umsoco we-phenylalanine ungathuthukiswa futhi nge-amido-carboxylation nge-glucide.

I-L-phenylalanine ingakhuphula iphunga lokudla futhi igcine ibhalansi yama-amino acid adingekayo. Emkhakheni wemithi, i-L-phenylalanine isetshenziswa njengendawo ephakathi kwemithi ethile ye-amino anticancer efana ne-formylmerphalanum nokunye. Iyasetshenziswa nokwenza i-adrenalin, thyroxin ne-melanin. Olunye uhlelo lokusebenza olubalulekile ukuhlanganisa i-aspartame ne-L-aspartic acid.

L - i-phenylalanine ingukudla okuyisisekelo okuluhlaza kokungeziwe kokudla - i-sweetener Aspartame (Aspartame). Njengenye yama-amino acid abalulekile emzimbeni, i-L-phenylalanine isetshenziselwa ukumpontshelwa kwe-amino acid kanye nezidakamizwa ze-amino acid embonini yezemithi.
