Ubonelelo lweFactory eMgangathweni oPhezulu we-DL-Phenylalanine kunye ne-L-Phenylalanine
Ingcaciso yeMveliso
I-Phenylalanine yi-amino acid emnandi ebalulekileyo ebantwini (ebonelelwa kukutya), i-Phenylalanine idlala indima ephambili kwi-biosynthesis yezinye ii-amino acids kwaye ibalulekile kwisakhiwo kunye nokusebenza kweeprotheni ezininzi kunye ne-enzymes.I-Phenylalanine iguqulwa ibe yi-tyrosine, isetyenziswe kwi-biosynthesis ye-dopamine kunye ne-norepinephrine neurotransmitters.I-L-form ye-Phenylalanine ifakwe kwiiprotheni, ngelixa i-D-form isebenza njenge-painkiller.Ukufunxwa kwemitha ye-ultraviolet yiPhenylalanine isetyenziselwa ukulinganisa izixa zeprotheyini.
I-L-phenylalanine yi-L-enantiomer ye-phenylalanine.Inendima njenge-nutraceutical, i-micronutrient, i-Escherichia coli metabolite, i-Saccharomyces cerevisiae metabolite, i-metabolite yesityalo, i-algal metabolite, i-metabolite ye-mouse, i-metabolite ye-xenobiotic yomntu kunye ne-EC 3.1.3.1 inhibistorseal (i-EC 3.1.3.1).I-erythrose 4-phosphate / phosphoenolpyruvate intsapho ye-amino acid, i-proteinogenic amino acid, i-phenylalanine kunye ne-L-alpha-amino acid.Sisiseko se-conjugate se-L-phenylalaninium.I-asidi ye-conjugate ye-L-phenylalaninate.Yi-enantiomer ye-D-phenylalanine.Yitautomer ye L-phenylalanine zwitterion.

Umsebenzi
I-amino acid ebalulekileyo i-L-phenylalanine (Phe) iyadingeka ukuze kuhlanganiswe iiprotheni, i-catecholamines, kunye ne-melanin;ikwayi-precursor ebalulekileyo ye-amino acid L-tyrosine (Tyr).
