Solarachadh factaraidh DL-Phenylalanine agus L-Phenylalanine de chàileachd àrd
Tuairisgeul toraidh
Tha phenylalanine na amino-aigéad cùbhraidh riatanach ann an daoine (air a sholarachadh le biadh), tha prìomh àite aig Phenylalanine ann am biosynthesis amino-aigéid eile agus tha e cudromach ann an structar agus gnìomh mòran phròtainean agus enzymes. Tha phenylalanine air a thionndadh gu tyrosine, air a chleachdadh ann am biosynthesis de dopamine agus neurotransmitters norepinephrine. Tha an cruth L de Phenylalanine air a thoirt a-steach do phròtainean, fhad ‘s a tha an cruth D ag obair mar inneal-leaghaidh. Thathas a’ cleachdadh gabhail a-steach rèididheachd ultraviolet le Phenylalanine gus meud pròtain a thomhas.
Is e L-phenylalanine an L-enantiomer de phenylalanine. Tha àite aige mar nutraceutical, micronutrient, metabolite Escherichia coli, metabolite Saccharomyces cerevisiae, metabolite planntrais, metabolite algach, metabolite luchag, metabolite xenobiotic daonna agus EC 3.1.3.1 (alkaline phosphatase). Is e aminoideach teaghlach erythrose 4-phosphate / phosphoenolpyruvate, aminoideach proteinogenic, phenylalanine agus searbhag L-alpha-amino. Tha e na bhunait co-chuingealaichte de L-phenylalaninium. Is e searbhag conjugate de L-phenylalaninate a th’ ann. Tha e na enantiomer de D-phenylalanine. Tha e na thautomer de zwitterion L-phenylalanine.

Gnìomh
Tha feum air an aminoidid riatanach L-phenylalanine (Phe) airson synthesis pròtainean, catecholamines, agus melanin; Tha e cuideachd na ro-ruithear cudromach den aminoidid L-tyrosine (Tyr).
