Factory Supply High Quality DL-Phenylalanine thiab L-Phenylalanine
Product Description
Phenylalanine yog ib qho tseem ceeb aromatic amino acid nyob rau hauv tib neeg (muab los ntawm cov zaub mov), Phenylalanine plays lub luag hauj lwm tseem ceeb nyob rau hauv lub biosynthesis ntawm lwm cov amino acids thiab yog ib qho tseem ceeb nyob rau hauv cov qauv thiab kev ua ntawm ntau cov proteins thiab enzymes. Phenylalanine hloov mus rau tyrosine, siv nyob rau hauv biosynthesis ntawm dopamine thiab norepinephrine neurotransmitters. Lub L-form ntawm Phenylalanine tau muab tso rau hauv cov proteins, thaum D-form ua cov tshuaj tua kab mob. Kev nqus ntawm ultraviolet hluav taws xob los ntawm Phenylalanine yog siv los ntsuas cov protein ntau.
L-phenylalanine yog L-enantiomer ntawm phenylalanine. Nws muaj lub luag haujlwm ua nutraceutical, micronutrient, Escherichia coli metabolite, Saccharomyces cerevisiae metabolite, cov nroj tsuag metabolite, algal metabolite, nas metabolite, tib neeg xenobiotic metabolite thiab EC 3.1.3.1 (alkaline phosphatase) inhibitor. Nws yog erythrose 4-phosphate / phosphoenolpyruvate tsev neeg amino acid, proteinogenic amino acid, phenylalanine thiab L-alpha-amino acid. Nws yog lub hauv paus conjugate ntawm L-phenylalaninium. Nws yog conjugate acid ntawm L-phenylalaninate. Nws yog ib qho enantiomer ntawm D-phenylalanine. Nws yog tautomer ntawm L-phenylalanine zwitterion.

Muaj nuj nqi
Qhov tseem ceeb amino acid L-phenylalanine (Phe) yog xav tau rau synthesis ntawm cov proteins, catecholamines, thiab melanin; Nws kuj yog ib qho tseem ceeb ua ntej ntawm cov amino acid L-tyrosine (Tyr).
