Fabriek Supply High Quality DL-Phenylalanine en L-Phenylalanine
produkt Omskriuwing
Phenylalanine is in essensjele aromaatyske aminosoer yn minsken (fersoarge troch iten), Phenylalanine spilet in wichtige rol yn 'e biosynteze fan oare aminosoeren en is wichtich yn' e struktuer en funksje fan in protte aaiwiten en enzymen.Phenylalanine wurdt omboud ta tyrosine, brûkt yn de biosynteze fan dopamine en norepinephrine neurotransmitters.De L-foarm fan Phenylalanine is yn aaiwiten opnommen, wylst de D-foarm fungearret as in pynstiller.Absorpsje fan ultraviolette strieling troch Phenylalanine wurdt brûkt om proteïnebedrach te kwantifisearjen.
L-phenylalanine is it L-enantiomeer fan phenylalanine.It hat in rol as nutraceutical, in mikronutrient, in Escherichia coli metabolite, in Saccharomyces cerevisiae metabolite, in plant metabolite, in algen metabolite, in mûs metabolite, in minsklike xenobiotic metabolite en in EC 3.1.3.1 (alkaline phosphatase) inhibitor.It is in erythrose 4-phosphate / phosphoenolpyruvate famylje amino acid, in proteinogenic amino acid, in phenylalanine en in L-alpha-amino acid.It is in konjugatbasis fan in L-phenylalaninium.It is in konjugatsoer fan in L-phenylalaninate.It is in enantiomeer fan in D-phenylalanine.It is in tautomer fan in L-phenylalanine zwitterion.

Funksje
De essinsjele aminosoer L-phenylalanine (Phe) is nedich foar de synteze fan aaiwiten, catecholamines, en melanine;it is ek in wichtige foarrinner fan it aminosoer L-tyrosine (Tyr).
