Factory Supply High Quality DL-Phenylalanine uye L-Phenylalanine
Product Description
Phenylalanine inokosha inonhuhwirira amino acid muvanhu (inopihwa nechikafu), Phenylalanine inoita basa rakakosha mu biosynthesis yemamwe amino acids uye yakakosha mukuumbwa uye kushanda kwemapuroteni akawanda nema enzymes. Phenylalanine inoshandurwa kuita tyrosine, inoshandiswa mu biosynthesis ye dopamine uye norepinephrine neurotransmitters. Iyo L-fomu yePhenylalanine inosanganiswa mumapuroteni, nepo D-fomu inoshanda senge painkiller. Kutorwa kwemwaranzi yeultraviolet nePhenylalanine inoshandiswa kuyera huwandu hweprotein.
L-phenylalanine ndiyo L-enantiomer ye phenylalanine. Iine basa rekudya, micronutrient, Escherichia coli metabolite, Saccharomyces cerevisiae metabolite, plant metabolite, algal metabolite, mouse metabolite, munhu xenobiotic metabolite uye EC 3.1.3.1 inhibistorseal (EC 3.1.3.1). Ndiyo erythrose 4-phosphate/phosphoenolpyruvate mhuri amino acid, proteinogenic amino acid, phenylalanine uye L-alpha-amino acid. Ndiyo conjugate base yeL-phenylalaninium. Iyo conjugate acid yeL-phenylalaninate. Ndiyo enantiomer yeD-phenylalanine. Iyo tautomer yeL-phenylalanine zwitterion.
