Nkwanye ụlọ ọrụ dị elu DL-Phenylalanine na L-Phenylalanine
Nkọwa ngwaahịa
Phenylalanine bụ amino acid dị mkpa dị mkpa n'ime mmadụ (nke nri na-enye), Phenylalanine na-arụ ọrụ dị mkpa na biosynthesis nke amino acid ndị ọzọ ma dị mkpa na nhazi na ọrụ nke ọtụtụ protein na enzymes.A na-atụgharị Phenylalanine ka ọ bụrụ tyrosine, ejiri mee ihe na biosynthesis nke dopamine na norepinephrine neurotransmitters.Ụdị L-Phenylalanine na-etinye n'ime protein, ebe D-ụdị na-arụ ọrụ dị ka ihe mgbu.A na-eji Phenylalanine absorption radieshon ultraviolet iji chọpụta ọnụọgụ protein.
L-phenylalanine bụ L-enantiomer nke phenylalanine.Ọ nwere ọrụ dị ka ihe na-edozi ahụ, micronutrient, Escherichia coli metabolite, Saccharomyces cerevisiae metabolite, osisi metabolite, algal metabolite, òké metabolite, mmadụ xenobiotic metabolite na EC 3.1.3.1 (alkaline phosphatase) inhibit.Ọ bụ erythrose 4-phosphate/phosphoenolpyruvate amino acid, amino acid proteinogenic, phenylalanine na L-alpha-amino acid.Ọ bụ njikọ njikọ nke L-phenylalaninium.Ọ bụ conjugate acid nke L-phenylalaninate.Ọ bụ enantiomer nke D-phenylalanine.Ọ bụ tautomer nke L-phenylalanine zwitterion.
