Phepelo ya Femethari ya Boleng bo Phahameng DL-Phenylalanine le L-Phenylalanine
Tlhaloso ea Sehlahisoa
Phenylalanine ke amino acid ea bohlokoa e nkhang hamonate bathong (e fanoang ke lijo), Phenylalanine e na le karolo ea bohlokoa ho biosynthesis ea li-amino acid tse ling 'me e bohlokoa sebopehong le tšebetsong ea liprotheine tse ngata le li-enzyme. Phenylalanine e fetoleloa ho tyrosine, e sebelisoang ho biosynthesis ea dopamine le li-neurotransmitters tsa norepinephrine. Mofuta oa L oa Phenylalanine o kenyelelitsoe liprotheine, ha mofuta oa D o sebetsa joalo ka sebolaya-bohloko. Ho monya mahlaseli a ultraviolet ke Phenylalanine ho sebelisoa ho lekanya palo ea liprotheine.
L-phenylalanine ke L-enantiomer ea phenylalanine. E na le karolo ea phepo e nepahetseng, micronutrient, Escherichia coli metabolite, Saccharomyces cerevisiae metabolite, semela sa metabolite, algal metabolite, mouse metabolite, xenobiotic metabolite ea motho le EC 3.1.3.1 inhibiphataseal inhibiphataseal. Ke erythrose 4-phosphate/phosphoenolpyruvate family amino acid, proteinogenic amino acid, phenylalanine le L-alpha-amino acid. Ke setsi sa conjugate sa L-phenylalaninium. Ke conjugate acid ea L-phenylalaninate. Ke enantiomer ea D-phenylalanine. Ke tautomer ea L-phenylalanine zwitterion.
