No tseem ceeb amino acids yog tsim los ntawm qabzib (alanine, arginine [los ntawm urea voj voog nyob rau hauv lub hlwb], asparagine, aspartate, cysteine, glutamate, glutamine, glycine, proline, thiab serine), tshwj tsis yog rautyrosine , uas yog tsim los ntawm phenylalanine.
Yuav ua li cas tsis tseem ceeb amino acids ua ke?
Cov amino acids tsis tseem ceeb yog synthesized los ntawm cov tshuaj tiv thaiv yooj yim heev, hos txoj hauv kev rau kev tsim cov amino acids tseem ceeb yog qhov nyuaj heev. Piv txwv li, qhov tsis tseem ceeb amino acids alanine thiab aspartate yog synthesized nyob rau hauv ib kauj ruam los ntawm pyruvate thiab oxaloacetate, feem.
Puas yog cov amino acids tsis tseem ceeb tuaj yeem tsim hauv daim siab?
Synthesis of Nonessential Amino Acids
Lub siab yog qhov chaw loj ntawm cov amino acid metabolism. Lub siab muaj enzymes xws li transaminases thiab yog lub luag hauj lwm rau cov tsis tseem ceeb amino acid synthesis los ntawm cov txheej txheem hu ua transamination.
Yuav ua li cas cov vitamin xav tau rau kev sib txuas ntawm cov amino acid tsis tseem ceeb?
Vitamin B6 ua coenzyme PLP, cuam tshuam nrog ntau dua 100 enzymes hauv ntau yam kev cuam tshuam metabolic xws li: Amino acid metabolism: PLP hloov pauv cov amino pawg (NH2) los ntawm cov amino acid mus rau keto acid uas ua rau cov synthesis ntawm cov amino acids tsis tseem ceeb.
Ntau npaum li cas cov amino acids tsis tseem ceeb tuaj yeem ua rau hauv lub cev?
Six amino acids yog qhov tsis tseem ceeb (dispensable) hauv tib neeg, txhais tau tias lawv tuaj yeem ua ke hauv cov khoom txaus hauv lub cev. Cov 6 no yog alanine, aspartic acid, asparagine, glutamic acid, serine, thiab selenocysteine (xws li 21st amino acid).
