Daim ntawv thov
Ib qho purine nucleobase thiab ib feem ntawm DNA.Tshaj thoob plaws hauv cov tsiaj thiab cov ntaub so ntswg ua ke nrog niacinamide, d-ribose, thiab phosphoric acids;ib qho chaw ntawm nucleic acids thiab coenzymes, xws li codehydrase I thiab II, adenylic acid, coa laninedehydrase.Nws yog siv rau kev txiav txim siab microbial ntawm niacin;nyob rau hauv kev tshawb fawb ntawm heredity, kab mob, thiab mob cancer.enteric txheej thiab hauv zos antiseptic
Adenine, tseem hu ua 6-aminopurine, yog ib qho ntawm plaub nucleobases uas tsim DNA thiab RNA molecules, nrog rau cov tshuaj formula C5H5N5.Nws koom nrog hauv kev tsim ntau yam tseem ceeb xws li ATP thiab NADP hauv cov txheej txheem metabolic hauv lub cev.
Adenine yog ib feem ntawm nucleic acids thiab coenzymes, koom nrog hauv kev sib txuas ntawm DNA thiab RNA hauv lub cev, thiab tseem ceeb rau kev saib xyuas cov haujlwm metabolic ntawm lub cev.Nws lub luag haujlwm yog los txhawb kev loj hlob ntawm leukocytes thaum muaj qhov tsis txaus.
Synthesis
Adenine anabolism suav nrog ob qho tib si ab initio thiab kho cov txheej txheem hluavtaws.Txoj kev ab initio synthesis feem ntau yog nyob rau hauv daim siab thiab ua raws li ribose phosphate, aspartate, glycine, glutamine, thiab ib-carbon units.Purine nucleotides yog synthesized zuj zus nyob rau hauv lub hauv paus ntawm phosphoribose molecules, tsis yog los ntawm thawj synthesizing purine bases ib leeg thiab ces combining lawv nrog phosphoribose.Kev kho cov synthesis ntawm purine nucleotides feem ntau yog vim tsis muaj cov kab ke enzymatic rau ab initio synthesis ntawm purine nucleotides hauv qee cov ntaub so ntswg thiab lub cev ntawm lub cev, xws li lub hlwb thiab pob txha pob txha, kom tsuas yog txoj hauv kev no tuaj yeem ua tau, thiab qhov no. txoj kev txuag lub zog thiab qee cov amino acid noj thaum lub sij hawm ab initio synthesis.
