Qhov sib txawv tseem ceeb ntawm ascorbate thiab ascorbic acid yog ascorbic acid yog cov organic compound. Lub caij no, ascorbate yog anion tsim los ntawm ascorbic acid.
Ascorbic acid yog dav paub tias yog vitamin C. Nws ib txwm tshwm sim hauv ntau cov khoom noj xws li txiv hmab txiv ntoo thiab zaub, thiab nws kuj yog siv los ua zaub mov ntxiv. Lub sij hawm ascorbate yog hais txog cov anion ntawm ascorbic acid uas tsim thaum ib tug hydrogen atom raug tshem tawm raws li ib tug hydrogen ion. Tsis tas li ntawd, peb tuaj yeem sau npe cov khoom sib xyaw uas muaj cov anion no sib sau ua ascorbates.
Ascorbate yog dab tsi?
Ascorbate yog anion ntawm ascorbic acid uas tsim los ntawm kev tshem tawm cov hydrogen ion los ntawm ib qho ntawm -OH pawg muaj nyob hauv ascorbic acid. Yog li ntawd, nws yog conjugate puag ntawm ascorbic acid. Ntxiv mus, L-isomer ntawm ascorbic acid yog ntau tshaj li D-isomer; Li no, ascorbate peb pom feem ntau yog L-ascorbate. Cov tshuaj formula ntawm ascorbate anion yog C6H7O6–Kev tsim ntawm ascorbate anion los ntawm ascorbic acid molecule koom nrog kev xaiv deprotonation ntawm pawg 3-hydroxyl.

Muaj ntau yam kev siv sib txawv ntawm ascorbate; Nws yuav tsum tau muaj ntau yam metabolic tshua nyob rau hauv cov tsiaj, ib qho tseem ceeb raws li ib tug tib neeg metabolite, tseem ceeb raws li ib tug cofactor thiab kuj yog ib qho tseem ceeb raws li ib tug dej-soluble vitamin.
YAscorbic Acid yog dab tsi?
Ascorbic acid yog cov organic compound peb paub feem ntau yog vitamin C. Cov vitamin no muaj nyob hauv ntau qhov khoom noj, thiab nws raug muag raws li kev noj haus ntxiv thiab. Cov tshuaj formula ntawm cov compound yog C6H8O6 Nws yog ib qho nruab nrab (tsis muaj qhov tsis zoo. los yog tus nqi zoo). Tsis tas li ntawd, cov molar loj ntawm cov compound yog 176 g / mol.
Tsis tas li ntawd, vitamin C yog qhov tseem ceeb hauv peb lub cev. Nws pab kho cov ntaub so ntswg thiab hauv kev tsim cov tshuaj neurotransmitters. Ntxiv mus, peb lub cev tiv thaiv kab mob xav tau qhov sib xyaw no rau nws txoj haujlwm raug. Ntxiv nrog rau cov no, ascorbic acid kuj yog ib qho tshuaj antioxidant.

Txawm li cas los xij, qhov tsis txaus ntawm cov vitamin C tuaj yeem ua rau muaj kab mob hu ua scurvy; Yog tias tsis muaj qhov xav tau ntawm ascorbic acid hauv peb lub cev, collagen yuav tsis ruaj khov, thiab qee qhov kev cuam tshuam enzymatic tsis tuaj yeem ua thaum tsis muaj ascorbic acid. Tsis tas li ntawd, muaj qhov tsis txaus ntseeg ntawm qhov mob toxicity vim yog overdose ntawm ascorbic acid. Qhov no yog vim feem ntau ntawm ascorbic acid yog tawm los ntawm cov zis. Txawm li cas los xij, koob tshuaj ntau dua ntawm lub plab khoob tuaj yeem ua rau plab zom mov.
Qhov txawv ntawm Ascorbate thiab Ascorbic Acid yog dab tsi?
Ascorbic acid yog vitamin C. Nws yog ib feem ntawm ntau yam khoom noj. Ascorbate yog cov anion tsim los ntawm ascorbic acid. Yog li, ascorbate yog lub hauv paus conjugate ntawm ascorbic acid. Qhov sib txawv tseem ceeb ntawm ascorbate thiab ascorbic acid yog ascorbic acid yog cov organic compound. Lub caij no, ascorbate yog cov anion tsim los ntawm ascorbic acid. Ntxiv mus, cov tshuaj formula ntawm ascorbate yog C6H7O6–thaum cov tshuaj formula ntawm ascorbic acid yog C6H8O6 Tsis tas li ntawd, cov ascorbate anion yog tsim los ntawm kev xaiv deprotonation ntawm 3-hydroxyl pawg ntawm ascorbic acid molecule.
Muaj ntau yam kev siv sib txawv ntawm ascorbate; Nws yog qhov yuav tsum tau rau ntau qhov sib txawv metabolic nyob rau hauv cov tsiaj, ib qho tseem ceeb raws li ib tug tib neeg metabolite, tseem ceeb raws li ib tug cofactor thiab yog ib qho tseem ceeb raws li ib tug dej-soluble vitamin. Thaum xav txog vitamin C los yog ascorbic acid, muaj ntau yam kev siv xws li kho cov ntaub so ntswg thiab nyob rau hauv zus tau tej cov neurotransmitters. Ntxiv mus, peb lub cev tiv thaiv kab mob xav tau qhov sib xyaw no rau nws txoj haujlwm raug. Ntxiv nrog rau cov no, ascorbic acid yog cov paub zoo antioxidant.
Cov ntawv qhia hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm ascorbate thiab ascorbic acid.
Summary – Ascorbate vs Ascorbic Acid
Ascorbic acid yog vitamin C. Nws yog ib feem ntawm ntau yam khoom noj. Ascorbate yog cov anion tsim los ntawm ascorbic acid. Yog li, ascorbate yog lub hauv paus conjugate ntawm ascorbic acid. Qhov sib txawv tseem ceeb ntawm ascorbate thiab ascorbic acid yog ascorbic acid yog cov organic compound, hos ascorbate yog anion tsim los ntawm ascorbic acid.
