Qhov Tseem Ceeb Qhov txawv - Pyruvate vs Pyruvic Acid

Cov ntsiab lus Pyruvate thiab Pyruvic acid feem ntau siv sib hloov; Txawm li cas los xij, muaj qhov sib txawv ntawm lawv: Pyruvic acid yog cov kua qaub, uas qhia tau hais tias nws tuaj yeem tso cov hydrogen ion thiab khi nrog cov tshuaj zoo sodium lossis potassium ion thiaj li tsim tau cov kua qaub ntsev, tseem hu ua pyruvate. Hauv lwm lo lus, pyruvate yog ntsev lossis ester ntawm pyruvic acid. Qhov no yog qhov sib txawv tseem ceeb ntawm pyruvate thiab pyruvic acid thiab ob qho tib si tshuaj yog siv rau hauv txoj kev lom neeg thiab metabolic, tab sis tseem muaj kev sib raug zoo.

YPyruvic Acid yog dab tsi?

Pyruvic acid ua lub luag haujlwm tseem ceeb hauv tib neeg cov metabolism. Piv txwv li, lub zog yog muab rau cov hlwb nyob los ntawm cellular aerobic respiration los yog pyruvic acid yog fermented los tsim lactic acid los ntawm fermentation. Pyruvic acid yog cov kua hauv qhov xwm txheej, thiab nws tsis muaj xim thiab muaj ntxhiab tsw zoo li acetic acid. Nws yog ib tug tsis muaj zog acid, thiab nws yog yaj nyob rau hauv dej. Cov tshuaj formula ntawm pyruvic acid yog (CH _{3 COCOOH), thiab nws raug suav hais tias yog daim ntawv yooj yim tshaj plaws ntawm alpha-keto acids nrog carboxylic acid thiab ketone functional pawg. Ntxiv rau qhov ntawd, pyruvic acid yog carboxylic acid uas tsis muaj zog li inorganic acids zoo li hydrochloric acid.}

YPyruvate yog dab tsi?

Pyruvate yog lub hauv paus ntawm pyruvic acid thiab nws cov tshuaj formula yog CH3COCOO^{-Hauv lwm lo lus, pyruvate yog anion tsim los ntawm pyruvic acid. Qhov sib txawv tseem ceeb ntawm pyruvic acid thiab pyruvate yog tias hydrogen atom ntawm pawg carboxylic acid tau disassociated, los yog nws tau raug tshem tawm. Qhov no muab cov pab pawg neeg carboxylate tsis zoo rau pyruvate. Vim qhov tsis muaj zog acidity ntawm pyruvic acid, nws yooj yim dissociates hauv dej thiab yog li tsim pyruvate. Pyruvate yog ib qho tshuaj tseem ceeb hauv tib neeg cov metabolism thiab biochemistry. Pyruvate koom nrog hauv cov metabolism hauv qabzib thiab tseem hu ua glycolysis. Hauv cov txheej txheem glycolysis, ib qho molecule ntawm qabzib tau tawg mus rau hauv ob lub molecules ntawm pyruvate, uas tom qab ntawd siv cov tshuaj tiv thaiv ntxiv los tsim lub zog.}

Qhov txawv ntawm Pyruvate thiab Pyruvic acid yog dab tsi?

Pyruvate thiab pyruvic acid tuaj yeem muaj cov tshuaj lom neeg sib txawv thiab qee qhov ua haujlwm zoo. Cov kev sib txawv no tau tham ntawm no.
