Cov pab pawg ua haujlwm yog txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj khov dua li cov pob txha carbon thiab muaj feem yuav koom nrog cov tshuaj tiv thaiv.
Kuj paub, dab tsi yog pab pawg ua haujlwm thiab vim li cas lawv tseem ceeb?
Cov pab pawg ua haujlwm yog tseem ceeb inchemistry vim lawv yog ib feem ntawm cov molecule uas muaj peev xwm ntawm cov yam ntxwv tshwm sim. Lawv Yog li ntawd, txiav txim siab cov khoom thiab chemistry ntawm ntau cov organiccompounds.
Tus R sawv cev dab tsi hauv pab pawg ua haujlwm? R txhais tau tias Radical Pab pawg ”lub ntsiab lus pab pawg nyob rau hauv uas ib tug carbon los yog hydrogen atom yog txuas mus rau tus so ntawm lub molecule. Nws qhia tau hais tias anorganic saw deprieved ntawm nws pab pawg ua haujlwm.
Kuj paub yog, dab tsi yog ib pab pawg ua haujlwm thiab nws feem ntau muaj dab tsi?
A pab pawg ua haujlwm yog ib feem ntawm cov moleculehat yog ib tug recognizable/classified pab pawg ntawm bound atoms. Inorganic chemistry nws muaj ntau heev pom cov molecules muaj feem ntau ntawm cov pob txha carbon nrog pab pawg ua haujlwm txuas rau cov saw hlau.
Dab tsi ua haujlwm pab pawg tseem ceeb tshaj plaws rau lub zog ntawm tes?
Nrog plaub electronegative oxygen atoms, phosphate pab pawg yog heev reactive, thiab hloov ntawm phosphate pab pawg los ntawm ib lub molecule mus rau lwm tus xa zog tshuaj tiv thaiv tochemical. ATP, qhov tseem ceeb zog cov cab kuj nyob rau hauv hlwb, yog tsim los ntawm peb phosphate pab pawg bonded insuccession.

Vim li cas cov pab pawg carbonyl tseem ceeb?
Lawv tuaj yeem pom hauv ntau pawg ua haujlwm sib txawv, xws li aldehydes, ketones, esters, thiab ntau ntxiv. Ib pawg carbonyl tuaj yeem ua rau kom lub melting lossis boiling point ntawm lub compound. Nws tau piav raws li polar thiab reactive, thiab cov nqi tsis zoo thiab zoo ntawm carbonyl pab txhawb rau polarity
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Dab tsi yog qhov sib txawv tseem ceeb ntawm kev xaiv cov phooj ywg thiab kev xaiv pab pawg?
Kev xaiv Kin, hais lus ntxhib, yog kev xaiv ntawm qhov sib txawv ntawm qhov tsis ncaj ncees (rb ≠ 0) uas tshwm sim hauv cov neeg siab-K (cov pej xeem uas muaj kev sib raug zoo ntawm cov txheeb ze); whereas kev xaiv pab pawg, kwv yees hais lus, yog kev xaiv ntawm qhov sib txawv ntawm qhov tsis muaj zog (rb ≠ 0) uas tshwm sim hauv cov neeg siab-G (cov pej xeem
Dab tsi ua haujlwm pab pawg tseem ceeb tshaj plaws rau lub zog ntawm tes?
Nrog plaub lub electronegative oxygen atoms, phosphate pawg yog cov reactive heev, thiab kev hloov ntawm ib pab pawg phosphate los ntawm ib tug molecule mus rau lwm tus muab lub zog rau cov tshuaj tiv thaiv. ATP, lub luag haujlwm tseem ceeb hauv lub hlwb, yog tsim los ntawm peb pawg phosphate sib koom ua ke
Yuav ua li cas cov hlwb tshwj xeeb tsim los ua cov haujlwm tseem ceeb hauv ntau cov kab mob?
Multicellular kab mob ua lawv txoj kev ua neej los ntawm kev faib ua haujlwm. Lawv muaj cov hlwb tshwj xeeb uas ua haujlwm tshwj xeeb. Lub Colonial Theory qhia tias kev koom tes ntawm cov hlwb ntawm tib hom coj mus rau kev loj hlob ntawm cov kab mob multicellular
