Feem ntau macromolecules yog polymers, uas yog cov chains ntev ntawm subunits hu ua monomers. Cov subunits no feem ntau zoo sib xws, thiab rau txhua qhov sib txawv ntawm cov polymers (thiab cov khoom muaj sia nyob hauv feem ntau) tsuas muaj li 40 - 50 hom monomers.
Qhov twg macromolecules yog polymers?
Carbohydrates, nucleic acids, thiab proteins feem ntau pom muaj ntev li polymers nyob rau hauv qhov. Vim tias lawv cov xwm txheej polymeric thiab lawv qhov loj (qee zaum loj!) loj, lawv raug cais raws li macromolecules, loj (macro-) molecules ua los ntawm kev koom nrog cov subunits me.
Puas yog macromolecules tib yam li polymer?
"Macromolecule" yog siv rau ib tus neeg molecules ntawm qhov hnyav molecular thiab "polymer" yog siv los txheeb xyuas cov khoom muaj xws li macromolecules"Polymer molecule" feem ntau tuaj yeem siv rau lub molecule uas nws cov qauv yog tsim los ntawm ntau yam rov ua dua los ntawm monomers.
Puas yog macromolecules monomers lossis polymers?
Proteins, carbohydrates, nucleic acids, thiab lipids yog plaub chav kawm loj ntawm biological macromolecules-loj molecules tsim nyog rau lub neej uas tsim los ntawm cov organic molecules me. Macromolecules yog tsim los ntawm ib chav tsev hu ua monomersuas tau koom nrog covalent bonds los tsim cov polymers loj.
Puas macromolecules ua polymers?
Feem ntau (tab sis tsis yog tag nrho) cov roj ntsha macromolecules yog cov polymers, uas yog cov molecules tsim los ntawm kev sib txuas ua kentau cov molecules me, hu ua monomers. … Monomers thiab polymers: Ntau lub me me monomer subunits ua ke los tsim cov carbohydrate polymer.
Pom zoo:
Rau tus yam ntxwv ntawm cov polymers?
Tus yam ntxwv ntawm cov khoom siv hluav taws xob hauv cov khoom siv polymer feem ntau yog hais txog kev ntsuas ntawm lub zog, elasticity, viscoelasticity, thiab anisotropy ntawm cov khoom siv polymeric …, plastics, lossis cov polymers nruj nyob ntawm lawv cov khoom siv kho tshuab .
Puas yog feem ntau tsim los ntawm metamorphism ntawm cov xuab zeb?
Metamorphism ntawm quartz-nplua nuj sandstone tsim quartzite (Fig. 8.9), ib qho nyuaj heev, nonfoliated metamorphic pob zeb muaj yuav luag tag nrho ntawm silica. 2. Metamorphism ntawm limestone thiab dolomite ua rau recrystallization ntawm calcite los ua marble (Fig .
Puas yog cov macromolecules puas tuaj yeem suav tias yog cov tshuaj organic?
Biological macromolecules tag nrho muaj cov pa roj carbon nyob rau hauv lub nplhaib lossis cov saw hlau, uas txhais tau hais tias lawv raug cais raws li cov organic molecules. Lawv feem ntau kuj muaj hydrogen thiab oxygen, nrog rau nitrogen thiab lwm yam me me .
Dab tsi ntawm cov spheres hauv qab no tau tsim los ntawm cov txheej txheem ntawm outgassing?
5. Cov pa roj tso tawm los ntawm cov hluav taws xob tawm hluav taws xob, tsim peb cov huab cua. Nco ntsoov tias vim roj av thiab dej vapor muaj tsawg tsawg kawg nkaus, lawv 'ntab' li tsim peb cov cua. 6 . Yuav ua li cas tshem tawm daim ntawv?
Thaum lub sijhawm tsim cov coke twg ntawm cov hauv qab no tau txais los ntawm cov khoom lag luam?
Coal tar: Nws tau los ua cov khoom lag luam hauv cov txheej txheem ntawm kev ua coke . Coke yog ib qho khoom los ntawm dab tsi? Cov lus tsis tsim nyog "coke" feem ntau yog hais txog cov khoom lag luam los ntawm qis-ash thiab qis-sulphur bituminous thee los ntawm txheej txheemhu ua coking.
