Monomers yog cov molecules me me, feem ntau cov organic, uas tuaj yeem koom nrog lwm cov molecules zoo sib xws los tsim cov molecules loj heev, lossis polymers . Tag nrho cov monomers muaj peev xwm tsim cov tshuaj tiv thaiv rau yam tsawg kawg yog ob qho tib si monomer molecules. Polymers yog chains nrog ib tug unspecified tooj ntawm monomeric units.
Yog li ntawd, yuav ua li cas lub monomer los ua ib tug polymer?
Monomers yog me me molecules uas yuav ua koom ua ke nyob rau hauv ib tug rov ua qauv los tsim ntau complex molecules hu ua polymers . Monomers daim ntawv polymers los ntawm kev tsim cov tshuaj bonds los yog khi supramolecularly los ntawm cov txheej txheem hu ua polymerization.
Tsis tas li ntawd, 4 hom monomers yog dab tsi? Qhov tseem ceeb, monomers yog lub tsev thaiv rau cov molecules, suav nrog cov proteins , starches thiab ntau lwm yam polymers. Muaj plaub lub ntsiab monomers: amino acids, nucleotides, monosaccharides thiab fatty acids. Cov monomers tsim cov hom yooj yim ntawm macromolecules: cov proteins , nucleic acids, carbohydrates thiab lipids.
Ib tug kuj yuav nug, ua li cas koj txheeb xyuas cov polymers thiab monomers?
Monomers yog ib tug neeg units uas tsim ib polymer . Peb ua tau txiav txim dab tsi monomer yog los ntawm thawj zaug nrhiav qhov tsawg tshaj plaws rov qab qauv. Peb ces yuav tsum tau txiav txim Yog hais tias tag nrho cov pa roj carbon atoms nyob rau hauv uas rov qab qauv muaj ib tug octet.
Puas yog dej monomer lossis polymer?
Cov cov monomers ua ke nrog ib leeg ntawm covalent bonds los tsim cov molecules loj dua hu ua polymers . Ua li ntawd, cov monomers tso tawm dej molecules ua byproducts.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Puas yog cov kab sib txuas ua pov thawj cov kab sib txuas?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, yog sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug
Dab tsi yog cov txheej txheem ntawm kev sib txuas monomers los tsim cov saw ntev?
Feem ntau cov roj ntsha molecules loj heev thiab tsim los ntawm kev sib sau me me molecules, los yog monomers, rau hauv cov saw ntev. Cov txheej txheem ntawm kev sib txuas cov monomers, hu ua lub cev qhuav dej condensation, suav nrog kev tshem tawm ob lub atoms hydrogen thiab ib qho oxygen atom los tsim dej
Dab tsi ntawm cov khoom sib txuas sib txuas muaj nyob ntawm cov dej molecules?
Piv txwv li, dej molecules yog tuav ua ke los ntawm hydrogen bonds ntawm hydrogen atom ntawm ib lub molecule thiab cov pa atom ntawm lwm tus (daim duab: hydrogen bonds). Hydrogen bonds yog ib qho muaj zog intermolecular quab yuam thiab muaj zog dua lwm cov dipole-dipole rog
