Monomers yog me me molecules uas tej zaum yuav koom ua ke nyob rau hauv ib tug rov ua qauv ua form complex molecules hu ua polymers . Monomers tsim cov polymers los ntawm kev tsim cov tshuaj bonds los yog khi supramolecularly los ntawm cov txheej txheem hu ua polymerization.
Tsuas yog li ntawd, ua li cas cov polymers ua monomers?
Lub cev qhuav dej Synthesis Feem ntau macromolecules yog tsim los ntawm ib lub subunits, los yog lub tsev blocks, hu ua cov monomers . 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 dej molecules ua byproducts. Nyob rau hauv tus txheej txheem, ib tug dej molecule yog tsim.
Tom qab ntawd, lo lus nug yog, dab tsi yog monomers thiab polymers? Polymer txhais tau tias ntau cov monomers . Qee zaum polymers tseem hu ua macromolecules lossis loj-loj molecules. Feem ntau, polymers yog cov organic (tab sis tsis tas). A monomer yog ib qho molecule uas muaj peev xwm sib txuas hauv cov saw ntev. Qhov no sib txuas ntawm cov monomers hu ua polymerization.
Nyob rau hauv no txoj kev, yuav ua li cas yog polymers?
Polymer Tsim. Polymers yog tsim los ntawm ob txoj kev tseem ceeb hu ua ntxiv thiab condensation polymerization. Tsis tas li ntawd, polymerization, tus pib (los yog catalyst) reacts nrog ib tug pib monomer. Daim ntawv cog lus tsis txaus siab yog pub dawb los teb nrog lwm tus monomer, yog li ntxiv rau cov saw hlau.
Puas yog lipids monomers lossis polymers?
Glycerol thiab fatty acids yog cov cov monomers uas ua lipids . Nucleotides yog cov cov monomers uas tsim cov nucleic acids. Amino acids yog cov cov monomers uas ua rau cov protein. Sequences ntawm cov monomers koom ua ke ua polymers.

Cov monomers thiab polymers sib txuas li cas?
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 cov polymers. Tag nrho cov monomers muaj peev xwm tsim cov tshuaj tiv thaiv rau tsawg kawg yog ob lub monomer molecules. Polymers yog chains nrog ib tug unspecified tooj ntawm monomeric units
Dab tsi lom macromolecule yog tsim los ntawm monomers?
Muaj plaub hom kev lom macromolecules: carbohydrates, lipids, proteins, thiab nucleic acids. Cov polymers no yog tsim los ntawm cov monomers sib txawv thiab ua haujlwm sib txawv. Carbohydrates: molecules tsim los ntawm qab zib monomers. Lawv tsim nyog rau lub zog cia
Vim li cas cov proteins polymers?
Cov proteins raug suav tias yog cov polymers vim tias muaj cov polymerization ntawm cov amino acids thiab yog li, cov amino acids yog monomers ntawm cov proteins thiab peptides. Hauv cov protein molecule, amino acids tau tuav ua ke ntawm peptide bonds. Amino acids tseem hu ua 'tsev blocks' ntawm cov proteins
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
Yuav ua li cas polymers tsim?
Thaum ntau cov molecules ntawm ib qho yooj yim compound koom ua ke, cov khoom yog hu ua ib tug polymer thiab cov txheej txheem polymerization. Cov tebchaw yooj yim uas nws cov molecules koom ua ke los tsim cov polymers hu ua monomers. Lub polymer yog cov saw hlau ntawm cov atoms, muab cov pob txha, uas cov atoms lossis pawg ntawm cov atoms koom nrog
