Monomers yog ib tug neeg units uas tsim ib tug 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 tias tag nrho cov pa roj carbon atom hauv qhov kev rov ua dua tshiab muaj octet.

Tsis tas li ntawd, dab tsi yog monomer hauv chemistry?

Monomer , ib qho molecule ntawm ib chav kawm ntawm cov tebchaw, feem ntau yog cov organic, uas tuaj yeem hnov mob nrog lwm cov molecules los tsim cov molecules loj heev, lossis polymers. Qhov tseem ceeb feature ntawm a monomer yog polyfunctionality, muaj peev xwm tsim tshuaj daim ntawv cog lus rau yam tsawg kawg yog ob leeg monomer molecules.

Ib yam li ntawd, 4 hom monomers yog dab tsi? 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.

Qhov thib ob, cov piv txwv ntawm monomers yog dab tsi?

Glucose, vinyl chloride, amino acids, thiab ethylene yog piv txwv ntawm monomers . Txhua monomer tuaj yeem txuas rau ntau txoj hauv kev los tsim ntau yam polymers. Nyob rau hauv cov ntaub ntawv ntawm qabzib, rau piv txwv , glycosidic bonds tuaj yeem txuas cov suab thaj cov monomers los tsim cov polymers xws li glycogen, starch, thiab cellulose.

Dab tsi yog monomer ntawm carbohydrate hu ua thiab koj tuaj yeem txheeb xyuas tau li cas?

Carbohydrates yog ib qho ntawm plaub lub hauv paus cov macromolecules ntawm lub neej. Lawv yog cov polymer ua los ntawm monomers hu ua monosaccharides . Cov tsev thaiv no yog cov suab thaj yooj yim, piv txwv li, qabzib thiab fructose . Ob monosaccharides kev sib txuas ua ke ua rau lub disaccharide.
