Tshuaj lom neeg polymers yog cov loj molecules tsim los ntawm ntau yam zoo sib xws me me molecules txuas ua ke nyob rau hauv ib tug chain-zoo li zam. Cov me me molecules yog hu ua monomers. Thaum me me cov organic molecules koom ua ke, lawv tuaj yeem tsim cov molecules loj lossis polymers.

Yog li ntawd, yog vim li cas lipids tsis yog ib tug tiag tiag polymer?

Proteins yog polymers ntawm cov molecules hu ua amino acids, qee qhov muaj ntau txhiab. Lipids yog tsim thaum glycerol molecule ua ke nrog cov tebchaw hu ua fatty acids, yog li lawv yog tsis yog polymers vim lawv muaj ib lub molecule thiab yog tsis yog cov macromolecules.

Tsis tas li ntawd, dab tsi yog lub ntsiab lus yooj yim polymer? A polymer yog ib qho molecule, ua los ntawm kev sib koom ua ke ntau lub me me molecules hu ua monomers. Lo lus " polymer "tuaj yeem tawg ua "poly" (lub ntsiab lus "ntau" hauv Greek) thiab "mer" (lub ntsiab lus "unit"). Proteins muaj polypeptide molecules, uas yog ntuj. polymers ua los ntawm ntau yam amino acid monomer units.

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

Piv txwv ntawm Polymers Ntuj polymers (tseem hu ua biopolymers) suav nrog silk, roj hmab, cellulose, wool, amber, keratin, collagen, starch, DNA, thiab shellac.

Dab tsi yog 4 hom polymers?

• Ntxiv Polymers.
• Polyethylene.
• Polypropylene.
• Poly (tetrafluoroethylene)
• Poly (vinyl Chloride) thiab Poly (vinylidene Chloride)
• Acrylics.
• Condensation Polymers.
