Muaj plaub yooj yim hom ntawm biomacroolecules: carbohydrates, lipids, proteins, thiab nucleic acids polymers muaj li ntawm txawv monomers thiab pab txawv muaj nuj nqi. Carbohydrates: molecules tsim los ntawm qab zib monomers. Lawv yog qhov tsim nyog rau kev khaws cia hluav taws xob.
Ib yam li ntawd ib tug yuav nug, dab tsi yog hom polymers?
Yim yam feem ntau ntawm cov hluavtaws organic polymers, uas feem ntau pom hauv tsev neeg yog:
- Tsawg-density polyethylene (LDPE)
- High-density polyethylene (HDPE)
- Polypropylene (PP)
- Polyvinyl chloride (pvc)
- Polystyrene (PS)
- Nylon, nylon 6, nylon 6, 6.
- Teflon (Polytetrafluoroethylene)
- Thermoplastic polyurethanes (TPU)
Ib yam li ntawd, qee qhov piv txwv ntawm polymers hauv biology yog dab tsi? Piv txwv ntawm ntuj polymers yog cellulose, shellac thiab amber. Biopolymers xws li cov proteins thiab nucleic acids ua lub luag haujlwm tseem ceeb hauv lom txheej txheem. Common synthetic polymers yog Bakelite, neoprene, nylon, PVC (polyvinyl chloride), polystyrene, polyacrylonitrile thiab PVB (polyvinyl butyral).
Hais txog qhov no, dab tsi yog 4 hom macromolecules thiab lawv txoj haujlwm?
Nyob ntawd yog plaub loj chav kawm ofbiological cov macromolecules (carbohydrates, lipids, proteins, thiab nucleic acids), thiab txhua yam yog ib qho tseem ceeb ntawm cov celland ua ib tug dav array ntawm muaj nuj nqi.
Dab tsi yog siv cov polymers?
Cov Kev siv cov polymers Polypropene muaj ntau yam kev siv hauv kev lag luam xws li ntawv sau, textiles, ntim, yas, dav hlau, kev tsim kho, hlua, khoom ua si, thiab lwm yam. Polystyrene yog ib qho ntawm cov yas feem ntau, uas nquag siv hauv kev ntim khoom.
