Macromolecules yog tsim los ntawm cov qauv molecular units. Lawv suav nrog cov proteins (polymer ntawm amino acids), nucleic acids (polymer ntawm nucleotides), carbohydrates (polymers ntawm qab zib) thiab lipids (nrog rau ntau yam modular constituents).

Yog li ntawd, cov qauv thiab kev ua haujlwm ntawm 4 macromolecules yog dab tsi?

Muaj plaub chav kawm loj ntawm biological macromolecules ( carbohydrates , lipids , cov proteins , thiab nucleic acids ); txhua tus yog ib qho tseem ceeb ntawm tes thiab ua haujlwm ntau yam. Ua ke, cov molecules no ua rau feem ntau ntawm cov cell qhuav qhuav (nco ntsoov tias cov dej ua rau feem ntau ntawm nws cov khoom tiav).

Ib yam li ntawd, cov qauv ntawm macromolecule cuam tshuam nws txoj haujlwm li cas? Cov ua haujlwm pawg txiav txim cov duab ntawm cov macromolecules thiab qhov no nyob rau hauv lem txiav txim lawv lub luag haujlwm . Proteins muaj complex cov qauv tshwm sim los ntawm kev sib cuam tshuam ntawm cov ua haujlwm pab pawg. Ib qho kev hloov pauv ntawm ib qho amino acid tuaj yeem ua rau muaj kev hloov pauv loj muaj nuj nqi ntawm ib qho protein.

Ib yam li ntawd, qhov sib txawv muaj nyob hauv cov qauv ntawm macromolecules?

Proteins, carbohydrates, nucleic acids, thiab lipids yog plaub chav kawm loj ntawm kev lom neeg cov macromolecules -loj molecules tsim nyog rau lub neej uas yog tsim los ntawm me me organic molecules. Macromolecules yog tsim los ntawm ib chav tsev hu ua monomers uas tau koom nrog covalent bonds los tsim cov polymers loj.

Cov haujlwm ntawm biomolecules yog dab tsi?

Biomolecules muaj ntau yam loj heev muaj nuj nqi , xws li khaws cia lub zog, kev tiv thaiv, thiab lwm yam. Thaum peb tham txog biomolecules , feem ntau muaj 4 hom tseem ceeb ntawm lawv: proteins, lipids, carbohydrates thiab nuclei acids.
