Cov protein raug suav hais tias yog polymers vim muaj tsim los ntawm polymerization ntawm cov amino acids thiab li no, amino acids yog monomers ntawm cov proteins thiab peptides. Hauv ib protein ntau molecule, amino acids yog tuav ua ke ntawm peptide bonds. Amino acids tseem hu ua 'tsev blocks' ntawm cov proteins.
Xav txog qhov no, vim li cas cov protein raug suav hais tias yog polymer?
Kev piav qhia: Cov protein yog tsim los ntawm ntau pua txawm txhiab tus amino acids khi ua ke los ntawm peptide bonds. Cov tshuaj tiv thaiv no tuaj yeem ua rau tsis muaj sijhawm los tsim cov saw ntev ntawm cov amino acids, Cov saw ntev ntawm cov amino acids hu ua polypeptide lossis protein ntau . Raws li ib tug protein ntau Qhov tseeb yog polypeptide, a protein ntau yog a polymer.
Tsis tas li ntawd, dab tsi polymers ua cov proteins? amino acids
Kuj Paub, yog cov proteins polymers?
Cov protein yog polymers ua los ntawm cov amino acids. Lawv tshwm sim ib txwm muaj, txhais tau tias lawv tau tsim los ntawm cov tsiaj, nroj tsuag, kab, fungi, thiab lwm yam muaj sia - thiab suav nrog koj! A protein ntau Qhov tseeb yog polyamide (ib yam dab tsi?), tab sis ntau ntxiv txog qhov ntawd tom qab. Yog li ntawd, cov proteins yog polymers ntawm cov amino acids.
Vim li cas cov proteins thiab carbohydrates yog polymers?
Polymers yog macromolecules ua los ntawm ob lossis ntau dua monomers. Piv txwv li, hmoov txhuv nplej siab yog a polymer . Nws yog ib txoj kab ntev ntawm cov piam thaj molecules. Cov protein yog polymers tsim los ntawm chains ntawm amino acids.

Yuav ua li cas cov hlwb tsim thiab tso cov proteins?
Thaum lub cell yuav tsum tau ua ib tug protein, mRNA yog tsim nyob rau hauv lub nucleus. Tom qab ntawd, mRNA raug xa tawm ntawm lub nucleus thiab mus rau ribosomes. Nrog rau mRNA muab cov lus qhia, ribosome txuas mus rau tRNA thiab rub tawm ib qho amino acid. Tom qab ntawd tRNA tso tawm rov qab rau hauv lub cell thiab txuas mus rau lwm cov amino acid
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
Vim li cas cov cell membrane yuav tsum tau thauj cov proteins?
Kev piav qhia: Lawv pab cov molecules thoob plaws hauv daim nyias nyias ntawm kev thauj mus los, ib txoj kev hu ua kom yooj yim diffusion. Cov proteins no yog lub luag haujlwm rau nqa ions thiab lwm cov molecules me rau hauv lub cell
Yuav ua li cas cov cell siv cov proteins quizlet?
Ib lub ribosome txuas rau mRNA hauv cytoplasm. Ntawm ribosome, mRNA muab cov cai rau cov protein uas yuav ua. Hauv cytoplasm, cov amino acids tshwj xeeb yog txuas rau cov molecules tshwj xeeb. Tom qab ntawd, tRNA txuas rau mRNA
Cov proteins ua haujlwm li cas los ua kom cov membranes xaiv permeable?
Cov lus teb yog cov protein. Proteins dot saum npoo ntawm bilayer, ntab zoo li rafts. Qee cov proteins no muaj cov kab, lossis qhov rooj ntawm lub xov tooj ntawm tes thiab ib puag ncig. Cov channel cia cov khoom loj dua uas yog hydrophilic thiab feem ntau tsis tuaj yeem dhau ntawm daim nyias nyias mus rau hauv lub cell
