Y Proteins yog heteropolymers
raws li lawv tau tsim los ntawm cov amino acids sib txawv . Lawv muaj peb-dimensional kev npaj. Lawv muaj cov amino acid, hydrogen, nitrogen thiab COOH pawg txuas rau nws.
Vim li cas cov proteins suav tias yog polymers?
Ntxiv rau carbon, hydrogen, thiab oxygen, amino acids muaj nitrogen. Proteins yog loj, intricate molecules ua los ntawm twisted thiab folded amino acid strands. … Yog li, cov proteins raug suav hais tias yog cov polymers vim Ib lub polymer yog tsim los ntawm ntau cov subunits interconnectedIb cov protein yog tsim los ntawm ntau cov amino acid subunits.
YPuas protein yog heteropolymer tsis homopolymer?
Yog tias tag nrho cov monomers zoo tib yam cov polymer yog homopolymer. Piv txwv li, cov hmoov txhuv nplej siab tsuas yog ua los ntawm cov piam thaj molecules yog li cov hmoov txhuv nplej siab yog homopolymer. Yog tias cov monomers tsis zoo ib yam, cov polymer yog heteropolymer. Proteins yog tsim los ntawm ntau txog 20 yam amino acids, yog li proteins yog heteropolymers
Lub ntsiab lus ntawm Heteropolymers yog dab tsi?
Nqe. (chemistry) Ib qho polymer muab tau los ntawm ob lossis ntau qhov sib txawv (tab sis feem ntau zoo sib xws) hom monomer.
YPuas yog proteins homopolymer ntawm amino acids?
Ib homopolymer tsuas muaj ib hom tsev thaiv hu ua monomer rov 'n' tus naj npawb ntawm zaus. Heteropolymer muaj ntau tshaj ib hom monomer. YProteins yog heteropolymer ua los ntawm cov amino acids.

Yuav ua li cas cov proteins tsim los ntawm cov amino acids?
Proteins yog tsim nyob rau hauv cov tshuaj tiv thaiv condensation thaum cov amino acid molecules koom ua ke thiab cov dej molecule raug tshem tawm. Daim ntawv cog lus tshiab tsim nyob rau hauv cov protein molecules uas cov amino acids tau koom nrog (-CONH) yog hu ua amide link lossis peptide link .
Yuav ua li cas hloov cov activator proteins?
Feem ntau cov activators ua haujlwm los ntawm binding sequence-tshwj xeeb rau lub chaw tswj hwm DNA nyob ze ntawm tus txhawb nqa thiab ua cov protein-protein cuam tshuam nrog cov tshuab luam ntawv dav dav (RNA polymerase thiab cov khoom siv dav dav.
Nyob hauv tus hu nkauj thiab nicolson qauv cov proteins extrinsic yog?
Cov proteins uas tawm sab nraud yog soluble thiab tuaj yeem nkag tau los ntawm daim nyias nyiasthiab lawv nyob sab nraud ntawm phospholipid bilayer. Nws yog xoob txuam nrog cov proteins hauv nruab nrab thiab tuaj yeem sib cais tau yooj yim.
Puas yog tag nrho cov proteins tsim hauv cytosol?
Proteins txhua tus pib lawv cov synthesis hauv cytosol … Qee qhov tau ua tiav tag nrho hauv cytosol. Cov no tuaj yeem raug xa mus rau hauv mitochondrion, peroxisome, chloroplast, thiab nucleus ntawm kev thauj mus los tom qab kev txhais lus. Lwm cov proteins yog co-translationally imported rau hauv endoplasmic reticulum .
Cov proteins ua nyob qhov twg?
Ribosomes yog qhov chaw uas cov proteins yog synthesis. Cov txheej txheem kev hloov pauv qhov twg cov lej ntawm DNA tau theej tshwm sim hauv cov nucleus tab sis cov txheej txheem tseem ceeb ntawm kev txhais cov lej ntawd los ua lwm cov protein tshwm sim hauv ribosomes .
