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.
Amino acids tau hloov mus ua cov protein nyob qhov twg?
Txhua cov amino acid raug xa mus rau the ribosome los ntawm kev hloov RNA? molecule nyob ntawm tus lej hauv tus xa xov RNA. Cov amino acids no tau ntxiv rau hauv ib ntu los tsim cov saw ntawm cov amino acids. Tom qab qhov kawg amino acid ntxiv rau cov saw, nws folds mus rau tsim cov proteins kawg.
YYuav ua li cas proteins?
Proteins yog qhov tseem ceeb ua haujlwm molecules thiab tsim thaiv hauv txhua lub hlwb. Lawv raug tsim nyob rau hauv ib tug zoo xws li cov txheej txheem ob-kauj ruam nyob rau hauv tag nrho cov kab mob - DNA yog thawj transcribed rau RNA, ces RNA yog txhais ua protein.
Cov zaub mov twg yog cov proteins pom hauv?
YProtein zaub mov
- lean meats - nqaij nyug, yaj, nqaij nyug, nqaij npuas, kangaroo.
- qaib - qaib, qaib ntxhw, duck, emu, goose, bush noog.
- ntses thiab nqaij nruab deg – ntses, prawn, crab, lobster, mussels, oysters, scallops, clams.
- egg.
- khoom noj mis - mis nyuj, yogurt (tshwj xeeb yog Greek yogurt), cheese (tshwj xeeb yog tsev cheese)
pom cov protein nyob qhov twg?
Protein pom thoob plaws hauv lub cev-hauv cov leeg nqaij, pob txha, tawv nqaij, plaub hau, thiab txhua yam ntawm lub cev lossis cov ntaub so ntswg. Nws ua rau cov enzymes uas muaj zog ntau cov tshuaj tiv thaiv thiab hemoglobin uas nqa oxygen hauv koj cov ntshav. Yam tsawg kawg 10,000 proteins sib txawv ua rau koj zoo li cas thiab ua rau koj li ntawd.

Vim li cas cov amino acids chiral?
Txhua cov amino acids tshwj tsis yog glycine yog chiral vim tias lawv txhua tus muaj tsawg kawg ib lub chaw chiral Lub hauv paus carbon muaj plaub pawg sib txawv txuas. Yog li lub compound tuaj yeem muaj nyob ua ib khub ntawm daim iav uas tsis yog superimposable.
Kev tsim cov amino acids uas tsis tseem ceeb?
No tseem ceeb amino acids yog tsim los ntawm qabzib (alanine, arginine [los ntawm urea voj voog nyob rau hauv lub hlwb], asparagine, aspartate, cysteine, glutamate, glutamine, glycine, proline, thiab serine), tshwj tsis yog rautyrosine , uas yog tsim los ntawm phenylalanine .
Vim li cas kev thauj mus los tsim nyog rau kev nqus cov amino acids?
Vim tias lub cell plasma membrane yog tsim los ntawm hydrophobic phospholipids, dej-soluble as-ham yuav tsum siv thauj cov molecules embedded nyob rau hauv daim nyias nyias mus rau hauv lub hlwb. … Kev nqus ntawm cov as-ham feem ntau los ntawm cov mucosa ntawm txoj hnyuv villi yuav tsum muaj kev thauj mus los ntawm ATP Vim li cas cov amino acids xav tau kev thauj mus los?
Puas yog cov concentrated acids muaj zog acids?
A cov kua qaub uas muaj zog yog ib qho kev sib cais tag nrho los tsim H3O + ions hauv cov tshuaj aqueous, qhov twg raws li cov kua qaub tsis muaj zog tsuas yog ua qee yam. Cov kua qaub concentrated, ntawm qhov tod tes, yog ib qho uas muaj qhov siab heev ntawm H3O + ions hauv cov kua dej .
Ntawm physiological ph amino acids yog?
Rau cov amino acids no, cov ntawv protonated predominate ntawm lub cev pH ( kwv yees 7). Ob lub amino acids muaj acidic sab chains ntawm nruab nrab pH . Cov amino acids twg yog deprotonated ntawm physiological pH? Feem ntau ntawm cov no muaj nruab nrab sab chains.
