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.
