Y Protein vs Creatine
Amino acid yog ib qho yooj yim molecule tsim nrog C, H, O, N thiab tej zaum yuav yog S. Nws muaj cov qauv hauv qab no.
Muaj txog 20 hom amino acids. Tag nrho cov amino acids muaj -COOH, -NH2 pawg thiab -H sib txuas rau carbon. Cov pa roj carbon monoxide yog chiral carbon, thiab alpha amino acids yog qhov tseem ceeb tshaj plaws hauv lub ntiaj teb lom neeg. Cov pab pawg R sib txawv ntawm cov amino acid, rau amino acid. Qhov yooj yim amino acid nrog R pawg ua H yog glycine. Raws li cov pab pawg R, cov amino acids tuaj yeem muab faib ua aliphatic, aromatic, tsis muaj polar, polar, zoo them, tsis zoo, lossis polar uncharged, thiab lwm yam. Amino acids tam sim no raws li zwitter ions nyob rau hauv lub cev pH 7.4. Amino acids yog lub tsev blocks ntawm cov proteins, thiab lawv koom nyob rau hauv synthesizing lwm yam tseem ceeb molecules nyob rau hauv biological systems, thiab.
YProtein
Proteins yog ib hom tseem ceeb tshaj plaws ntawm macromolecules hauv cov kab mob nyob. Proteins tuaj yeem raug faib ua thawj, theem nrab, qib thib ob thiab quaternary proteins nyob ntawm lawv cov qauv. Qhov sib lawv liag ntawm cov amino acids (polypeptide) nyob rau hauv ib tug protein yog hu ua ib tug thawj qauv. Thaum muaj ntau cov amino acids koom ua ke, cov saw hlau hu ua polypeptide. Thaum cov txheej txheem polypeptide quav mus rau hauv kev sib koom ua ke, lawv paub tias yog cov proteins thib ob. Hauv cov txheej txheem tertiary, cov proteins muaj peb qhov qauv. Thaum ob peb seem protein moieties khi ua ke, lawv tsim cov quaternary proteins. Cov qauv peb sab ntawm cov protein nyob ntawm seb cov hydrogen bonds, disulfide bonds, ionic bonds, hydrophobic interactions, thiab tag nrho lwm yam kev sib cuam tshuam ntawm cov amino acids.
Proteins ua si ntau lub luag haujlwm hauv cov kab ke nyob. Lawv koom nrog kev tsim cov qauv. Piv txwv li, cov leeg muaj protein ntau fibers xws li collagen thiab elastin. Lawv kuj pom muaj nyob rau hauv cov txheej txheem nyuaj thiab nruj xws li cov rau tes, plaub hau, hooves, plaub, thiab lwm yam. Cov proteins ntxiv muaj nyob rau hauv cov ntaub so ntswg zoo li pob txha mos. Lwm yam tshaj li kev ua haujlwm, cov proteins muaj kev tiv thaiv ib yam nkaus.
Cov tshuaj tiv thaiv yog cov proteins, thiab lawv tiv thaiv peb lub cev los ntawm kev kis kab mob txawv teb chaws. Tag nrho cov enzymes yog cov proteins. Enzymes yog lub ntsiab molecules uas tswj tag nrho cov haujlwm metabolic. Tsis tas li ntawd, cov proteins koom nrog hauv cell signaling. Proteins yog tsim los ntawm ribosomes. Protein ua teeb liab raug xa mus rau ribosome los ntawm cov noob hauv DNA. Qhov xav tau cov amino acids tuaj yeem yog los ntawm kev noj zaub mov lossis tuaj yeem ua rau hauv lub cell.
Protein denaturation ua rau nthuav tawm thiab tsis sib haum xeeb ntawm cov proteins 'secondary thiab tertiary qauv. Qhov no tuaj yeem yog vim cua sov, cov kuab tshuaj organic, cov kua qaub thiab cov hauv paus, cov tshuaj detergents, mechanical force, thiab lwm yam.
YCreatine
Creatine yog ib qho chaw uas muaj nyob hauv cov pob txha. Nws yog nitrogenous compound thiab muaj ib pawg carboxylic rau nws, thiab. Creatine muaj cov qauv hauv qab no.
Thaum cais tawm nws muaj cov xim dawb crystalline zoo li. Nws tsis muaj ntxhiab, thiab cov molar loj yog li 131.13 g mol−1.
Creatine yog biosynthesized hauv peb lub cev los ntawm cov amino acids. Cov txheej txheem tsuas yog siv rau hauv daim siab thiab lub raum. Tom qab synthesizing, nws yog thauj mus rau cov leeg thiab khaws cia rau ntawd. Creatine nce qhov tsim ntawm ATP, yog li pab muab lub zog rau cov hlwb hauv lub cev.
Qhov txawv ntawm Protein thiab Creatine yog dab tsi?
• Protein yog macromolecule whereas creatine yog ib qho me me molecule.
• Protein muaj peptide bonds tab sis creatine tsis muaj peptide bonds.
• Proteins tuaj yeem sib xyaw ua ke hauv txhua lub cell nyob hauv qhov sib piv rau creatine.
