Vim qhov muaj ntau ntawm glycine thiab cov ntsiab lus proline, collagen tsis tuaj yeem tsim cov α-helix thiab β-daim qauv. Peb sab laug-tes helical strands twist los tsim ib txoj cai-tes triple helix. Ib qho collagen triple helix muaj 3.3 residues ib zaug.
YPuas collagen ua los ntawm alpha helix?
Collagen tseem yog tsim los ntawm coiled alpha-helicesthiab pom muaj nyob hauv daim tawv nqaij, pob txha pob txha thiab cov hniav. Tsis zoo li DNA ob chav stranded helices, cov protien alpha-helix yog tsim los ntawm tsuas yog ib tug strand ntawm polypeptides thiab yog ib tug ntau me dua DNA ob helix. alpha-helix yog ib qho piv txwv ntawm cov qauv protein thib ob.
YPuas yog collagen ua los ntawm helices?
Collagen yog cov protein ntau tshaj plaws hauv cov tsiaj. Qhov no fibrous, cov qauv protein muaj xws litxoj cai-tes pob ntawm peb qhov sib luag, sab laug tes polyproline II-hom helicesNtau qhov kev vam meej tau ua tiav hauv elucidating cov qauv ntawm collagen triple helices thiab lub hauv paus physicochemical. rau lawv stability.
YPuas collagen muaj peb alpha helices?
Cov Qauv Txheej Txheem Txheej Txheem ntawm Collagen Yog Triple Helix
Nws cov qauv tsim qauv yog qhov ntev (300-nm), nyias (1.5-nm-inch) protein uas muaj peb coiled subunits: ob α1(I) chains thiab ib α2(I).
collagen muaj li cas ?
Collagen yog cov protein ua los ntawm amino-acids, uas yog ua los ntawm carbon, oxygen thiab hydrogen. Collagen muaj cov amino acids tshwj xeeb - Glycine, Proline, Hydroxyproline thiab Arginine. Collagen tsim txog li 30% ntawm cov proteins hauv lub cev.
