Peptidoglycan (murein) yog ib qho polymer uas muaj suab thaj thiab cov amino acids uas tsim ib txheej zoo li mesh sab nraum cov plasma daim nyias nyias ntawm cov kab mob feem ntau, tsim cov kab mob mesh. cell phab ntsa . Cov khoom noj qab zib muaj cov alternating residues ntawm β-(1, 4) txuas N-acetylglucosamine (NAG) thiab N-acetylmuramic acid (NAM).

Cov lus nug tseem yog, dab tsi yog peptidoglycan synthesis?

Lub biosynthesis ntawm cov kab mob cell phab ntsa peptidoglycan yog ib qho txheej txheem nyuaj uas cuam tshuam nrog cov tshuaj tiv thaiv enzyme uas tshwm sim hauv cytoplasm ( synthesis ntawm nucleotide precursors) thiab sab hauv ( synthesis ntawm lipid-txuas intermediates) thiab sab nraud (polymerization cov tshuaj tiv thaiv) ntawm cytoplasmic membrane.

Ib yam li ntawd, qhov muaj pes tsawg leeg ntawm peptidoglycan quizlet yog dab tsi? Peptidoglycan yog ib lub polymer ntawm ntau lab ntawm N-acetylglucosamine (NAG) thiab N-acetylmuramic acid (NAM) suab thaj raws li cov piam thaj molecules txuas ua ke hauv cov saw ntev cross-braced nrog plaub cov amino acids uas txuas ib tus neeg polymer chains ua ke nyob rau hauv ib tug chain-link laj kab qauv..

Ua kom pom qhov no, txheej txheej peptidoglycan ua li cas?

Lub cell phab ntsa muaj ib txheej ntawm peptidoglycan , ib qho molecule ib txwm pom tsuas yog hauv cov kab mob. Cov peptidoglycan txheej ua raws li lub cell phab ntsa, muab lub zog rau lub cell phab ntsa. Cov peptidoglycan txheej yog muaj peev xwm tso cov suab thaj, amino acids, thiab lwm yam ions mus rau hauv lub cell raws li xav tau.

Puas yog peptidoglycan yog Heteropolysaccharide?

Cov txheej txheem ntawm cov kab mob hauv lub hnab ntawv (the peptidoglycan ) yog a heteropolysaccharide ua los ntawm ob chav hloov monosaccharide.
