Qhov tseem ceeb cov qauv ntawm lysozyme yog ib qho polypeptide uas muaj 129 amino acids. Hauv cov xwm txheej physiological, lysozyme yog folded rau hauv ib qho compact, globular qauv nrog ib tug ntev cleft nyob rau hauv cov protein nto.

Tom qab ntawd, ib tus tuaj yeem nug, lysozyme yog dab tsi thiab nws txoj haujlwm?

Lysozyme yog ib qho tshwj xeeb enzyme pom nyob rau hauv kua muag, qaub ncaug, hws, thiab lwm yam dej hauv lub cev. Lwm yam mucosal linings, xws li tus qhov ntswg kab noj hniav, kuj muaj lysozyme . Nws rhuav tshem cov kab mob uas sim nkag mus rau peb lub cev los ntawm cov kab no. Hauv tus cov kua muag, lawv tiv thaiv peb ob lub qhov muag los ntawm cov kab mob invaders.

lysozyme yog dab tsi? Lysozyme , enzyme pom nyob rau hauv cov kua muag (lub kua muag) ntawm cov qog lacrimal ntawm cov tsiaj thiab nyob rau hauv qhov ntswg mucus, gastric secretions, thiab qe dawb. Tshawb nrhiav hauv 1921 los ntawm Sir Alexander Fleming, lysozyme catalyzes qhov kev puas tsuaj ntawm qee cov carbohydrates pom hauv cov phab ntsa ntawm tes ntawm qee cov kab mob (xws li, cocci).

Ua li no, lysozyme puas muaj cov qauv quaternary?

Hydrogen tsis qhia. b) Piav qhov quaternary qauv ntawm lysozyme (Hint: Siv lub pob "Color Ribbon los ntawm Protein Subunit"). Muaj tsuas yog ib qho amino acid saw, yog li tsis muaj quaternary kev sib tham. Cov ribbon qauv yooj yim qhia ib kab ntawm cov pob txha polypeptide yam tsis tau qhia txog cov amino acid sab saw atoms.

Vim li cas cov qauv protein ntawm lysozyme tseem ceeb?

Yog li ntawd, lysozymes ua raws li ib feem ntawm lub cev tiv thaiv kab mob. High concentrations ntawm lysozymes kuj tuaj yeem pom hauv qe dawb. Lawv lub peev xwm los rhuav tshem cov kab mob hauv cov phab ntsa kom txhim kho protein ntau thiab nucleic extraction efficiency ua lysozymes tseem ceeb proteins nyob rau hauv cov tsiaj muaj sia.
