Lysozyme muaj peev xwm tawg cov tshuaj tiv thaiv kab mob hauv cov phab ntsa sab nraud ntawm cov kab mobCov kab mob ntawm tes muaj ib txheej ntawm peptidoglycan, uas yog qhov chaw tshwj xeeb uas lysozyme lub hom phiaj. Cov txheej peptidoglycan muaj alternating molecules hu ua N-acetylglucosamine thiab N-acetylmuramic acid.
Lysozymes zom dab tsi?
Lysozyme, enzyme pom nyob rau hauv cov kua muag (lub kua muag) ntawm cov qog lacrimal ntawm cov tsiaj thiab hauv cov hnoos qeev, plab hnyuv, thiab qe dawb. Pom tau nyob rau xyoo 1921 los ntawm Sir Alexander Fleming, lysozyme catalyzes qhov kev tawg ntawm qee cov carbohydrates pom nyob rau hauv cov phab ntsa ntawm tes ntawm qee cov kab mob(xws li, cocci).
Lub luag haujlwm ntawm lysozyme yog dab tsi?
Lysozyme yog ib qho enzyme uas tshwm sim nyob rau hauv lub cev secretions xws li kua muag, qaub ncaug, thiab mis nyuj. Nws ua haujlwm raws li tus tshuaj tua kab mob los ntawm kev tshem cov peptidoglycan tivthaiv ntawm cov kab mob ntawm cov phab ntsa, uas ua rau kev tuag ntawm tes. … Ib yam li ntawd, lysozyme, ua ib qho khoom noj ntxiv, ua rau kev loj hlob thiab kev noj zaub mov zoo.
Yuav ua li cas daim ntawv cog lus lysozyme tawg?
Lysozyme pom dav hauv cov hlwb thiab cov zais zis (xws li kua muag thiab qaub ncaug) ntawm cov vertebrates, thiab qe qe dawb tshwj xeeb yog nplua nuj nyob rau hauv cov enzyme no. Lysozyme catalyses cov hydrolysis ntawm glycosidic bonds uas txuas N-acetylmuramic acid (NAM) thiab N-acetylglucosamine (NAG) hauv polysaccharides ntawm cov phab ntsa ntawm cov kab mob.
Dab tsi tuaj yeem ua rau lysozyme degrade?
Lysozyme degrades peptidoglycan nyob rau hauv cov kab mob cell phab ntsa ua rau sai tua cov kab mob Gram-zoo; Txawm li cas los xij, qhov txheej txheem no tsis tuaj yeem suav txog qhov kev tiv thaiv ntawm lysozyme tiv thaiv kab mob Gram-negative.
