N-Acetyl Glucosamine yog dab tsi?
N-acetyl glucosamine yog ib qho amide uas tau los ntawm monosaccharide qabzib. Peb tuaj yeem hu nws ua ib qho amide thib ob tsim los ntawm glucosamine thiab acetic acid. Cov tshuaj no yog ib qho tseem ceeb rau ntau yam kab mob lom. Cov tshuaj formula ntawm no compound yog C8H15NO6.
Daim duab 1: Cov Qauv Tshuaj ntawm N-acetyl Glucosamine
N-acetyl glucosamine tuaj yeem pom raws li biopolymer hauv cov kab mob cell phab ntsa. Peb tuaj yeem yooj yim sau lub npe ntawm cov khoom no ua GlcNAc. Nws yog lub tsev monomeric ntawm polymer chitin. Chitin tsim cov exoskeleton ntawm anthropods xws li kab thiab crustaceans. Chitin yog qhov tseem ceeb ntawm radulas ntawm mollusks, beaks ntawm cephalopods, thiab nws yog ib qho tseem ceeb ntawm lub cell phab ntsa ntawm feem ntau fungi. Ntxiv mus, raws li polymerization ntawm N-acetyl glucosamine nrog glucuronic acid, nws tuaj yeem tsim hyaluronan.
Tsis tas li ntawd, N-acetyl glucosamine yog suav tias yog ib qho inhibitor ntawm elastase uas tau tso tawm los ntawm tib neeg polymorphonuclear leukocytes. Tab sis qhov no tsis muaj zog tshaj qhov inhibition uas tuaj yeem pom hauv N-acetylgalactosamine.
Thaum xav txog kev siv tshuaj kho mob ntawm N-acetyl glucosamine, nws muaj txiaj ntsig zoo li kev kho mob rau cov kab mob autoimmune; Qee qhov kev tshawb fawb tsis ntev los no tau pom tias qhov kev siv no tau ua tiav.
Qhov sib ntxiv ntawm N-acetyl glucosamine rau serine lossis threonine ntawm cov protein yog hu ua O-GlcNAcylation. Qhov no tshwm sim los ntawm kev ua kom los yog deactivating enzymes los yog transcription yam.
