Qhov sib txawv tseem ceeb ntawm ribitol thiab glycerol teichoic acid yog ribitol teichoic acid muaj polyribitol phosphate units hauv cov saw tseem ceeb, thaum glycerol teichoic acid muaj poly-glycerol phosphate units hauv cov saw tseem ceeb.
Teichoic acid yog ib qho chaw muaj nyob rau hauv lub cell phab ntsa ntawm feem ntau Gram-zoo kab mob. Teichoic acids yog copolymer ntawm glycerol phosphate los yog ribitol phosphate thiab carbohydrates. Lawv txuas ua ke los ntawm phosphodiester bonds. Lub luag haujlwm tseem ceeb ntawm teichoic acid nyob rau hauv cov kab mob yog muab kev yooj yim rau phab ntsa ntawm tes los ntawm kev nyiam cov cations. Muaj ob hom teichoic acids nyob rau hauv lub cell phab ntsa. Lawv yog cov phab ntsa teichoic acid thiab lipoteichoic acids. Phab ntsa teichoic acids txuas nrog peptidoglycan thaum lipoteichoic acids txuas rau daim nyias nyias lipids. Teichoic acids ua rau lawv muaj peev xwm tshuaj tua kab mob hom phiaj. Raws li cov polyol phosphate nyob rau hauv cov saw tseem ceeb ntawm teichoic acid, muaj ob hom teichoic acids li ribitol thiab glycerol teichoic acid.
Ribitol Teichoic Acid yog dab tsi?
Ribitol teichoic acid yog ib hom teichoic acid uas muaj polyribitol phosphate saw. Qhov rov ua dua yog ribitol-1-phosphate. Poly ribitol txuas nrog phosphodiester txuas hniav. Hauv ntau cov kab mob gram-zoo, subtype I-R 1, 5 polymers (phosphodiester bonds txuas C-1 thiab C-5 ntawm ribitol) yog qhov feem ntau pom. Thaum piv rau glycerol teichoic acid, ribitol teichoic acid tsis tshua muaj tshwm sim hauv cell phab ntsa teichoic acids.
Daim duab 01: Lipoteichoic Acid
YGlycerol Teichoic Acid yog dab tsi?
Glycerol teichoic acid yog ib hom teichoic acid uas muaj poly-glycerol phosphate saw. Qhov rov ua dua yog glycerol-1-phosphate. Muaj kwv yees li 20 mus rau 30 rov ua dua hauv cov saw hlau polyglycerol phosphate.
Daim duab 02: Glycerol-1-phosphate
Polyglycerol units yog txuas los ntawm phosphodiester txuas hniav. 1, 3-poly (glycerol phosphate) thiab 2, 3-poly (glycerol phosphate) polymers yog ob hom uas sawv cev rau polyglycerol phosphates. Poly-glycerol phosphates yog cov kab mob loj tshaj plaws ntawm cov phab ntsa ntawm tes teichoic acids.
Dab tsi yog qhov zoo sib xws ntawm Ribitol thiab Glycerol Teichoic Acid?
- Ob leeg ribitol thiab glycerol teichoic acid yog ob hom teichoic acid raws li cov saw hlau polyol.
- Lawv tsuas pom muaj nyob rau hauv cov kab mob gram-zoo kab mob cell phab ntsa.
- Cov glycerol phosphate lossis ribitol phosphate yog txuas ntawm phosphodiester bonds.
- Ob hom tuaj yeem txheeb xyuas raws li qhov hloov pauv ntawm cov polyols thiab thaj chaw ntawm phosphodiester bonds.
Qhov txawv ntawm Ribitol thiab Glycerol Teichoic Acid yog dab tsi?
Ribitol teichoic acid muaj cov saw poly-ribitol phosphate thaum glycerol teichoic acid muaj cov saw poly-glycerol phosphate. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm ribitol thiab glycerol teichoic acid. Ntxiv mus, lwm qhov sib txawv ntawm ribitol thiab glycerol teichoic acid yog piv rau ribitol teichoic acid, glycerol teichoic acid tshwm sim ntau dua nyob rau hauv cov kab mob cell phab ntsa teichoic acids.
Summary – Ribitol vs Glycerol Teichoic Acid
Teichoid acid yog ib qho tshwj xeeb polymer pom nyob rau hauv Gram-zoo kab mob cell phab ntsa. Muaj ob hom teichoic acids: phab ntsa teichoic acid (txuas mus rau peptidoglycan) thiab lipoteichoic acid (txuas nrog cytoplasmic membrane). Teichoic acid yog ib qho polymer ntawm glycerol lossis ribitol. Raws li qhov ntawd, muaj ob hom teichoic acids li ribitol teichoic acid thiab glycerol teichoic acid. Ribitol teichoic acid muaj cov saw ntev uas muaj ribitol phosphate rov ua dua thaum glycerol teichoic acid muaj cov saw ntev ntawm glycerol phosphate rov ua dua. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm ribitol thiab glycerol teichoic acid.
