Qhov sib txawv tseem ceeb ntawm porphyrin thiab protoporphyrin yog porphyrin yog ib pawg tshuaj tsw qab uas muaj plaub qhov hloov pauv pyrrole subunits interconnected rau ib leeg, whereas protoporphyrin yog ib tug derivative ntawm porphyrin uas muaj propionic acid pawg.
Ob leeg porphyrin thiab protoporphyrin yog cov tshuaj lom neeg muaj xim sib sib zog nqus. Cov no yog macrocyclic organic tebchaw uas muaj ntau lub voj voog ntawm cov pa roj carbon monoxide sib txuas ua ke ua ib qho loj molecule.
Porphyrin yog dab tsi?
Porphyrin yog cov organic loj uas muaj plaub qhov hloov pauv pyrrole subunits interconnected rau ib leeg. Cov qauv nplhaib no txuas rau ib leeg ntawm methine txuas hniav ntawm alpha carbon atoms. Tus choj methine muaj cov tshuaj formula –CH=. Niam txiv molecule ntawm porphyrin yog porphine. Nws yog hom tshuaj lom neeg tsawg. Porphyrins tsim los ntawm kev hloov pauv ntawm porphine.
Daim duab 01: Qhov tshwm sim thiab cov qauv ntawm Porphyrin
Porphyrins muaj cov qauv qauv uas yog lub voj voog txuas ntxiv, thiab peb tuaj yeem txhais tau tias nws muaj ntxhiab. Nws yog ib qho conjugated system uas muaj alternating pi bonds thiab ib daim ntawv cog lus. Cov tshuaj no yog cov xim sib sib zog nqus vim tias lawv tuaj yeem nqus tau cov wavelengths ntawm cov hluav taws xob hluav taws xob hauv qhov pom ntau yam; Piv txwv li, heme, uas muaj xim liab sib sib zog nqus, yog lub npe hu ua porphyrin uas tshwm sim ib txwm muaj.
Ntxiv mus, porphyrins tuaj yeem ua raws li kev sib txuas ntawm cov kua qaub ligands uas khi nrog cov hlau ions los tsim cov complexes. Ntawm no, cov hlau ion yog +2 lossis +3 them. Txawm li cas los xij, yog tias porphyrin tshwm sim tsis muaj hlau ion, peb hais tias lub hauv paus ntawm porphyrin yog khoob, thiab nws yog lub hauv paus dawb. Cov hlau uas muaj porphyrins muaj npe hu ua heme.
Sib nrug ntawm qhov ntawd, yog tias peb xav txog keeb kwm ntawm porphyrin, geologically nws tsim los ntawm protoporphyrin. Cov khoom sib txuas no tuaj yeem tshwm sim hauv cov roj av, roj shale, thee, sedimentary pob zeb, thiab lwm yam. Tsis tas li ntawd, peb tuaj yeem tsim cov molecules no. Cov synthesis tuaj yeem tshwm sim hauv cov txheej txheem lom neeg thiab. Ntawm no, tshwj xeeb eukaryotic hom xws li kab, tsiaj txhu, fungi, thiab lwm yam tuaj yeem biosynthesize porphyrins.
Protoporphyrin yog dab tsi?
Protoporphyrin yog ib qho derivative ntawm porphyrin. Nws yog ib qho organic compound uas muaj cov qauv nyuaj. Nws muaj xim sib sib zog nqus vim qhov nqus ntawm hluav taws xob hluav taws xob hauv qhov pom ntau yam. Ntxiv mus, cov tebchaw no tsis soluble hauv dej alkali. Nws yog ib qho tseem ceeb rau cov kab mob uas muaj sia nyob raws li qhov ua ntej rau cov tshuaj xws li hemoglobin, chlorophyll, thiab lwm yam.
Protoporphyrin muaj porphyrin core, thiab yog li ntawd, nws yog aromatic. Nws muaj cov qauv geometry tshwj tsis yog rau qhov khoov N-H daim ntawv cog lus. Tsis tas li ntawd, qhov sib xyaw no yog muab los ntawm porphyrin los ntawm kev hloov pauv ntawm sab nraud hydrogen atom hauv pyrrole rings nrog plaub pawg methyl, ob pawg vinyl thiab ob pawg propionic acid. Tsis tas li ntawd, qhov sib xyaw no muaj nyob hauv qhov xwm txheej; peb kuj tuaj yeem ua ke nws.
Qhov txawv ntawm Porphyrin thiab Protoporphyrin yog dab tsi?
Protoporphyrin yog ib qho derivative ntawm porphyrin. Qhov sib txawv tseem ceeb ntawm porphyrin thiab protoporphyrin yog tias porphyrin yog ib pawg tshuaj tsw qab uas muaj plaub qhov hloov pauv pyrrole subunits interconnected rau ib leeg, whereas protoporphyrin yog ib tug derivative ntawm porphyrin uas muaj propionic acid pawg.
Hauv qab infographic tabulates qhov txawv ntawm porphyrin thiab protoporphyrin.
Summary – Porphyrin vs Protoporphyrin
Protoporphyrin yog ib qho derivative ntawm porphyrin. Qhov sib txawv tseem ceeb ntawm porphyrin thiab protoporphyrin yog tias porphyrin yog ib pawg ntawm cov tshuaj tsw qab uas muaj plaub qhov hloov pauv pyrrole subunits interconnected rau ib leeg, whereas protoporphyrin yog ib tug derivative ntawm porphyrin uas muaj propionic acid pawg.
