Porphyrins yog qhov tseem ceeb rau kev ua haujlwm ntawm hemoglobin - protein ntau hauv koj cov qe ntshav liab uas txuas mus rau porphyrin, khi hlau, thiab nqa oxygen rau koj lub cev thiab cov ntaub so ntswg. Cov qib siab ntawm porphyrins tuaj yeem ua rau muaj teeb meem loj.
Porphyrins siv rau dab tsi?
Porphyrins yog cov tshuaj uas pab ua hemoglobin, hom protein hauv koj cov qe ntshav liab. Hemoglobin nqa oxygen los ntawm koj lub ntsws mus rau tag nrho koj lub cev. Nws yog ib txwm muaj me me ntawm porphyrins hauv koj cov ntshav thiab lwm yam kua hauv lub cev.
porphyrin pom nyob qhov twg?
Porphyrins yog ubiquitous nyob rau hauv biological systems. Lawv yog cov chaw ua haujlwm hauv hemoglobin thiab chlorophyll. Lawv kuj yog ib feem ntawm cytochrome P-450 enzyme systems uas tsis tsuas yog tam sim no nyob rau hauv lub siabntawm cov kab mob siab dua tab sis kuj nyob rau hauv cov kab mob microbial.
Lub luag haujlwm ntawm porphyrin hauv chlorophyll yog dab tsi?
Chlorophyll yog cov xim ntsuab hauv cov nroj tsuag, algae, thiab cyanobacteria uas yog qhov tseem ceeb rau photosynthesis. … Nws lub hauv paus qauv yog ib qho aromatic porphyrin los yog chlorin (txo porphyrin) lub nplhaib system nrog ib tug sequestered magnesium atom. Lub nplhaib thib tsib yog fused rau porphyrin.
Porphyrin yog dab tsi?
Structurally, porphyrin muaj plaub pyrrole rings (tsib tus tswv cuab kaw cov qauv uas muaj ib qho nitrogen thiab plaub carbon atoms) txuas rau ib leeg los ntawm methine pawg(-CH=). Cov hlau atom yog khaws cia rau hauv nruab nrab ntawm lub nplhaib porphyrin los ntawm kev cuam tshuam nrog plaub nitrogen atoms.
