This Concept Map, created with IHMC CmapTools, has information related to: 08a. Heme Synthesis, Aminolevulinic acid (ALA) enzyme ALA Synthase, Aminolevulinic acid (ALA) second step formation of porphobilinogen (PBG), protoporphyrinogen IX Combines with Iron, Regulation inhibited by Hemin (Fe3+), Groups attached to pyrrole rings variations from normal have Different solubilities, Swich in group order some more intermediates then protoporphyrinogen IX, Bridge closure can be Enzymatic, Saturated Porphyrins, Ferroprotoprophyrin IX a type of Porphyrins, unusable form note A little of this occurs in all of us, 4 Bridge carbons are Saturated, protoporphyrinogen IX has 2 each of Methyl (M), Unsaturated Porphyrnogens, Groups attached to pyrrole rings can be Propionic Acid (P), Groups attached to pyrrole rings can be Vinyl (V), Hemin (Fe3+) May actually stimulate erythroid heme formation, 4 Bridge carbons are Unsaturated, Regulation induced by Naturally ocurring steroids, Unsaturated Become oxidized, ie, Saturated, Spontaneous makes unusable form
