Heme arginate (or haem arginate) is a compound of heme and arginine used in the treatment of acute porphyrias. [1] [2] This heme product is only available outside the United States and is equivalent to hematin. [3] Heme arginate is a heme compound, whereby L-arginine is added to prevent rapid degradation.
Intravenous hemin (as heme arginate or hematin) is the recommended therapy for acute attacks. [ 3 ] [ 7 ] Acute attacks can be severe enough to cause death if not treated quickly and correctly. Hospitalization is typically required for administration of hemin, and appropriate drug selection is key to avoid exacerbating symptoms with drugs that ...
Hemin is protoporphyrin IX containing a ferric iron (Fe 3+) ion with a coordinating chloride ligand.. Chemically, hemin differs from the related heme-compound hematin chiefly in that the coordinating ion is a chloride ion in hemin, whereas the coordinating ion is a hydroxide ion in hematin. [2]
Haematin (also known as hematin, ferriheme, hematosin, hydroxyhemin, oxyheme, phenodin, or oxyhemochromogen) is a dark bluish or brownish pigment containing iron in the ferric state, obtained by the oxidation of haem.
Heme D is the site for oxygen reduction to water of many types of bacteria at low oxygen tension. [24] Heme S is related to heme B by having a formyl group at position 2 in place of the 2-vinyl group. Heme S is found in the hemoglobin of a few species of marine worms.
Sierra Pacific Industries (SPI) is the second-largest lumber producer in the United States. [1] A privately held company, it was co-founded in 1949 by R. H. Emmerson and his son, A. A. "Red" Emmerson, the long-term CEO, and A. A. Emmerson's sons George and Mark are now president and CEO.
Heme A (or haem A) is a heme, a coordination complex consisting of a macrocyclic ligand called a porphyrin, chelating an iron atom. Heme A is a biomolecule and is produced naturally by many organisms. Heme A, often appears a dichroic green/red when in solution, is a structural relative of heme B, a component of hemoglobin, the red pigment in blood.
The number of heme C units bound to a holoprotein is highly variable. For vertebrate cells one heme C per protein is the rule but for bacteria this number is often 2, 4, 5, 6 or even 16 heme C groups per holoprotein. It is generally agreed the number and arrangement of heme C groups are related and even required for proper holoprotein function.
