According to the website, www.ducksters.com, “enzymes are special types of proteins. Like all proteins, enzymes are made from strings of amino acids. The function of the enzyme is determined by the sequence of amino acids, types of amino acids, and the shape of the string.” Along with this we need to…

    Special delivery of toxic cell-free heme causes vascular damage in Sickle Cell Disease Scientists describe a novel mechanism responsible for blood vessel injury in Sickle Cell Disease (SCD): microparticles derived from sickle cells deliver heme to the vascular endothelial cells causing oxidative damage. Sickle Cell Disease (SCD) is an inherited blood disorder caused by a single base mutation in the DNA of affected patients, producing abnormal hemoglobin molecules. In SCD, red blood cells…

    largely an alpha-helical protein which binds heme as a redox cofactor. The “heme nitrovinyl” group is specifically where nitrite modification of the heme macrocyle occurs in HRP, in the presence or absence of hydrogen peroxide. It’s regioselective at the 4-vinyl group leading to the formation of the heme 4-nitrovinyl moiety. This work investigated the structural properties of the adducts formed upon the reaction of ferric HRP with nitrite by resonance Raman spectroscopy. In the absorbance…

    mimic those of a hundred other conditions. Each type of porphyria has the same root cause which is the production of heme in the body. Heme is a component of hemoglobin which is a protein in red blood cells that carries oxygen from the lungs to the rest of the body. It also is an iron-containing compound used throughout the body in the role of breaking down chemicals so they can be removed from your body. (Kujtan 2005). Heme is made mainly in the bone marrow and the liver through the…

    Prophylactic hemin is a porphyrin chelate of iron, derived from red blood cells. Panhematin® is one of many prescribed medications for the treatment of acute intermittent porphyria attacks. Hemin is administered to avoid the progression of generalized pain to a neurological crisis. Because delta-aminolevulinic acid, the first step in heme synthesis, is regulated by a heme feedback mechanism, it was determined that acute porphyrias represent a deficiency in hepatocytes (Bissell & Wang, 2015). …
