Manganese 50 µg Mn/L. A protein called DMT1 is the major transporter in manganese absorption from the intestine, and may be the major transporter of manganese across the blood–brain barrier. DMT1 also transports inhaled manganese across the nasal epithelium. The proposed mechanism for manganese toxicity is that dysregulation leads to oxidative stress, mitochondrial dysfunction, glutamate-mediated excitoxicity, and aggregation of proteins. Manganese Manganese is a chemical element with symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a metal with important industrial metal
Manganese(III) acetate Manganese(III) acetate Manganese(III) acetate describes a family of coordination complexes with the approximate formula Mn(OCCH). All are brown solids, which are soluble in acetic acid and water. These compounds are used in organic synthesis as oxidizing agents. Compounds with the formula Mn(OCCH) have not been verified. Instead manganese(III) acetate adopts the structure reminiscent of those of basic chromium acetate and basic iron acetate. For this reason, manganese(III) acetate is sometimes referred to as basic manganese acetate. The formula is [MnO(OCCH)L]X where L is a ligand and X is an anion. The coordination polymer [MnO(OCCH)]OCCHHOCCH has been crystallized. It is usually
