Manganese is a chemical element with the symbol “Mn” and atomic number 25. It is a gray-white metal with a variety of industrial applications, including the production of steel, batteries, ceramics, and fertilizers. Manganese is also an essential micronutrient for living organisms, playing a critical role in various biological processes. It serves as a cofactor for enzymes involved in antioxidant defense, bone formation, carbohydrate metabolism, and the synthesis of certain neurotransmitters. Dietary sources of manganese include nuts, seeds, whole grains, leafy vegetables, and tea. Manganese deficiency is rare but can lead to impaired growth, skeletal abnormalities, and altered glucose metabolism. Conversely, excessive manganese exposure, particularly through inhalation of manganese dust or fumes in occupational settings, can cause neurological symptoms known as manganism. Therefore, maintaining appropriate manganese levels is essential for overall health.
