MANGANESE AND THE ROLE IT PLAYS IN THE HUMAN BODY
Introduction
Manganese is one of sixteen known minerals that are essential within the human diet (wardlaw). Minerals, such as manganese, are considered essential to the diet of humans if their absence results in physiological or structural abnormalities and their presence prevents disease/illness (wardlaw). The body utilizes manganese primarily in energy metabolism and within the antioxidant systems (wardlaw). Manganese is found primarily in parts of the body such as the liver, pancreas, kidneys and bones (Ehrlich).
The Chemical Properties of Manganese
Manganese (Mn) is a member of the periodic family of transition metals. Transition metals have one or more stable ions that do not have complete d-orbitals. Manganese has the atomic number twenty-five, ie. the nucleus contains twenty-five protons. Taking into consideration the abundance of various Manganese isotopes, the atomic weight was found to be 54.9380amu.
Dietary Reference Intake
Manganese does not have a Recommended Dietary Allowance (RDA) due to insufficient information, however, the Food and Nutrition Board has set an Adequate Intake. The Adequate Intake was formulated based on observed and experimentally determined approximations of manganese by populations of good health status. In healthy adults, the AI for men is 2.3mg/day and 1.8mg/day for women (wardlow). The need for dietary manganese increases with pregnancy and lactation (2.0-2.6 mg/day) (linus pauling).…
