Anemia results from insufficient oxygen supply, often because of a decrease in hemoglobin (Hb)blood levels.Approximately 65 to 70 percent of total body iron resides in Hb. In third-world countries, however,scarcity of dietary iron is a major contributor to anemia. The information illustrates one important fact about disease that results from metal deficiency, namely, the need for an adequate supply of essential metals in food. A related aspect.one of greater interest for bioinorganic chemistry, is yhe requirement that metals be adequately absorbed by cell, appropriately stored, and ultimately inserted into the proper environment to carry out the requisite biological funtion. For iron,these tasks, environment to carry ot the requisite biological function.For iron,these tasks,
