Metal ions and their Biological Functions in Human Body.

Metal ions are naturally occurring inorganic substances required in humans in a certain amount by mg/day. They are essential components of biological structures and have an important effect on and play a key role in a variety of the process necessary for life throughout mediating vital biochemical reactions. The role of essential nutrient metal ions as (Na+, K+, Ca۲+, and Mg۲+) often deficient in our food stuffs, its vitally essential in the function of the human body. Excessive levels, a level higher than needed for biological functions, of these elements can be toxic for the body health. Therefore, it has been found that the imbalances in the optimum levels of trace elements may adversely affect biological processes and are associated with many fatal diseases..In the recent study, ۱۵ samples from deferent patients in ages (۱۸-۴۵) and deferent living environments have been taken from Hawari hospital Kidney division, Benghazi, Libya. The samples were treated by separation of serum from the blood without any chemical treatment. The studied values were measured by spectrophotometer as element analysis. The studied values for metal ions (Na+, K+, Ca۲+, and Mg۲+) in serum samples, clearly reflect the lack of healthy food taken by the patients, which have caused some decrease in the normal values, even though still under control. The results showed a satisfactory values comparing with the normal values confirmed by WHO.
