Minerals :-
Minerals are inorganic substances that
play an important role in a variety of metabolic reactions, as cofactors. They
form one of the essential components of the diet. They are essentially divided
into two major groups: macronutrients which are required in large amounts such
as calcium, magnesium, sulphur, sodium, potassium and chloride; and
micronutrients or trace elements which are required in very small quantities in
the diet.
- Those recognized as essential for
human nutrition and for which sufficient information is available to
justify the recommended dietary allowances (RDA) such as zinc, iodine and
iron.
- Those probably essential for human
nutrition (known to be essential in animals, but insufficient information
is available regarding humans). Copper, molybdenum, fluorine, selenium,
cobalt, chromium and manganese are examples of this type.
- Those present in human tissues, but
have not yet been proved to be essential, for example, nickel, silicon,
tin and vanadium.
Specialized instruments tike flame photometer
and absorption spectrophotometer need to be used for the detection of minerals.
