Elaborate the main functions of inorganic nutrients and minerals in food
Answers
Inorganic nutrients include nutrients such as iron, selenium, and zinc, while organic nutrients include, among many others, energy-providing compounds and vitamins. A classification used primarily to describe nutrient needs of animals divides nutrients into macronutrients and micronutrients.
Minerals are inorganic substances required by the body in small amounts for a variety of functions. These include the formation of bones and teeth; as essential constituents of body fluids and tissues; as components of enzyme systems and for normal nerve function.

Answer:
A number of inorganic elements (minerals) are essential for the growth of living things. Boron, for example, has been demonstrated to be required for the growth of many—perhaps all—higher plants but has not been implicated as an essential element in the nutrition of either microorganisms or animals. Trace amounts of fluorine (as fluoride) are certainly beneficial, and perhaps essential, for proper tooth formation in higher animals. Similarly, iodine (as iodide) is required in animals for formation of thyroxine, the active component of an important regulatory hormone. Silicon (as silicate) is a prominent component of the outer skeletons of diatomaceous protozoans and similar organisms and is required in them for normal growth. In higher animals the requirement for silicon is much smaller. A less obvious example of a specialized mineral requirement is provided by calcium, which is required by higher animals in comparatively large amounts because it is a major component of bone and eggshells (in birds); for other organisms, calcium is an essential nutrient but only as a trace element. Mineral elements in wide variety are present in trace amounts in almost all foodstuffs. It cannot be assumed that the nonessential mineral elements play no useful role in metabolism
