BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Trace minerals (microminerals) The body needs trace minerals in very small amounts. Note that iron is considered to be a trace mineral, although the amount needed is somewhat more than for other microminerals. Other trace nutrients known to be essential in tiny amounts include nickel, silicon, vanadium, and cobalt.

Detailed explanation-2: -Microminerals, including iron, zinc, copper, selenium, manganese, iodine, chromium and molybdenum are essential for a vast array of physiological functions, as well as for normal growth and development.

Detailed explanation-3: -Micro minerals are often referred to as trace minerals, meaning they are present at low levels in the body or required in smaller amounts in the animals diet. Micro minerals include chromium, cobalt, copper, fluorine, iodine, iron, manganese, molybdenum, selenium, and zinc.

Detailed explanation-4: -An element is considered a trace element when its requirement per day is below 100 mg. The deficiency of these elements is rare but may prove fatal. Examples include copper, iron, zinc, chromium, cobalt, iodine, molybdenum, and selenium.
