Trace elementsThe human body is composed by 60 various According to the element in the human body, can be divided into different levels of two kinds of elements and trace The total weight of all the human element, such as the above 01 carbon, hydrogen, oxygen, nitrogen, calcium, phosphorus, magnesium, sodium, called macro The total weight of all the human element, such as 01% below iron, zinc, copper, manganese, chromium, selenium, molybdenum, cobalt, fluorine, called the trace Trace elements in human body, such as zinc content is slim body total weight only three millionth Iron is only 100 PPMTrace elements in human body, although the content, but with person's survival and They absorb excessive, insufficient, or lack of different degrees of human physiological cause abnormal or The most prominent role of trace element is closely related with the vigor of life, just like a match that size or less of the quantity can exert great physiological Note the trace elementTrace elements and human healthMust be directly or indirectly by soil According to the scientific research, so far, has been identified and human health and life of the essential trace elements about 18 kinds, namely with iron, copper, zinc, manganese, chromium, cobalt, nickel, selenium, iodine, fluorine, molybdenum, vanadium, tin, silicon, strontium, boron, rb, arsenic, This each trace element has its special physiological Although they are very content in the human body, but some of the human body to maintain metabolism is the decisive is Once the lack of these essential trace elements, the human body will appear even life-threatening Such as zinc deficiency can lead to mouth, eyes, rectal or the red, pimples, wen As iron constitutes one of the major components of hemoglobin, lack of iron may cause iron-deficiency Foreign had reported: the body contains iron, copper, zinc, all can weaken the immune mechanism to resist disease (power), reduce the disease-resistant ability, fuelling bacterial infections, and the higher mortality after The trace elements in disease, cancer, prolong life etc are also plays a role that cannot be Trace elements in human body, although the content of small, but with the long and Such as zinc deficiency can lead to mouth, eyes, rectal or the red, pimples and As iron constitutes one of the major components of hemoglobin, lack of iron may cause iron-deficiency Human needs from the various elements in the Due to various food contains element types and quantity is not identical, so in the normal diet, coarse, combined with meat or fish is tie-in XiLiang  slant, don't eat, not picky, can satisfy the need of various Conversely, can cause lack of certain Molecular biology research reveals, trace elements and protein and other organic by groups, formed the enzyme, hormone, vitamin etc biological macromolecules, plays an important physiological and biochemical Trace elements within the first constitutes an important carrier and electronic transfer Iron exists in hemoglobin and muscle protein, in their execution of carrying oxygen in the process of oxygen and iron plays an important Enzyme catalysts, life is far more than 1000 body found in the enzyme, about 50? The trace element to close to 70% or activate cells, enzyme system function quite wide: from weak to constitute the highly specific ion effect of compound enzyme and nonmetallic enzymes, Valley Dan Kennedy pulse peroxidase is typical of nonmetal enzyme inhibition, it is Remove Protect membrane integrity, This enzyme molecule contains four selenium Zinc is not only the carbonate phenolic enzyme, DNA polymerases and RNA polymerase kinds of enzymes, and a necessary component of enzyme activity with Manganese as ion sex strong trace elements are valid activation agent, can activate enzymes catalysis Iodine for biosynthesis of thyroid hormone necessary, While maintaining the subject in zinc insulin in structure, every indispensable insulin molecular combining two zinc Vitamin than is the thymus krabi steep and eventually DNA synthesis nuclear love biosynthesis and transcription necessary phenol-o-methyl The molecules of a drill relate to close the atomic structure parts, containing it ring of the compound - goo elim coenzyme is known to the most effective biological catalyst in one of many enzyme plays an unusual molecular The nucleic acid is genetic information Trace elements of the physical and chemical properties of nucleic acid can be Various RNA polymerase contains zinc, and nuclear yesterday acid oxidoreductase functions depend on dry
