关于营养的英文文献论文

这个范围也太宽了吧，要看具体内容。动物营养学的期刊很多，比如：畜牧方面的：Journal of animal science ，Poultry science ，The Journal of nutrition。兽医方面的：American Journal of veterinary research，Theriogenology等等很多啊。看你具体要哪方面的

Trace elementsThe human body is composed by 60 various elements. According to the element in the human body, can be divided into different levels of two kinds of elements and trace elements. The total weight of all the human element, such as the above carbon, hydrogen, oxygen, nitrogen, calcium, phosphorus, magnesium, sodium, called macro amount. The total weight of all the human element, such as below iron, zinc, copper, manganese, chromium, selenium, molybdenum, cobalt, fluorine, called the trace element. Trace elements in human body, such as zinc content is slim body total weight only three millionth 13. Iron is only 100 elements in human body, although the content, but with person's survival and health. They absorb excessive, insufficient, or lack of different degrees of human physiological cause abnormal or disease. 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 function. Note the trace elementTrace elements and human healthMust be directly or indirectly by soil supply. 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, etc. This each trace element has its special physiological function. Although they are very content in the human body, but some of the human body to maintain metabolism is the decisive is necessary. Once the lack of these essential trace elements, the human body will appear even life-threatening diseases. Such as zinc deficiency can lead to mouth, eyes, rectal or the red, pimples, wen rash. As iron constitutes one of the major components of hemoglobin, lack of iron may cause iron-deficiency anaemia. 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 infection. The trace elements in disease, cancer, prolong life etc are also plays a role that cannot be elements in human body, although the content of small, but with the long and health. Such as zinc deficiency can lead to mouth, eyes, rectal or the red, pimples and eczema. As iron constitutes one of the major components of hemoglobin, lack of iron may cause iron-deficiency anaemia. Human needs from the various elements in the food. 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 elements. Conversely, can cause lack of certain 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 functions. Trace elements within the first constitutes an important carrier and electronic transfer system. Iron exists in hemoglobin and muscle protein, in their execution of carrying oxygen in the process of oxygen and iron plays an important 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, metal. Valley Dan Kennedy pulse peroxidase is typical of nonmetal enzyme inhibition, it is free. Remove peroxide. Protect membrane integrity, etc. This enzyme molecule contains four selenium atoms. Zinc is not only the carbonate phenolic enzyme, DNA polymerases and RNA polymerase kinds of enzymes, and a necessary component of enzyme activity with 100. Manganese as ion sex strong trace elements are valid activation agent, can activate enzymes catalysis for biosynthesis of thyroid hormone necessary, While maintaining the subject in zinc insulin in structure, every indispensable insulin molecular combining two zinc atom. Vitamin than is the thymus krabi steep and eventually DNA synthesis nuclear biosynthesis and transcription necessary phenol-o-methyl shift. 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 rearrangement. The nucleic acid is genetic information carriers. Trace elements of the physical and chemical properties of nucleic acid can be influenced. Various RNA polymerase contains zinc, and nuclear yesterday acid oxidoreductase functions depend on dry iron.
