Assignment Trace elements, what are the trace elements required by the human body

What are trace elements? What do trace elements do to the human body?

The amount of elements in the human body is very small, and those elements that are lower than the body weight are called micro.

quantity element. Although the amount of trace elements in the human body is very small, it has a positive effect on human health.

plays an important role. They are involved as components of enzymes, hormones, vitamins, and nucleic acids.

Metabolic processes of life. In a sense, trace elements are better for the body than vitamins.

More needed. At present, there are more than 20 kinds of trace elements discovered, and it is known that trace elements such as iron, iodine, copper, meng, zinc, diamond, chromium, selenium, Shao, fluorine, silicon, tin, vanadium and other trace elements and the life of the body.

The activities are closely related.

1) It plays a specific role as a activation center in the enzyme system.

Trace elements keep the subunits of enzyme proteins together, or put enzymes into action.

The chemical is bound to the active center of the enzyme. Iron, copper, zinc, drill, manganese, aluminum, etc., can be and.

Coordination groups or molecular genes such as sparse groups, colloidal groups, isopyrazole groups, press groups, hydroxyl groups, etc.

synthesis, forming complexes, which are present on the side chains of proteins.

2) It plays a specific physiological role in hormones and vitamins.

Certain trace elements are components of hormones or vitamins and important active parts.

If these trace elements are lacking, the corresponding hormones or vitamins cannot be synthesized, and the physiological functions of the body will inevitably be affected. Such as iodine and thyroid hormones.

The diamonds in vitamin B12 are all trace elements of this kind.

3) The role of transporting elements.

Some trace elements have the effect of transporting common elements in the body. Iron is blood.

Carriers of oxygen in globin cannot synthesize hemoglobin without iron, and oxygen cannot be used.

Transport, tissue cells cannot be metabolized, and the body cannot survive.

4) Regulate fluid osmotic pressure and acid-base balance.

Trace elements are in the body fluid, synergizing with potassium, sodium, calcium, magnesium and other ions, and can be adjusted.

The role of osmotic pressure and the pH of body fluids to maintain the normal physiological functions of the human body.

5) Affect nucleic acid metabolism.

Nucleic acids are carriers of genetic information, and nucleic acids contain quite a lot of trace elements such as chromium, iron, zinc, manganese, copper, and nickel, which can affect the generation of nucleic acids.

Thank. Therefore, trace elements play an important role in heredity.

6) Anti-cancer and anti-cancer effects.

Some trace elements have certain anti-cancer and anti-cancer effects. Such as iron, selenium, etc. on the stomach.

Intestinal cancer has an orange anti-effect; Magnesium has a positive effect on malignant lymphomosis and chronic leukemia.

Use; Zinc has an orange anti-effect on esophageal cancer and lung cancer; Iodine has effects on thyroid cancer and breast cancer.

Citrus anti-effect.

Trace elements refer to elements that are necessary for biological life, but the amount required is very small. It is indispensable for maintaining normal life activities.

There are many trace elements that make up living organisms, such as fe, mn, zn, cu, b, mo, etc.

There are 14 kinds of essential mineral elements for plants, among which N, P, K, S, CA, and mg belong to a large number of elements; Fe, Mn, B, Zn, Cu, Mo, Cl, Ni belong to trace elements.

Don't study too hard, maybe you've been too tired lately, recuperate, and if you can't do it, go to Chinese medicine to see.

Poor digestion and absorption caused by bad bile.

To add some DHA, I gave it to my son.

Livestock and poultry growth and body metabolism, in addition to the need for common calcium, phosphorus, sodium, potassium and other mineral elements, there are many elements are also indispensable, but the need for these elements is very small, and the content in the animal body only accounts for less than 1/10,000 of body weight, so these elements are called trace elements. At present, 14 trace elements are known to be necessary for the human body, and these 14 trace elements are iron, fluorine, selenium, zinc, copper, molybdenum, cobalt, chromium, manganese, iodine, nickel, tin, silicon, and vanadium. The trace elements involved in the growth of livestock and poultry are copper, cobalt, iodine, zinc, selenium, fluorine, manganese, etc.

Trace elements are important components of many enzyme systems in the animal body, and some vitamins and hormones also contain trace elements, so trace elements play a very important role in the growth and metabolism process of animals, and once deficient, it will cause diseases. Excessive intake of trace elements can cause poisoning to livestock and poultry. Because the trace elements contained in water, soil and plants have certain differences in various places, the deficiency of trace elements is often regional, such as in the northeast, northwest and north China of many places are selenium deficiency areas, livestock and poultry selenium deficiency diseases are more.

The human body is an organism made up of various elements. According to the proportion of various elements in the human body, it can be divided into macro elements and trace elements. There are 11 types of macro elements, and they are listed in order of how much is needed

Oxygen, carbon, hydrogen, nitrogen, calcium, phosphorus, potassium, sulfur, sodium, chlorine, magnesium. Among them, oxygen, carbon, hydrogen and nitrogen account for 95 of the human body's mass, and the rest account for about 4, in addition, trace elements account for about 1. Among the essential elements for life, there are 14 kinds of metal elements, of which the content of potassium, sodium, calcium and magnesium accounts for more than 99 of the total number of metal elements in the human body, and the content of the remaining 10 elements is very small.

It is customary to refer to the elements that are higher than the proportion in the human body as macro elements, and the elements below this value as trace elements. Such as iron, zinc, copper, iodine, lead, etc. If the human body lacks a certain macro element, it will cause the human body to dysfunction, but this rarely happens, and the average diet contains more than enough macro elements.

Trace elements are divided into three categories: essential elements, non-essential elements and harmful elements. Although essential trace elements are found in small amounts in the body, their role in the life process cannot be underestimated. Without these essential trace elements, the activity of enzymes will be reduced or completely lost, the synthesis and metabolism of hormones, proteins, and vitamins will be impaired, and it will be difficult for human life processes to continue.

As a result, many diseases in children are related to the elements, and a lack or too much of it can lead to the disease.

The human body is made up of more than 80 elements. According to the different content of elements in the human body, they can be divided into two categories: macro elements and trace elements. All elements that account for more than 1/10,000 of the total weight of the human body, such as carbon, hydrogen, oxygen, nitrogen, calcium, phosphorus, magnesium, sodium, etc., are called macro elements; All elements that account for less than 1/10,000 of the total weight of the human body, such as iron, zinc, copper, manganese, chromium, selenium, molybdenum, cobalt, fluorine, etc., are called trace elements (iron is also known as semi-trace elements).

The amount of trace elements in the human body is really negligible.

These are two different concepts.

Not the same kind of nutrients.

Trace elements are for the macro elements in minerals, and trace elements are divided into 3 categories:

1.Essential: iron, iodine, zinc, selenium, copper, molybdenum, chromium, cobalt, etc. 8 kinds 2

The human body may need to quantity elements: manganese, silicon, nickel, boron, vanadium, etc. 5 kinds 3It has the potential to be poisoned, but when it is low, it may have an essential function for the human body:

Fluorine, lead, cadmium, mercury, arsenic, aluminum, lithium, tin.

The "trace elements" in nutrition are relative to the "macro (macro) elements", in addition to vitamins, including minerals, etc., such as human health and life-related essential trace elements have 18 kinds, namely iron, copper, zinc, cobalt, manganese, chromium, selenium, iodine, nickel, fluorine, molybdenum, vanadium, tin, silicon, strontium, boron, rubidium, arsenic, etc.

It is a detailed introduction to trace elements in Baidu Encyclopedia.

Trace elements are combined with proteins and other organic groups to form biological macromolecules such as enzymes, hormones, and vitamins, which play important physiological and biochemical functions. Trace elements first constitute an important carrier and electron transport system in Hugh.

Vitamins are found in food in the form of provitamin (vitamin precursors), vitamins are not components of the body's tissues and cells, it does not produce energy, its role is mainly to participate in the regulation of the body's metabolism.

Vitamins 3 words.

Trace elements 4 words.

First of all, the child's nutrition should keep up, and secondly, it should take him out of life and cultivate her good habits of being careful and careful.

If you want to learn well, you must first learn to do housework.

To cultivate his good study habits, it is not that there is a lack of trace elements.

First of all, you must realize this problem, since it is a trace element, the human body's demand for it is very small, lack is very harmful, excessive intake will also cause harm.

So far, there are 18 essential trace elements that have been identified as related to human health and life, namely iron, copper, zinc, cobalt, manganese, chromium, selenium, iodine, nickel, fluorine, molybdenum, vanadium, tin, silicon, strontium, boron, rubidium, arsenic, etc.

For example, copper deficiency can easily cause malnutrition, anemia, neutropenia, and coronary heart disease. But excess copper can also cause disease because copper is a heavy metal.

Harmful trace elements such as lead, mercury, etc. can cause disease. (Trivalent chromium is a beneficial element, while hexavalent chromium is toxic.) Silver is a heavy metal,)

Lead, aluminum, mercury, etc., and other trace elements have a certain range, and more or less are harmful to the human body!!

Consult a pediatrician, pay attention to observation, and timely** help your child grow up physically and mentally healthy.

It is possible that it is a long body, and it will be like this when you sleep and grow your body when you are a child.

Children's inattention is caused by too many or too few trace elements in the child's body, such as the child's lack of microelement zinc. From the perspective of the natural laws of the five elements of Chinese medicine Feng Shui, children's inattention is caused by the imbalance of the five elements of yin and yang in the child's body, such as the child's fire will be easy to be active.

There are only two effective solutions: first, go to the hospital to check the trace elements and take the drugs to supplement the trace elements; Second, the child's four-round learning method adjusts the child's clothing, food, housing and transportation: help the child adjust the diet, wear the color of the bed sheet ** and other details of daily life, so as to balance the yin and yang elements in the child's body, improve the child's sleep quality, strengthen the child's brain development, so as to completely improve the child's inattention.
