Do you know anything about iron?

Iron is an indispensable element in the body, and iron is generally easy to lose, so it needs to be replenished from time to time, but iron supplementation cannot be blindly supplemented.

Iron is mostly found in the form of compounds in nature, and iron is easy to react with oxygen, sulfur, chlorine and other elements at high temperatures, and is easily soluble in inorganic dilute acids and concentrated hydrochloric acid.

Iron has hematopoietic function in the human body, participates in the synthesis of blood proteins, cytochromes and various enzymes, promotes growth, and is very good for the development of the human body.

Whether it is marble or granite, the stability of iron-bearing minerals determines the stone's resistance to weathering. Iron sulphide is the most unstable component, followed by biotite and chlorite.

Iron deficiency in the human body can cause microcytic anemia, decreased immune function and metabolic disorders; If the iron deficiency can lead to iron deficiency anemia, the person's face will be yellow, and the beauty will also be lost.

The iron-containing minerals in marble include iron carbonate, iron sulfide, iron oxide and iron-containing silicate minerals. The iron-containing minerals in marble have very different effects on marble due to their different compositions.

The dark color of iron-bearing minerals has a key impact on the decorative aesthetic value of granite. Dark minerals are concentrated in granite, and the stone is often black or green.

Effect of iron-bearing minerals on graniteIn addition to iron-bearing sulfate minerals, most iron-bearing minerals may exist in granite in the form of various chemical formulas.

Iron is a chemical element, its chemical symbol is Fe, and the atomic number is 26, and it is the most commonly used metal. It is a type of transition metal and is the second most abundant metallic element in the earth's crust. The iron group elements refer to some of the elements in period 4 of the periodic table, including:

There are 7 elements of Ti, V, Cr, Mn, Fe, Co and Ni, which belong to the transitional group of elements.

It has an important influence on the color of gemstones in the science of gemstones. They have similar atomic structures, have similar forms of existence and physical and chemical conditions of migration and precipitation in nature, and the difference in the number of electrons in the D layer often leads to the differentiation of this group of elements in the process of geological action.

Foods that contain a lot of iron: then the age is suspicious.

1. Pork liver contains milligrams of iron and milligrams of protein per 100 grams of pork liver. Pork liver is also rich in vitamin A and folic acid, and its nutrition is more comprehensive. However, pork liver contains more cholesterol, so it is not advisable to eat too much at one time.

2. Beef contains milligrams of iron and milligrams of protein per 100 grams of beef. Beef has high nutritional value and has the effect of strengthening the spleen and stomach, but the beef fiber is coarse.

3. Pork contains milligrams of iron and milligrams of protein per 100 grams of pork. Pork has the effect of moistening the intestines and nourishing the stomach.

4. Chicken liver contains mg of iron and mg of protein per 100 grams of chicken liver. Chicken liver is rich in heme iron, zinc, copper, vitamin A and B vitamins.

5. Pig kidneys contain milligrams of iron and milligrams of protein per 100 grams of pig kidneys. Pork kidneys are rich in zinc, iron, copper, phosphorus, B vitamins, vitamin C, protein, and fat.

6. Soybeans contain milligrams of iron and milligrams of protein per 100 grams of soybeans. Soybeans are highly nutritious and high in iron, but the iron they contain is slightly less absorbable than animal**.

1. Iron is composed of iron atoms.

2. Iron is widely distributed in life, and the content of the earth's crust is second only to oxygen, silicon and aluminum, ranking fourth in the earth's crust. Pure iron is a flexible and malleable silvery-white metal, which is used to make the iron core of generators and motors, and iron and its compounds are also used to make magnets, drugs, inks, pigments, abrasives, etc. In addition, the human body also contains iron, and +2-valent ferrous iron is an important component of hemoglobin, which is used for oxygen as much as a transfusion.
