Sodium is not a trace element in animals It is not a trace element in plants

For animals, sodium is an essential element and not a trace element. (Think of sodium chloride, which is the table salt we eat, and there is a lot of urine in it, how can it be counted as trace elements).

According to the latest edition of Plant Physiology (Higher Education Press), it has been proved that there are 16 kinds of mineral elements necessary for plant growth, that is, silicon, sodium and nickel are also listed as essential mineral elements for plants, of which silicon is a large number of elements, and sodium and nickel are trace elements.

Silicon, sodium, and nickel all exist in plants, but in the past, they were regarded as non-essential elements due to cultivation technology and impure medicines, but now their physiological roles are clarified and they have the conditions to become essential mineral elements.

Sodium accounts for the dry weight of the plant body, is absorbed in ionic form, and is required for the growth of most C4 plants and sedum acid-metabolizing plants (e.g., sedum, ground roots, cactus, etc.). It catalyzes the regeneration of phosphoenolpyruvate. When sodium is deficient, these plants show yellowing and necrosis.

In addition, sodium can also increase the turgor pressure of C3 plant cells, thereby promoting growth, and some Na can also replace the effect of K to improve the permeability of cell fluid.

Sodium is a trace element in the human body. Sodium is a metal element, in the periodic table in the middle of the third cycle, group a, is a representative of alkali metal elements, soft texture, can react with water to form sodium hydroxide, release hydrogen, chemical properties are more active. Sodium is widely distributed in the form of salts on land and in the sea, and sodium is also one of the important components in human muscle tissue and nerve tissue.

There are about 70 trace elements, which refer to the elements that are lower than the human body in the human body, including iron, iodine, zinc, selenium, fluorine, copper, cobalt, cadmium, mercury, lead, aluminum, tungsten, barium, titanium, niobium, zirconium, rubidium, germanium and rare earth elements.

1. Sodium is not a trace element of the body, but a macro element. Sodium has the physiological functions of maintaining acid-base balance, regulating osmotic pressure, constituting extracellular fluid, and maintaining blood circulation. Under normal circumstances, the sodium content of the human body is 135-145mmol l.

2. The body's sodium and water are closely linked, if you eat too much salt, you will be thirsty, and the water intake will increase significantly, but the urine will not be excreted immediately. Therefore, it is closely related to blood volume, and the body will be weak when there is less sodium, but too much sodium will also cause damage.

Macroelements, also known as macronutrients. Generally speaking, it refers to the elements whose content accounts for more than 1/10,000 of the total weight of organisms, such as: calcium, magnesium, potassium, nitrogen, sulfur and phosphorus and other salts, and the content of each liter is about grams.

On the contrary, it has long been known that iron (hematopoiesis) is an indispensable element, and its concentration is maintained at 1 part per 100,000. In addition, due to the progress of pharmaceutical refining and hydroponic technology, some indispensable elements have been determined, such as zinc, manganese, copper, etc., and their suitable concentrations are about one millionth. The various elements below iron are called trace elements or trace nutrients.

Although we consume salt every day, because the sodium content in perspiration is also very high, the sodium content in the human body is actually not large.

A large number of elements ......

The trace elements are only zinc, iron, boron, copper, molybdenum, and manganese (notation: new iron b Astro Boy!). ）

Everything else should be a lot of elements. The reason for that, of course, is the measured ......Don't know what to explain. If you think about it, eating so much salt every day and having so much sodium in it is definitely not a trace element ......

In the human body, sodium is a macroelement.

There are 11 kinds of macroelements in the human body, namely carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus, chlorine, calcium, potassium, sodium, and magnesium. Their amounts add up and account for about a percentage of body weight. This includes sodium.

Hello dear netizens:

First, let me introduce myself. I am a medical student studying clinical practice, mine can only represent personal opinions, do not have any authority, and are for reference only. However, please be assured that mine is cautious and confident as a member of the brilliantly knowing team.

Not exactly. The carrier material of life is protein, whether it is animals or plants, the so-called large elements, generally have carbon, hydrogen, oxygen and nitrogen. Trace elements are related to the complexity of life activities, such as the content of iron in the human body is related to the transport of oxygen in the blood, and the content of iron should not be too low.

Not all plants contain iron. Therefore, it is not possible to generalize.

Know, help others, be happy yourself, and hope my answers will be helpful to you.
