The human body cannot directly absorb macromolecular substances, so is water a macromolecular substa

Water is not a macromolecule, and the absorption of water and the absorption of other substances is not a channel, as the high school biology book makes it very clear. The selective permeability of the cell is recognized by proteins on the outside of the cell membrane, and the carrier is required for transport, while the absorption of water depends only on the difference in concentration between the inside and outside of the cell. That's why saline can only be, too thick will dehydrate your cells, too much will make the cells overabsorb, burst, and then cause hemolysis, finish.

This is why normal saline can only be the reason that water is not a macromolecule, transportation needs a carrier, and the absorption of water only depends on the difference in concentration between inside and outside the cell, and the absorption of water and the absorption of other substances is not a channel, and the high school biology book says it very clearly. The selective permeability of cells is recognized by the proteins on the outside of the cell membrane, too concentrated will dehydrate your cells, and too much will cause the cells to overabsorb water and burst.

Water is a small molecule substance, like proteins, polysaccharides, fats are called macromolecular substances, to be decomposed into small molecules to be absorbed, water in and out of the cell depends on the concentration of the fluid inside and outside the cell, the concentration is high, it is easy to enter and exit the cell, no carrier or energy, as long as it passes through the protein channel on the cell membrane can enter the cell.

Water is directly absorbed, it is a small molecule. He can pass through the protein channels of the cell membrane.

Should it be directly absorbed, it should go through a process of transformation, or the water in the human body is **?

How can water be a macromolecule? There are only three atoms. How many atoms do you look at the structural formula of glucose?

The molecular structures of amino acids and ribonucleic acids are also relatively complex.

Whether the beneficial minerals in water, especially calcium, can be absorbed by most calcium-deficient groups in China has always been a matter of endless debate. According to the American Medical Journal, the minerals needed by the human body come primarily from food, not from drinking water. It is generally accepted in the medical community that all the minerals needed by the human body can be obtained from food.

Organic minerals formed by plant photosynthesis are beneficial for absorption by the body. On the contrary, the various minerals in water exist in an inorganic state and are difficult for the body to absorb. So, why risk drinking water that contains harmful substances when people can get the minerals they need from food?

For example, if the body is deficient in calcium in daily life, it should be obtained from other foods such as milk (the minerals contained in 1 cup of milk are the sum of the minerals contained in 1200 glasses of water) or calcium tablets"Active calcium"(organic calcium). At this time, even if there is a large amount of calcium in the drinking water, it is useless, and the substances that are ingested into the body and not absorbed will be excreted through the liver, kidneys and other organs, so that the internal organs will bear an additional burden.

In fact, only living plants can absorb and utilize the inorganic minerals in the soil, and only the organic compounds that have been converted by plants can be absorbed and utilized by humans and animals. It is well known that although there are nutrients in the soil, humans can only indirectly absorb the nutrients in those soils through food.

Now people's living standards have been greatly improved than before, the dietary structure has also been greatly improved, chicken, duck, fish, meat appear in the daily dishes, in winter you can also eat summer fruits, and the above foods are rich in minerals and trace elements, they are beneficial to be absorbed by the human body.

With the development of society, the pollution of our living environment is becoming more and more serious. Pollutants enter the human body through air, water, food and other ways, some of which are excreted through urine, and some of which will enter the human organs and blood, so people require hygiene and nutrition for food, purification of the air, and cleanliness of drinking water, only in this way can the metabolism of the human body be promoted, so that the otherwise healthy body is not damaged or less.

In short, you don't have to think too much about drinking water, drinking water is supplementing water, and you don't have to worry about nutrition. As for what kind of water is good to drink, it should depend on the economic conditions and whether the choice is really pure water.

Yes, it will enter the human body through **. It's like urinating after staying in the water for a long time.

There are both organic and inorganic matter!

The trace elements needed by the human body are inorganic! All kinds of calcium and iron supplements are inorganic!

Rice, vegetables, and fish are all organic matter that provides a lot of carbohydrates, proteins, and fats!

There are both organic and inorganic substances in the human body, and people can absorb both organic and inorganic matter!

Both are inorganic substances mainly water and minerals, and organic substances are mainly proteins and fats.

There are both organic and inorganic matter!

The trace elements needed by the human body are inorganic! All kinds of messy and ruined seeds, calcium and iron supplements are inorganic!

Rice, vegetables, and fish are all organic matter that provides a lot of carbohydrates, protein, and fat hunger!

There are both organic and inorganic substances in the human body, and companion people can absorb both organic and inorganic matter!
