The amount of iron in the blood is not low, 45% (volume) of the blood is red blood cells, and one red blood cell contains about 100 million hemoglobins.
Each hemoglobin contains 4 hemes.
molecules, each heme molecule contains 1 iron atom. So a single red blood cell contains nearly 1.1 billion iron atoms. Although only a very small amount of iron in the mouth is released in the form of ions and is felt by the tongue, the human sense of taste is quite sensitive, so such a small amount of iron ions can also be felt.
On the other hand, if you lick iron or rust with your tongue, only a very small amount of iron is released in ionic form and felt by your tongue (otherwise you will see the iron dissolve like sugar). Blood is the "sea" of the life activities of human cells. Human blood consists of two parts: plasma and blood cells.
Blood is a yellowish liquid. Blood cells can be divided into red blood cells.
White blood cells and platelets.
In three parts, human hemoglobin is an iron-containing protein, and the raw material for red blood cell synthesis contains iron, so it is normal to have a rusty smell. <>

Human blood should smell bloody, not rusty. Blood has a special taste, which is produced by plasma and substances in the blood, and the hemoglobin in the blood is not rusty iron, and there is no rust smell. Ferric sulfate has some rust smell but is not very strong, because it is trivalent iron ions, and the rusty iron filings have an obvious rust smell, if the seriously rusty iron filings stick to your hands in summer, it is best to have a little water, at this time the rust smell is the strongest.

1. Its main components are plasma, blood cells, genetic material, i.e., chromosomes and genes, and contains various nutrients, such as inorganic salts, oxygen, cell metabolites, hormones, enzymes and antibodies.
2. The reasons for the taste of iron in blood are as follows:
1. Plasma proteins contain haptoglobin and ferroportin
1) Haptoglobin.
About 10% of the degraded Hb is released into the blood circulation every day to become free HB outside the red blood cells, and the molecular weight of Hb and Hb can reach after combining with HP to form HB-HP complex, which cannot penetrate the glomeruli, so as to prevent the loss of free hemoglobin from the kidneys and the loss of iron contained in Hb. Ensure that iron is reused for anabolism.
2) Ferroporters.
The physiological function of iron transporters is to transport iron to tissues and cells that need it. Hemoglobin is catabolized every day, releasing about 25mg of iron. Free iron is toxic, and when it binds to TF, it not only reduces toxicity but also transports iron to the iron-demanding site.
2. Iron is indispensable for the biological activity of many iron-containing proteins, such as hemoglobin, myoglobin, cytochrome, peroxidase, etc. Thus, any growing, proliferating cell has receptors for ferroportin on its membrane. TF carrying Fe+ binds to the receptor and enters the cell through endocytosis for intracellular synthesis and utilization.
To sum up: blood contains a certain relative amount of iron, so blood has a certain taste of iron to a relative extent.
-
It is because iron has a similar fishy smell to blood, and its fishy smell** is bivalent iron ions.
-
The main ingredient in blood is iron, iron has a general fishy smell, and the blood smell that people often say is actually the smell of elemental iron.
-
Blood is made up of serum and blood.
Cells (red blood cells, white blood cells (monocytes, lymphocytes, and granulocytes), and platelets).
The smell of iron you smell is due to the presence of ferrous iron in hemoglobin, an important component of blood cells. Its presence is conducive to carrying oxygen, transporting oxygen to tissues and organs throughout the body. Carbon monoxide poisoning is caused by CO turning Fe2+ into Fe3+, losing the ability to bind to oxygen, and depriving the body of oxygen.
-
It may be because the human blood contains iron as a nutrient.
-
Mine too, and the flavor is still bigger than before, probably because of the psychological effect, alas.
Because there is iron 107 in the blood, it is oxidized when exposed to air! Human blood includes two parts: plasma and blood cells, blood cells can be divided into three parts: red blood cells, white blood cells and platelets, human hemoglobin is an iron-containing protein, so you find that your blood has a strong rust smellBecause human blood contains a large amount of ferric ions.
Whereas, rust is made up of ferric tetroxide. Whereas, ferric tetroxide contains a large amount of ferric iron. So you'll smell a smell of rusty iron.
-
Because there are ferrous ions in the blood, it smells of iron.
-
Because you have iron in your blood! It may also be that the iron pot at your home has been eaten by you!
-
The blood is ferrous iron, when the blood leaks into the air, the ferrous iron will quickly oxidize to iron, so it will have that taste, human blood contains ferrous ions, when the blood is exposed to the air, it is rapidly oxidized into 3-valent iron ions. The composition of rust is Fe2O3. It is also 3-valent iron ions, so it is quite normal to smell rust.
-
The smell of rust is produced by ferric ions, which are easily oxidized into ferric ions in the air, and even if they are in small amounts, they will bring a very sensitive smell...
In the same way, there is ferric iron in the blood, all of which has the taste of iron.
-
Human blood contains ferrous ions, which are rapidly oxidized to ferric 3 when exposed to air. The composition of rust is Fe2O3. It is also 3-valent iron ions, so it is quite normal to smell rust.
-
There is a lot of hemoglobin in the blood, and hemoglobin is made up of heme and iron, so it smells of iron.
-
The porphyrin ring of heme is covered with a bivalent iron.
-
Blood is made up of heme and second-order iron, and smells similar to iron.
-
Biologically, blood needs iron ions to transport oxygen, but not in high amounts.
-
Tea bud rose barley tea to remove moisture and beautify the skin.
It could be caused by sun exposure.
If this is the case, as long as there is nothing else unwell in the body. It will be fine in a few days, you can observe it for a few days without worrying. This condition also falls under armpit odor. >>>More
It is not a mixture, and it is not possible to match the valency directly by looking at the chemical formula, and it can also be detected by chemical methods that it contains ferric iron (reducing property) and ferric iron (oxidizing property).
The normal color of blood is red, because the blood contains a large number of red blood cells, and the red blood cells contain blood red, and the blood red is red, so the blood appears red. At the same time, according to the different oxygen concentration in the blood, the blood is divided into venous blood and arterial blood, the oxygen content in the venous blood is lower, the blood is dark red, and the oxygen content in the arterial blood is higher, and the blood is bright red. There are also patients with anemia, due to the decrease in the number of red blood cells, the concentration of hemoglobin decreases, the patient's blood is reddish, and the more severe the anemia, the lighter the color of the blood.
This is because most animals rely on iron-containing hemoglobin to transport oxygen, and iron will appear red when combined with oxygen; The protein of the LAL amoebocyte lysate, which transports oxygen, contains copper, which appears blue when combined with oxygen. In fact, there are also such phenomena in life, such as knives and iron doors rusting and turning red, and swimming pools turning blue because of copper sulfate disinfection. >>>More
People with white blood generally suffer from hyperlipidemia, due to abnormal lipoprotein metabolism or lipidosis, which is a congenital inherited metabolic disease, and specific tests need to be further improved. Since this case is very rare, its diagnosis and ** are very difficult, and at the moment it is mainly symptomatic**, and it may be difficult to completely **.
