Recently, the novel coronavirus.
Many people have been infected, but our country is actively protecting us, so we should learn to protect ourselves. Virus? What is it?
Can it be wiped out in high temperatures? In fact, this answer cannot be too absolute, most viruses can be eliminated under high temperatures, but some cannot be eliminated. Next, let me explain it to you!
Virus? It refers to a kind of smallest microorganism that cannot be seen under an ordinary microscope, and is an infectious body with life phenomena such as heredity, mutation, symbiosis and interference, which proliferates in a certain living cell, causing death or damage.
A virus is a non-cellular life form that consists of a nucleic acid.
Composed of long chains and protein coats, viruses do not have their own metabolic mechanisms and do not have enzyme systems.
There are three general viruses, which contain proteins and nucleic acids; Virus-like, containing nucleic acids and no proteins; Prions.
Contains only protein and no nucleic acids.
When the virus leaves the host cell, it becomes a chemical substance that has no life activity and cannot reproduce on its own. Once in the host cell, it can use the material and energy in the cell, as well as the ability to copy, transcribe, and translate, according to the genetic information contained in its own nucleic acids.
Generate a new generation of viruses like it.
Many people believe that boiling at high temperature can kill viruses and germs, play a role in disinfection, and even some spoiled foods can be safely eaten after boiling.
In fact, high temperature can destroy the structure of proteins, but not nucleic acids. Most of the viruses around us contain proteins and nucleic acids, so basically high temperatures can destroy viruses.
Boiling at high temperature is the most common disinfection method in daily life, and many germs can be killed by boiling water, however, this is not the case for all germs.
Some germs are quite stubborn in the presence of high temperatures, such as hepatitis B.
It takes 10 minutes for the virus to be destroyed at 100 degrees Celsius. And bacteria with spores such as Bacillus anthracis and tetanus.
Bacillus and so on, have stronger resistance to high temperature and high heat, botulinum toxin.
It can even survive for 5 hours at 100 degrees in boiling water. For other chemical toxins, such as solanine, aflatoxin.
High-temperature boiling water not only cannot effectively kill the virus, but even has the opposite effect of accelerating the diffusion of toxins and increasing the concentration. Therefore, high-temperature boiling is not a "universal cure" for sterilization and virus killing.
Finally, I believe you have learned whether high temperatures can destroy the virus. In fact, the best way to get rid of the virus is to not get the virus, but if we are infected with the virus, high temperatures may also be useful, but it is not the best way, so it is necessary to seek medical attention in time to avoid deterioration.
-
The virus can be eliminated in high temperatures, for example, the new coronavirus, which is very serious now, can be eliminated in 30 minutes if it lasts at a temperature of 56 degrees.
-
Yes, ordinary viruses can be completely destroyed after five minutes of disinfection in boiling water, and the spores of viruses take a long time.
-
Viruses can generally be destroyed at high temperatures, but some viruses require substances such as alcohol to completely destroy them.
-
Viruses are not heat tolerant, most of them can be destroyed by sustained high temperatures, and some cannot.
-
1. The virus can be disinfected at high temperatures.
2. Viruses and bacteria are denatured and inactivated by proteins at high temperatures, so that viruses and bacteria die, which can be used for disinfection.
3. General bacteria will die at 100 °C, but some heat-resistant bacilli or spores can still survive, so they will be sterilized at 121 °C for about 20 minutes.
4. When it reaches 85 °C, most bacteria lose their activity, and when it reaches 100 °C, it can be sterilized if it lasts for a period of time.

In the end, high temperatures can kill viruses.
A virus is a special organism that does not have a cellular structure. Their structure is very simple and consists of a protein shell and the genetic material inside. High temperatures can destroy the protein molecules of the virus, killing them.
Viruses cannot survive on their own, they must live in the cells of other organisms, and once they leave the living cells, they do not show any signs of life activity.
High temperatures can kill viruses because they denature the virus's protein capsid and lose its protective effect on the genetic material it envelopes and protects.

OK. A virus is a non-cellular life form, it is composed of a long nucleic acid chain and a protein coat, and the virus has no metabolic mechanism of its own, no enzyme system.
As a result, when the virus leaves the host cell, it becomes a chemical substance that has no life activity and cannot reproduce on its own. Once in the host cell, it can use the matter and energy in the cell, as well as the ability to replicate, transcribe, and translate, to produce a new generation of viruses like it based on the genetic information contained in its own nucleic acids.

Heating and high-temperature sterilization is still the most important and effective method of food sterilization at present. In response to the new coronavirus pneumonia, experts also pointed out that the virus does not have high temperature resistance, and it can be killed in 30 minutes when heated to 56 degrees outside the body. So, what is the principle of high temperature to kill viruses?
The principle that high temperature can kill viruses is mainly based on two aspects:
The first aspect is because of protein denaturation. Most viruses are mainly composed of proteins, and high temperature can irreversibly denature the proteins that make up living organisms, inactivating enzymes, causing irreversible damage to the fine cell structure of living organisms, loss of life function, and natural death of viruses.
The second reason is that high temperature will change the volume of fluid in the cell, which will break down the cell, causing the DNA of the genetic material to break down at high temperature, causing the death of the virus.
-
High temperature can denature the proteins in the organism, and proteins are the main bearers of life activities, so viruses and bacteria can be killed in high temperatures.
-
High temperature can kill bacteria or viruses, and most bacteria will die after boiling at 100 degrees Celsius for 10 minutes, except for a few heat-resistant bacteria or spores that can still survive.
The principle of high-temperature sterilization is mainly based on two aspects:
1. It is protein denaturation, high temperature can irreversibly denature the proteins that make up the living body, inactivate the enzymes, cause irreversible damage to the cell structure of the living body, loss of life function, and then die;
2. The main reason is that high temperature will change the volume of fluid in the cell, thereby breaking the cell. The last reason is that the genetic material DNA can also break down at high temperatures, causing bacteria to die.
To practice yoga in winter, don't rush to start asana practice, be sure to fully move your joints and warm up, otherwise it is easy to get injured; The practice of asanas should also be from simple to difficult; It is also important to meditate on the breath before the practice to prepare the mind and body to begin the practice of yoga; Rest after practice is also very necessary, do not ignore it in order to save time, rest is not only to restore the body's strength, but also to allow the energy to gather and save in the body, so that it is not wasted. >>>More

Under the premise that there is no open flame, 75 degree alcohol wipes will not catch fire during daily use; The spontaneous combustion temperature of alcohol is 323 degrees Celsius, and it will spontaneously ignite above 323 degrees Celsius. When using alcohol for disinfection in daily life, you need to pay special attention to the instructions for use and specific operation methods, do not use it near the fire source, and leave the room in time after spraying alcohol in a confined space.
Generally, the material temperature exceeds 35 degrees. It is easy to burn bacteria.
The enamel pot should not be used for stir-frying, because the enamel tableware coated on the outer layer of the enamel products is actually a layer of enamel, containing aluminum silicate and other substances, due to the collision and friction of stir-frying, it is easy to cause damage, so that aluminum silicate and other substances will be transferred to the food. In addition, in order to prolong the life of the pot, it is best not to rush to the heat and cold, and try not to store acidic foods such as vinegar and kimchi for a long time. When buying an enamel pot, it is best not to have a bright color, such as red, orange will contain cadmium and other metals, which is not good for the human body. >>>More
