What are the free radicals in the body, what are the free radicals in the human body

Free radicals are the killer of living cells, which refers to an atom or a molecule composed of a group of atoms, which becomes an unpaired extremely unstable molecule due to the loss of electrons. Free radicals are active electrons that can attack the cell membranes, subcellular structures, nucleic acids, and proteins of various organs with blood circulation, causing damage to target cells and leading to a series of unknown diseases. Free radicals can cause many diseases, so scavenging free radicals is the fundamental method to prevent and treat many diseases.

Human free radicals, also known as "free radicals" in chemistry, refer to atoms or groups with unpaired electrons formed by the covalent bonds of the molecules of compounds under external conditions such as light and heat. When a covalent bond is unevenly cracked, the shared electron pairs between the two atoms are completely transferred to one of the atoms, and the result is the formation of positively charged and negatively charged ionic sons, which is called heterocleavage of the bond.

When writing, it is common to add a "·" next to the atomic symbol or atomic cluster symbol. Indicates the presence of unpaired electrons. Such as hydrogen radical (H·, that is, hydrogen atom), chlorine radical (Cl·, that is, chlorine atom), methyl radical (CH3·). Free radical reactions play an important role in combustion, gas chemistry, polymerization, plasma chemistry, biochemistry, and a variety of other chemical disciplines.

Human free radicals refer to atoms or groups with unpaired electrons formed by the homogenous cleavage of covalent bonds of the molecules of compounds under external conditions such as light and heat. Free radical reactions play an important role in combustion, gas chemistry, polymerization, plasma chemistry, biochemistry, and various other chemical disciplines. The first free radical to be discovered and confirmed in history was the triphenyl radical discovered by Moses Gonberg at the University of Michigan in 1900.

In general, life is inseparable from free radical activity. Our body moves from the inside out all the time, burning energy every moment, and the porters responsible for transmitting energy are free radicals. When these free radicals that help in energy conversion are trapped in cells and cannot run around, they are harmless to life.

But if the activity of free radicals gets out of control and exceeds a certain amount, the normal order of life will be disrupted, and diseases may follow.

Summary. Free radicals, also known as "free radicals" in chemistry, refer to atoms or groups with unpaired electrons formed by the homogenization of covalent bonds of the molecules of a compound under external conditions such as photothermal and other conditions. (In the case of uneven cleavage of a covalent bond, the shared electron pairs between the two atoms are completely transferred to one of the atoms, resulting in the formation of positively and negatively charged ions, a method of breaking known as anisocleavage of the bond.)

Free radicals are exclusively inducers produced in the body and are by-products of normal metabolism.

Free radicals, also known as "free radicals" in chemistry, refer to the molecules of compounds under external conditions such as photothermal and covalent bonds to form atoms or groups with unclear imitation pairs. (When a covalent bond is inhomogeneously cracked, the shared electron pairs between the two atoms are completely transferred to one of the atoms, and the result is that the polar bands become positively charged and negatively charged, a method of cleavage called anisocleavage.) ）
