Poisons are highly reactive and unstable molecules that are produced in your body naturally as a byproduct of metabolism (oxidation), or by experience of toxins from the environment such as tobacco smoke and ultraviolet light. Poisons have a lifespan of only a fraction of a second, but during that time damages DNA, sometimes creating the mutations that will cause cancer. Antioxidants from the foods we eat can neutralize the unstable molecules, decreasing the probability of damage.
We are going to look at the structure, causes, and effects of toxins, and also what you need to know about antioxidant supplements if you have cancer.
Definition and Structure of Free Radicals
Free-radicals are atoms that includes an unpaired electron. Because of this deficiency of a reliable variety of housing electrons, they are in the constant search to bind with another electron to stabilize themselves-a process that could cause harm to DNA as well as other elements of human cells. This damage be involved from the continuing development of cancer as well as other diseases and accelerate the aging process.
Forms of Poisons
There are several types of poisons, though, in humans, the main are oxygen toxins (reactive oxygen species). Examples include singlet oxygen (when oxygen is "split" into single atoms with unpaired electrons), peroxide, superoxides, and hydroxyl anions.
Causes/Sources of Free-radicals
You may wonder where free-radicals are derived from to start with. Toxins can be achieved in a few different ways. They could be generated from normal metabolic processes within the body, or by exposure to carcinogens (cancer causing substances) from the environment.
Free radicals can be done both by carcinogens and the normal metabolic processes of cells.
Free-radicals As a result of Normal Metabolic Processes
Our body often produces toxins in the process of extracting nutrients to produce the energy which allows our bodies to function. The production of free-radicals in normal metabolic processes like this is among the reasons how the likelihood of cancer increases as we grow old, even though everyone has few exposures to cancer-causing substances.
Toxins Due to Experience of Carcinogens
Experience carcinogens inside our environment can also produce free radicals. Types of some carcinogens include:
Radon in the home
Environmental and occupational substances and chemicals like asbestos and vinyl chloride
How Free Radicals Might cause Cancer
Damage carried out to genes from the DNA may lead to genes that leave ineffective proteins; proteins should be watchkeepers in the cells of the body. A few of these mutations may involve genes identified as tumor suppressor genes. These genes code for proteins that function to correct damages in DNA or cause cells which might be damaged beyond salvage to be removed via a procedure for apoptosis (programmed cell death).
Oncogenes are genes that code for proteins that promote the growth of cells. Normal genes by the body processes called "protooncogenes" are very important to promote the increase of an baby while pregnant and transiently produce proteins that assist in tissue repair. Mutations over these genes (that happen to be then oncogenes) resulted in continuous production of proteins that promote the development of an cell.
Most often, it is a compilation of mutations in the tumor suppressor genes and oncogenes leading to cancer. Damage (mutations) to tumor suppressor genes allows a broken cell to thrive unrepaired (abnormal) and damaged oncogenes promote the development of that damaged cell. The actual result is-the formation of your cancer cell.
