Full Answer

What does oxidation do to your body?

We could go on and on…So, let’s discuss oxidation. Oxidation in the body creates a byproduct called reactive oxygen species (ROS) that could function as free radicals or eventually produce free radicals. This is actually a very natural process. ROS in immune cells can help combat invading pathogens such as viruses, bacteria, and fungi.

What does oxidation have the ability to do?

Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction. When oxidation occurs, the oxidation state of the chemical species increases. Oxidation doesn't necessarily involve oxygen! Originally, the term was used when oxygen caused electron loss in a reaction. The modern definition is more general.

How long does it take for a body to decompose?

It really depends on the cause of the death. Typically placed 6ft down, without a coffin, in ordinary soil, eight to twelve years to completely decompose into a skeleton. Now if placed in a coffin, it may take many more years, depending on the type of wood used for the coffin. For example, solid Oak will slow down the process. It is believe that one man's process of decomposing took 50 years in an Oak coffin. What also you have to consider is decomposition in the air is twice as fast as when the body is underwater and four times as fast as underground. A corpse left above ground is rapidly bro

What happens when a free radical reacts with another molecule?

When a free radical reacts with other molecules, the process is known as oxidation . When oxidation occurs, the unpaired electron combines with another molecule. Free radicals are generally a by-product of energy production in the body. Similarly, certain substances, such as ozone, cigarette and cannabis smoke, can increase free radicals in the body.

Why is it important to maintain a healthy weight?

A study conducted in 2015 revealed that maintaining a healthy weight may also be vital to preventing oxidative stress. Excess fat cells are known to produce inflammatory substances that can prompt the production of free radicals by the immune system.

Oxidation and Reduction Reactions in the Body

Oxidation describes chemical reactions where electrons are lost, whereas reduction refers to reactions where electrons are gained. Electrons are stable atomic particles that are negatively charged, and the transfer of electrons between molecules produces energy. Electrons do not exist by themselves; they are always associated with an atom.

Oxidative Metabolism: Cellular Respiration

Food is converted to usable energy through metabolic processes in the cells of the body. Metabolism is defined as the sum of chemical reactions that occur within each cell to supply energy for important reactions and processes.

Cellular Oxidation in the Body

During oxidative metabolism, or cellular respiration, food molecules are oxidized to produce energy in the form of ATP.

What is slow oxidizer?

A slow oxidizer releases energy too slowly to maintain adequate health. This is analogous to a wood stove whose fire is too small to heat the room. To improve his health status and energy level, his metabolic furnace, i.e., oxidation rate, must be increased. The slow oxidizer has ex­hausted thyroid and adrenal glands. These major energy producing glands must be stimulated through proper diet and supplements to restore them to normal function.

Is a mixed oxidizer fast or slow?

A mixed oxidizer has an erratic metabolism. Sometimes it is too fast, other times it is too slow. The mixed oxidizer, to achieve a higher energy level, must stabilize his oxidation rate. The mixed oxidizer's adrenal and thyroid gland are out of synchronization, that is, the thyroid gland may be overactive and the adrenal glands underactive, or vice versa. The dietary and sup­plemental requirements are balanced between the fast and slow oxidizer.

Rust is from oxidation of the iron. But oxidation doesn’t mean aging for people

Why is my hair gray?

A white cell uses oxidation to kill harmful bacteria. The gray hair so many color– it is gray because of the “bleaching” effect of anti-oxidants.

Why do we oxidize hair?

You want your body to oxidize some things (my hair, now the true platinum color) – you want to kill invading bacteria, cells that go wild (unlike the teenage daughter who wants to go to Mexico for spring break – although oxidizing the boys in Mexico might be a good thing).

Do you need oxidants to wash clothes?

Ok – yes, you need the oxidants to wash your clothes. Nothing like some oxy-clean to whiten the stains. But, the body uses oxidation in a variety of ways that are useful.

Does oxidation cause heart disease?

There is a theory that the stress of oxidation leads to many diseases including heart disease, cancer, and even aging. As a result, there has been a rush of studies examining the role of anti-oxidants and to see if diets rich in anti-oxidants will show a decrease in those disease.

Can oxidation harm us?

We have a balance in our bodies– those things that can help us- oxidation against bacteria and cancer – -can harm us if it runs wild. Just like our immune system can turn against us.

Which compounds can acquire a prooxidant behavior?

6.2. Polyphenols. Under conditions like high concentrations, high pH, and the presence of redox-active metals, phenolic compounds can acquire a prooxidant behavior [157, 158], mainly based on the generation of an aroxyl radical or a labile complex with a metal cation exerting redox activity.

What are the causes of free radicals?

Free radicals are generated from both endogenous and exogenous sources. Immune cell activation, inflammation, ischemia, infection, cancer, excessive exercise, mental stress, and aging are all responsible for endogenous free radical production. Exogenous free radical production can occur as a result from exposure to environmental pollutants, heavy metals (Cd, Hg, Pb, Fe, and As), certain drugs (cyclosporine, tacrolimus, gentamycin, and bleomycin), chemical solvents, cooking (smoked meat, used oil, and fat), cigarette smoke, alcohol, and radiations [15–25]. When these exogenous compounds penetrate the body, they are degraded or metabolized, and free radicals are generated as by-products.

What is H2O2(a nonradical)?

H2O2(a nonradical) is produced by multiple oxidase enzymes, that is, amino acid oxidase and xanthine oxidase.

What are the two types of reactions that produce ROS?

ROS production basically relies on enzymatic and nonenzymatic reactions. Enzymatic reactions able to generate ROS are those involved in respiratory chain, prostaglandin synthesis, phagocytosis, and cytochrome P450 system [10–20]. Superoxide radical (O2•−) is generated by NADPH oxidase, xanthine oxidase, and peroxidases. Once formed, it is involved in several reactions that in turn generate hydrogen peroxide, hydroxyl radical (OH•), peroxynitrite (ONOO−), hypochlorous acid (HOCl), and so on. H2O2(a nonradical) is produced by multiple oxidase enzymes, that is, amino acid oxidase and xanthine oxidase. Hydroxyl radical (OH•), the most reactive among all the free radical species in vivo, is generated by reaction of O2•−with H2O2, with Fe2+or Cu+as a reaction catalyst (Fenton reaction) [12–19]. Nitric oxide radical (NO•), which plays some important physiological roles, is synthesized from arginine-to-citrulline oxidation by nitric oxide synthase (NOS) [12–19].

How is cancer driven?

Cancer can be driven and/or promoted by chromosomal abnormalities and oncogene activation determined by oxidative stress. Hydrolyzed DNA bases are common by-products of DNA oxidation and are considered one of the most relevant events in chemical carcinogenesis [14, 22].

What are the reactive oxygen species?

Superoxide radicals (O2•−), hydrogen peroxide (H2O2), hydroxyl radicals (•OH), and singlet oxygen (1O2) are commonly defined reactive oxygen species (ROS); they are generated as metabolic by-products by biological systems [1, 2]. Processes, like protein phosphorylation, activation of several transcriptional factors, apoptosis, immunity, and differentiation, are all dependent on a proper ROS production and presence inside cells that need to be kept at a low level [3]. When ROS production increases, they start showing harmful effects on important cellular structures like proteins, lipids, and nucleic acids [4]. A large body of evidences shows that oxidative stress can be responsible, with different degrees of importance, in the onset and/or progression of several diseases (i.e., cancer, diabetes, metabolic disorders, atherosclerosis, and cardiovascular diseases) [5].

How does oxidative stress affect cancer?

Cancer onset in humans is a complex process, which requires both cellular and molecular alterations mediated by endogenous and/or exogenous triggers. It is already well known that oxidative DNA damage is one of those stimuli responsible for cancer development [14, 15, 22]. Cancer can be driven and/or promoted by chromosomal abnormalities and oncogene activation determined by oxidative stress. Hydrolyzed DNA bases are common by-products of DNA oxidation and are considered one of the most relevant events in chemical carcinogenesis [14, 22]. The formation of such kind of adducts impairs normal cell growth by altering the physiological transcriptomic profile and causing gene mutations. Oxidative stress can also cause a variegated amount of modifications against DNA structure, for example, base and sugar lesions, DNA-protein cross-links, strand breaks, and base-free sites. For instance, tobacco smoking, environmental pollutants, and chronic inflammation are sources of oxidative DNA damage that could contribute to tumor onset [14, 17, 29]. Oxidative stress resulting from lifestyle reasons can also play an important role in cancer development, as suggested by the strong correlation between dietary fat consumption (a factor that exposes the organism at greater risk of lipid peroxidation) and death rates from different types of cancer [16, 21].
