The immune system may kick in when animals eat, releasing reactive oxygen molecules to kill microbes on food, helping to protect from disease.

It has been theorized that the major cause of bleaching is the result of chloroplast damage due to heat stress, which results in the production of toxic, highly reactive oxygen molecules during photosynthesis.

The cause of the damage is still poorly understood, but radiation is known to create highly reactive oxygen - containing molecules in the body.

In a third study published online by Science on 6 April (www.sciencexpress.org), molecular geneticist Valter Longo of the University of Southern California in Los Angeles and colleagues battered a population of yeast mutants with heat or paraquat, a chemical that creates reactive oxygen moleculeIn a third study published online by Science on 6 April (www.sciencexpress.org), molecular geneticist Valter Longo of the University of Southern California in Los Angeles and colleagues battered a population of yeast mutants with heat or paraquat, a chemical that creates reactive oxygen moleculein Los Angeles and colleagues battered a population of yeast mutants with heat or paraquat, a chemical that creates reactive oxygen molecules.

While reactive oxygen species (ROS), can damage and kill cells — these molecules have also been implicated in normal biochemical processes.

In this case, they form naturally as ozone — a high - energy oxygen molecule — reacts with carbon chains that have double bonds, forming a compound that has two reactive pairs of electrons.

Physiologist Dino Giussani and colleagues at the University of Cambridge in the United Kingdom theorized that hypoxia promotes harm in the womb primarily through stress caused when the low level of oxygen creates an overload of highly reactive molecules known as free radicals.

Increased glucose processing has long been thought to inflict damage on the mitochondria (the cell's power generators), which then produce large amounts of reactive oxygen molecules, which in turn leads to kidney disease.

STEVEN BENNER: Radiation causes damage to DNA by way of specific molecules, in particular, reactive oxygen species.

Reactive oxygen species (ROS) are important molecules inall cells, but in high concentrations cause frequent mutations.

Research suggests that Vitamin C is a highly effective antioxidant and that small amounts can protect essential molecules in the body from free radical damage and reactive oxygen species generated during normal metabolism, as well as through exposure to toxins and pollutants.

Energy metabolism and the production of Reactive Oxygen Species (very small molecules that can result in significant damage to cell structures, of which include oxygen ions, free radicals and peroxides) are thought to underpin many nuerodegenerative disorders, and creatine is thought to enhance the brains ability to survive the metabolic and physical trauma associated with these condiOxygen Species (very small molecules that can result in significant damage to cell structures, of which include oxygen ions, free radicals and peroxides) are thought to underpin many nuerodegenerative disorders, and creatine is thought to enhance the brains ability to survive the metabolic and physical trauma associated with these condioxygen ions, free radicals and peroxides) are thought to underpin many nuerodegenerative disorders, and creatine is thought to enhance the brains ability to survive the metabolic and physical trauma associated with these conditions.

In the human body, oxygen inevitably generates reactive molecules throughout all the tissues of the body called free radicals.

The mitochondria in our cells are responsible for releasing energy from the molecules in our food, but they also unleash electron - stealing free radicals like reactive oxygen and reactive nitrogen species.

Global warming is implicated in the loss of Arctic ozone because greenhouse gases trap energy lower down, heating up the atmosphere nearer the ground but cooling the stratosphere, creating conditions conducive to the formation of the reactive chemicals that break apart the three - oxygen molecules of ozone.
