An atom ormoleculewith an unpairedelectron. Because they have a freeelectron, suchmoleculesare highly reactive. Examples Singletoxygen, molecules with a free hydroxy group (-OH) Properties Free radicals are capable of starting rapid chain-reactions that destabilize the ions in other nearby molecules ...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
What is Salvage Chemotherapy? Discussion Comments Byanon1005569— On Sep 26, 2021 I just had a radical hysterectomy: ovaries, tubes cervix, uterus. I had 3 cancer cells diagnosed in my left tube. They tell me there's a possibility of endocrine cancer! Will I have to have chemotherapy?
What is radical environmentalism?Environmentalism:Environmentalism had its origins in the nineteenth century. This movement grew during the twentieth century because of increasing pollution, deforestation, and the extinction of a number of plant and animal species....
Oxidation consists of chemical reactions that damage our cells. That’s where antioxidants come in. Normally, our body can fight off this stress through its own antioxidant defenses. But when the antioxidant-producing capacity is overwhelmed by too many free radicals, damage can occur as our body...
What is Chemical Reaction Kinetics? Chemical reaction kinetics provide a quantitative or qualitative measurement of the rate(s) of reactions and provide insight into the dependence of these rates on variables such as concentration, temperature, pressure, the presence of catalysts, the physical state of...
Out in the world, this is a normal process, but in the body, it can result in unnecessary and unwanted damage. Free radicals are "free" because they float around until they stabilize, and "radical" in the sense that there are a wide variety of molecules from which they can take an ...
Oxidation is the process of free radical damage caused by radical oxygen. Antioxidants are molecules that can safely donate electrons to free radicals, terminating the oxidative chain reaction before critical molecules are damaged. Although several enzyme systems in the body scavenge free radicals, the...
