What are free radicals? Well, in the body, free radicals typically take the form of reactive oxygen species, which include peroxides, superoxide, and the hydroxyl radical. Find more videos at http://osms.it/more.

I hope there is anyone who will answer me.
I just didn't get why is it pointed with bullet mark and not just anion of an element, if atom or molecule gets one e- it becomes anion so why is this called radical. Please don't be mad with me if I'm wrong but I have been so confused so please help me find a difference.
That's the plan! Thanks for the kind words, Andrea! Did you know that if you like & review us on Facebook then you’ll get access to our videos a day before they’re published on YouTube? Check it out here: http://bit.ly/2u35D6J

he would technically mean, hyrdogen atom, one proton, one electron. a hydrogen ion would just be a proton, and no electron. For oxidative phosphorylation, a hydrogen ion comes from outside the mitochondrial matrix and the electron is donated, which pulls the hydrogen ion through the cell wall, to make H2O. please correct if wrong. Thanks
the hydrogen ion is positive, the oxygen gets reduced (gains electron, makes the oxygen more negative) positive and negative attractive forces are at play. and hydrogen follows the rules and bonds to complete rule chemistry.
Osmosis. You could find this in many papers and textbooks. For instance, Lippincott 6th ed. (p. 520), Marks' 4th ed. (p. 448) and Harpers (2012, p.225). I hope it helps and thank you for your great work.
Thanks for posting this. I came here specifically to ask about that, since I read elsewhere that “unlike superoxide, which can be detoxified by superoxide dismutase, the hydroxyl radical cannot be eliminated by an enzymatic reaction.”
Hello - a wonderful video, thank you. I have a question - you mention that glutathione peroxidase works on the hydroxyl radical. This seems to be different to what it says in at least some other textbooks. Is this a new discovery? Are you able to shine any light on this difference of opinion? Thank you.
In normal conditions, Vitamin E,A,C deals with that because they can donate e- , but in pathological conditions where like in ischemia, the cells are devoid of nutrients and O2, which when prolonged depending on the type of tissue cells will lead to irreversible injury .
