This was amazingly helpful. I am writing an assignment on oxidative stress and oxidative damage, he broke things down in a way that i can now start to understand it all. Made my day!
You are so amazing! I'm studying for my masters final and not only were you able to explain, you were able to deliver me the motivation I needed to go through this. THANK YOU X10000 + all antioxidants in the world :) Keep up the amazing work! You are amazing at your job!
This was amazing. I'd been struggling with this and listening to my prof's lecture video over and over and it never made sense. I clicked on your video not intending to listen to the whole 78 minute lecture but in the end I did because you explained everything so clearly and easy to understand. THANK YOU!!!
this is the best video i have ever watched . better then even the UCI open courseware. it not only cleared up my biology knowledge, but also cleared up my chem basics. being a chem student , i totally loved it.
Thank you very much for this lecture, I was looking to "refresh" my knowledge about this topic, it would help me a lot for my thesis defense. Greetings form Mexico!!
I am a Ph.D scholar at Indian Institute of Technology, KHARAGPUR and my topic is cancer biology. Though I am a Bachelor of Pharmacy, I always hate chemistry. But after watching your lecture, now I am loving it. 😁
That's a very good and extensive explanation of this topic. Thanks for making it easy to understand. Recently I found out there's a test that checks the quantity of antioxidants in one's own saliva. It's called Lelolab. Have you ever heard of it?
One of the excellent lectures I have ever had! I really had hard time understanding lipid oxidation in foods because of the less chemistry background! This cleared all my basic concepts. The only doubt I have is Why Hydroxide radical is mentioned as Ho.? Why is it not o2 (-3) after adding one electron to peroxide ?
Superb! Antioxidants are the chemical compounds which protect our body from the molecules known as free radicals which are produced as a bi-product during metabolic processes in our body. I recently came across an informative write up (Top 20 Antioxidant-Rich Foods) at zovon.
41:00 This causes the electrical charge to escape through the cell membrane. The membrane potential in neurons is closer to the threshold. This will increase excitatory sensitivity, resulting in excessive thinking that can cause depression. (thoughts in the head are too aggressive). In addition, it may cause epilepsy seizure (oscillating action potential through the neural network) , migraine attacks, abnormal neuronal network noise, and reduced brain efficiency (fatigue, IQ decline, alcoholism, junk food, etc.).
He was speaking with respect to molecular orbital theory. So i don't think there's existence of pi-bond. For that we have to go back to atomic orbitals participation in bonds.
Why does oxygen biradical have two unpaired electrons with necessarily the _same_ spin? Shouldn't there be like a 50/50 chance of having the same spin vs. opposite spin? -Or does an external field align all unpaired electrons preferentially in one direction?- edit: Hund's rule, apparently. Complicated QM reasons.
