"Wrinkles of Time" a project about redox in aging
Transcript of "Wrinkles of Time" a project about redox in aging
Super-oxide is even more desperate than oxygen to become stable. It wants electrons very badly! What is the role of the electron in this reaction?
The role of the electrons in this reaction is the same role as in every redox reaction. The electrons were shared by both oxygen and hydrogen and since they are molecular, the electrons shifted toward oxygen without completely abandoning hydrogen. How are oxidation reactions involved in skin aging? When metabolism occurs in the body, super-oxide is formed. super-oxide + super-oxide +
hydrogen = hydrogen peroxide
O2^0 + O2^0 + 4H^0 = 2H2^+O2^-2
Oxidation 4H^0 --> 4H^+ + 4e-
Reduction4O^0 + 4e^- --> 4O-2 Before we start, here's what you should know: *Oxygen has 2 valence electrons
*Super-oxide is what oxygen is called when it has gained only 1 electron (it is very reactive) Not to alarm you, but every oxygen-filled breath we take deteriorates our carbon-based bodies. (FYI) :O Eat your fruits and vegetables! They contain vital anti-oxidants that may not stop aging, but hey, it might stall those crow-feet from coming in early ;) The properties and uses of materials are determined by the atoms that are bonded together to create them and how they are bonded.
You certainly don't want the same materials that go into
making your anti-aging cream to be the same that went into building
your house. " Which is better? To be young and wise, or old and young at heart? I'd rather like to think that at no point in our lives do we stop enjoying life and that by enjoying it, we grow all the more wiser. Is a story not the more interesting if there is more to tell? When I get older, instead of spending money trying to look younger, I'd rather spend my time telling about how God has blessed the many years of my life." -Emily Ploetz
