Science Buddies: "Ask an Expert"

Hello.

I have a question for my science fair project (about Vitamin C levels over time and effects of temperature on Vitamin C). My Question is (for the background research) what exactly happens when Vitamin C is in contact with oxygen and goes through a process called oxidation (does it lose electrons, or something else?) and how do these changes (from being oxidized) affect the properties of Vitamin C.

Thanks for your help!
