Help with chemistry?

[Guest guest]

I'm feeling very frustrated by not understanding some basic chemistry

-- the latest example is that I'm trying to replace vit C to comply

with the Low Oxalate Diet, and seeing supps that say " vit C as calcium

ascorbate " . OK, so WTH does that mean? Does it act like calcium or

like vit C, or some combination?

My question really is whether anyone knows of a good book or other

resource to learn this stuff.
