However, I think it's best if they're separate entries; ascorbic acid about the general class of ascorbic acid, Vitamin C about the L-idoslkwhater of ascorbic acid.
Exactly. isomer. The L isomer. Althought that isn't the only nomenclature that can be used to describe the isomeric differences. I'm not an expert on the biochemistry of ascorbic acid--it could be that the L form and the D form interconvert to form a racemate in vivo, but I wouldn't bet on it.
one can discuss ascorbic acid as a organic acid without any reference to it as a nutrient. That's why I originally put the stuff in about it's use as a reductant in chemical developer solutions--[Eastman Kodak]? uses tons of this stuff!
