Observations on Bound Ascorbic Acid in Guinea Pig Liver.

Abstract
Studies with C14 labeled L-ascorbic acid have yielded further evidence for the presence of a bound form of the vitamin in guinea pig liver. About 19% of the liver L-ascorbic acid is bound in normal and 28% in vit. C deficient animals. When D-ascorbic acid, the enantiomorph of L-ascorbic acid, is administered to vit. C-deficient guinea pigs, it was found in a bound form to about the same extent as L-ascorbic acid.
