Ascorbic acid synthesis in certain guinea pigs.

The course of healing subsequent to experimental trauma in one of these animals proved to be entirely normal and vitamin C concentration in its liver after 8 months of a scorbutogenic regimen was found to be more than twice that in guinea pigs with a daily intake of 10 mg ascorbic acid. It is evident that certain guinea pigs are capable to synthesize ascorbic acid that fully covers the needs of the organism. However, the freqency of occurence of such guinea pigs appears to be extremely small.
