Under Nutritional Markers you will find Thymine. Thynine is a nucleotide.

Here is what the commentary has to say:

“Thymine is involved in the metabolic disorder called the beta-ureidopropionase deficiency pathway. Thymine has been found in several different foods, such as mammee apples, nances, angelica, rocket salad (ssp.), and common chokecherries. This could make thymine a potential biomarker for the consumption of these foods. Thymine is a potentially toxic compound. Thymine has been found to be associated with several diseases such as temporomandibular joint disorder, colorectal cancer, and thymidine treatment; thymine has also been linked to several inborn metabolic disorders including dihydropyrimidine dehydrogenase deficiency and beta-ureidopropionase deficiency.”

And while all of this is true, it is not a commentary about the nutritional aspects of Thymine.

In the context of Nutritional Markers, elevated thymine is an indication of B6 deficiency of inefficiency.
