Metabolite Identification
Common NameL-Thymidine
DescriptionThymine 2-desoxyriboside belongs to the class of organic compounds known as pyrimidine 2'-deoxyribonucleosides. Pyrimidine 2'-deoxyribonucleosides are compounds consisting of a pyrimidine linked to a ribose which lacks a hydroxyl group at position 2. Thymine 2-desoxyriboside is an extremely weak basic (essentially neutral) compound (based on its pKa). In humans, thymine 2-desoxyriboside is involved in the metabolic disorder called the beta-ureidopropionase deficiency pathway. Outside of the human body, Thymine 2-desoxyriboside has been detected, but not quantified in, a few different foods, such as green beans, pulses, and yellow wax beans. This could make thymine 2-desoxyriboside a potential biomarker for the consumption of these foods. This compound has been identified in human blood as reported by (PMID: 31557052 ). L-thymidine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically L-Thymidine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
