Chemical Information

FooDB Name

Cytosine

Description

Cytosine, also known as C, belongs to the class of organic compounds known as pyrimidones. Pyrimidones are compounds that contain a pyrimidine ring, which bears a ketone. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. Cytosine is an extremely weak basic (essentially neutral) compound (based on its pKa). Cytosine exists in all living species, ranging from bacteria to humans. Cytosine has been detected, but not quantified in, several different foods, such as oil-seed camellia, nectarines, rowals, sesbania flowers, and nutmegs. This could make cytosine a potential biomarker for the consumption of these foods.
