Description_x000D_ General description_x000D_ Thymine is one of the four nucleobases, along with adenine, guanine and cytosine found in deoxyribonucleic acids (DNA)._x000D_ Application_x000D_ Thymine has been used as a standard nitrogenous base in high-performance liquid chromatography-ultraviolet (HPLC-UV) for the quantification of bone DNA samples, Raman scattering experiments. It has also been used as supplement in C2C12 myoblast cells._x000D_ Packaging_x000D_ 5, 10, 25, 100 g in poly bottle_x000D_ Biochem/physiol Actions_x000D_ Thymine used in studying DNA structure byirradtaion methods leading to cross-linking reactions and derivitizations. Thymine dimers are indicative of DNA damage. Thymine is used with metal (mercury) to form thymine−HgII−thymine (T−HgII−T) duplexes. Thymine starvation in bacteria leads to halt in DNA synthesis and is referred as thymine-less death.
