Flurouracil is a drug that is similar in structure to the pyrimidine uracil. It is usually used to treat a specific type of skin cancer called superficial basal cell carcinoma and other skin ailments, including scaly or crusted lesions caused by too much sun exposure. The drug is usually sold...
A diet high in pyrimidine sources is less likely to contribute to gout. 12 Purine Involved in energy transfer within cells. ATP, a key energy molecule, is a purine nucleotide. 7 Pyrimidines A type of organic compound with a single-ringed structure. Cytosine, thymine, and uracil are pyrimidin...
Thymine (T):Thymine is a pyrimidine with the chemical compound C5H6N2O2. A thymine-based nucleotide is called athymidine. Thymine is a fused ring with conjugated bonds. Thymine bonds with adenine to form nucleic acid; this helps stabilize the nucleic acid structures. Uracil (U):Uracil is a...

Purine and Pyrimidine Pairing DNA is double-stranded, and when split into two parts is used to make RNA. In double-stranded DNA, which looks like a ladder when "unwound," adenine (A) pairs with thymine (T) while cytosine (C) pairs with guanine (G). In RNA, uracil (U) takes the ...
In DNA, the purine-pyrimidine bonds are hydrogen bonds. In some instances, this is a hydrogen bonded to an oxygen, and in others it is a hydrogen bonded to a nitrogen. The C-G complex includes two H-N bonds and one H-O bond, and the A-T complex includes one H-N bond and one ...
