Cytosine is one of the four main bases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA). Cytosine reagent is used in a wide variety of research applications, as an enzyme substrate or precursor of effector molecules such as cytosine sugars. Cytosine serves as useful in the examination of protein, enzyme, and other molecule structure and function.
