Cytosine monohydrate
WebThe distances and angles of the cytosine moiety of the molecule do not compare well with those found in cytosine monohydrate and cytidine. The discrepancies are attributed to the influence of hydrogen bonding on the double bond character of the carbonyl bond C*(2)-O*(2) and on the influence of the N 4 a axis which are held together by van der ... WebJun 1, 2016 · Cytosine is one of the pyrimidine derivatives which consists of heterocyclic compound along with aromatic amine and keto groups [2], [3]. Cytosine plays an important role in DNA/RNA base pairing, through several hydrogen-bonding patterns and controls the essential features of life as it is involved in genetic codon of 17 amino acids [4].
