Guanine structural formula

Chemical Name 2-Amino-1,9-dihvdro-9-[(2-hvdroxvethoxv)methvl] -6H-purin-6-one Common Name Acycloguanosine 9-(2-hvdroxvethoxvmethvl)guanine Structural Formula ... [Pg.27]

Common Name Acycloguanosine 9-(2-Hydroxyethoxymethyl)guanine Structural Formula ... [Pg.94]

The three pyrimidine bases are uracil, thymine, and cytosine, usually abbreviated U, T, and C. Adenine (A) and guanine (G) are the two purine bases. Adenine, guanine, and cytosine are found in both DNA and RNA, but uracil is ordinarily found only in RNA, and thymine only in DNA. Structural formulas of the five bases are given in I Figure 11.3. [Pg.351]

Section 17.81). This is the form normally present in DNA, and, as we have seen, it pairs specifically with cytosine. If guanine tautomerizes (see Section 18.2) to the lactim form, it pairs with thymine instead. Write structural formulas showing the hydrogen bonds in this abnormal base pair. [Pg.1120]

Draw a structural formula for the /3-A/-glycoside formed between (a) D-ribofuranose and thymine and (b) D-ribofuranose and guanine. Label the anomeric carbon and the AZ-glycosidic bond. (See Example 17.5)... [Pg.611]

Five organic bases (amines) are most often found in nucleotides. The bases are adenine, guanine, cytosine, uracil, and thymine. They link to the sugars through the indicated nitrogen (in color) in each of the following structural formulas ... [Pg.1052]

After further spontaneous rearrangements, hydroxylamine derivatives produce electrophilic intermediates, which are able to modify DNA bases (Sugimura and Sato, 1983). One of the possible structures of DNA adducts formed by Trp-P-2 with guanine is given in Formula 14.7. [Pg.313]

The nitrogen bases found in DNA comprise the two purines adenine and guanine and the two pyrimidines thymine and cytosine in the formulas shown in Figure 15-20 the asterisk indicates the hydrogen atom that is replaced by the carbon atom of the sugar ring in DNA, and the double bonds correspond to only one of the several valence-bond structures for each molecule. The molecules are planar, because each of the bonds in the purine and pyrimidine rings has some double-bond character. [Pg.523]
