The nature of the chemical shift tensor is a potential source of complications in relaxation studies. For sugar carbons, the CSAs are around 40 ppm and their contribution to relaxation of protonated carbons is nearly negligible. On the other hand, CSA values of the protonated carbons of the bases are between 120 and 180 ppm, the tensors deviate quite significantly from axial symmetry and none of their principal components is colli-near with the C-H bond. This makes interpretation of the relaxation rates in terms of molecular dynamics prohibitively complicated or, if neglected, introduces an error whose magnitude has not yet been evaluated. 

After preparing niobic acid by Marignac s method, he mixed eighty-two parts of it with eighteen of sugar carbon, moistened the mixture slightly with turpentine, and pressed it into the form of a cylinder, which he heated in his electric furnace, using six hundred amperes under fifty volts. A violent reaction took place in accordance with the equation ...

Manganese Carbide, Mn,C solid, d 6.89 at 17q, was first prepd by Troost Hautefeuille. Moissan prepd it by heating in an elec furnace a mixt of Mn304 with sugar-carbon. Other methods of prepn are given in Refs 1 3 Refs l)Beil 1,(8), [111 128 2)H. 

Like phosphate, the nucleotidyl group (UMP or AMP, for example) is an excellent leaving group, facilitating nucleophilic attack by activating the sugar carbon to which it is attached. 

For example, Hoogsteen proposed an alternative A-T pairing using the 6-NH2 and N-7 of adenine.34 Here the distance spanned by the base pair, between the C-T sugar carbons, is 0.88 nm, less than the 1.08 ran of the Watson-Crick pairs. Duplexes of certain substituted poly (A) and poly (U) chains contain only Hoogsteen base pairs35 and numerous X-ray structure determinations have established that Hoogsteen pairs...

The combination of a 5-membered carbohydrate ring and a purine or pyrimidine is called a nucleoside. The rings are numbered as shown in the following figure. The two rings of a nucleoside or nucleotide must be distinguished from each other, so the positions of the sugar carbons are denoted with a (prime) notation. If one or more phosphates exist on the carbohydrate, the combination is called a nucleotide. For example, ATP is a nucleotide.
