of the carbon atoms in the sugar are given primes, i.e., 1', 2', etc. The
nucleoside illustrated (LX) is 9-adenyl-/?-D-ribofuranoside. Nucleosides
of both D-ribose and 2-deoxy-D-ribose frequently occur esterified at C-5'
or C-3' by phosphate. Such compounds are termed nucleotides, or more
specifically, ribotides or deoxyribotides.
The nucleic acids are constituted from large numbers of ribo- or
deoxyribonucleotides linked in chains through phosphate (LXI).

It is not intended, in this chapter, to consider these substances to
any great extent, as they are fully dealt with elsewhere. The foregoing
structures have been given in order to offer a comparison between the
"O-glycosides" and their "N" analogs. It may be noted that neither
D-ribose nor 2-deoxy-D-ribose have ever been detected in any form of
