Alternative structures for Deoxyribose
Note that numbering in the
Haworth structure of Deoxyribose sugar proceeds
clock-wise, with the 5'-C projecting.
This is the numbering system used in molecular biology. The
Fischer structure numbering runs top to bottom, and
is often used in organic chemistry.
HOMEWORK: Briefly
describe the importance of each of the Carbon atoms
in the Haworth structure for the biochemistry of nucleic
acid.
