The pentose sugar in DNA (2′-deoxyribose) differs from the sugar in RNA (ribose) by the absence of a hydroxyl group (−OH) on the 2′ carbon of the sugar ring.
Glucose moieties with acylations at multiple carbon atoms of the sugar ring are observed (Table 2).
To form their nanonecklaces, scientists threaded sugar ring molecules on a polymer string.
In this way we have prepared analogs of known A3 agonists with the sugar ring restricted in an N-conformation.
The phenylboronic acid can specifically recognize and form a reversible boronate ester with cis-diols moieties, including on a sugar ring (Dowlut and Hall 2006) (Figure S2).
Organic chemistry has systematically probed the chemical determinants of function in nucleic acids by variation to the nucleobase, sugar ring and backbone moieties to build synthetic genetic polymers.
It has also been noted that intercalator molecules produce significant changes in the values of the phase angle P of pseudorotation conformation of the sugar ring.
Unlike with the substrates, the 4-hydroxyl group of the inhibitor's sugar ring seems to be crucial for binding the inhibitor to the active sites of these enzymes.
The term spironucleoside was introduced in 1990 to designate a class of spiranic sugar derivatives in which the anomeric carbon belongs to both the sugar ring and to a heterocyclic base [4 6].
Considering that the structure and size of nucleosides are different and the pentose sugar ring in the nucleosides cannot be accommodated in the electrode gap, we adjust the nucleoside position so that the vast majority of the base body can be included in the scale of electrode surface, and expectantly, the configuration would give the maximal value of electronic transport.
For the simple sugar molecules, such as glucose, which has two cis-diols on the sugar ring, making them easier to bind to the boronic acid moieties, and thus lower the detection limits of the PMNPs method; (ii) The MALDI-TOF MS also an important technique to improve the detection sensitivity.
