In a nucleotide, to which carbon in the sugar is the base attached? What are sugars such as glucose, fructose, and ribose examples of? What are nucleic acids made of? What component of nucleic acids contains genetic information? What are the macromolecules DNA and RNA referred to as?
A Nucleoside Diphosphate Sugar refers to a type of sugar nucleotide profiled in organisms like the single-celled alga Euglena gracilis to understand their glycosylation capacity. It is a crucial component involved in various biological processes related to cell growth and metabolism. ...
The time-resolved SNA assays described above are superior to any other currently available techniques for the quantitative assessment of the binding and incorporation of different substrates and the effects of active site residues therein. However, these assays have several limitations: the nucleotide inc...
Figure 4.7.8.Left: Singly occupied molecular orbital (SOMO) of the solvated cytosine nucleotide anion represented at the equilibrium RCOdistance (top). Following electron capture, the excess electron is then localized in the π* orbital of cytosine. At a large value RCOdistance (bottom) after th...
What are the simplest units of sugar? They can exist alone or as a monomer of a disaccharide or polysaccharide. ___ is a simple sugar (a monosaccharide). a. Ribose b. Sucrose c. Starch d. All are monosaccharides. Wha...
(e.g., ribose-5-phosphate), while cellular energy and additional metabolites are obtained from an externally supplied organic carbon source (e.g., pyruvate). The successful evolution of a hemiautotrophic strain was the first proof-of-concept demonstration that a non-native carbon fixation pathway...
Leaving aside enantiomorphism, a crescendo stereo-complexity goes from glyceraldehyde, the first chiral sugar, to hexoses. For aldopentoses there are four possible diastereomeric pairs. Why ribose (or 2-deoxyribose) was selected as the structural component of nucleic acids is far from being evident...

Ribosamine is a component of puromycin, desosamine is present in erythromycin, daunosamine occurs in the anticancer anthracycline daunomycin and different amino sugars and its derivatives are found in aminoglycoside antibacterial antibiotics. In each case, the amino sugar moiety is important for ...
The deoxysugar glycosides present on many polyketides are a necessary component for biological activity and, therefore, represent a natural extension of combinatorial biosynthesis (Fig. 5). An epimeric glycoside for the antitumor compound doxorubucin was among the first to be engineered [47]. Several...
