A statistical survey of the torsion angles, bond angles, and bond lengths in the sugar and phosphate groups of well-refined mononucleoside, mononucleotide, dinucleoside monophosphate, and trinucleoside diphosphate crystal structures contained in the Cambridge Structural Database and the Nucleic Acid Data...
After treatment with carboxypeptidase, chymotrypsin, or subtilisin, aldolase cleaves all of these substrates at the same (deceased) rate; the modified aldolase preparations are also equally impaired in their ability to catalyze the detritiation of specifically labeled dihydroxyacetone phosphate. These ...
Guided by gut sensory cues, humans and animals prefer nutritive sugars over non-caloric sweeteners, but how the gut steers such preferences remains unknown. In the intestine, neuropod cells synapse with vagal neurons to convey sugar stimuli to the brain within seconds. Here, we found that cholecy...
The most generally used synthetic method consists of the formation of the pyrophosphate bond in the coenzyme III through the reaction of various readily prepared and stable nucleoside 5′-phosphoramidates (I) with the appropriate sugar phosphate (II) in an anhydrous organic solvent. The methods ...
whereas nucleoside plus phosphate makes a nucleotide. Hence, nucleoside=sugar+base, whereas nucleotide=sugar+base+phosphate.Table 1.1shows the naming of nucleosides and nucleotides.Each nucleotide in DNA (as well as in RNA) has one replaceable hydrogen, which is what makes the DNA (and RNA) acid...

(Fig.7). Likewise, glyceraldehyde can undergo dehydration to pyruvaldehyde, along with formation of phosphoanhydrides or phosphate esters, so long as phosphate sources are available. Thermodynamic data suggest that most transformations would be viable exergonic processes, albeit no energy barriers were...
C. The cells were collected about 48 h later by centrifugation and washed once in phosphate-buffered saline (pH 7.5; Gibco). Cell pellets were frozen in liquid nitrogen and stored at –80 °C until needed. Cell pellets were thawed on ice and resuspended in 20 ml of lysis buffer ...
To aid the free flow character of icing sugar it is common to add a little tricalcium phosphate. If present, this should be declared, and the quantity is usually up to 1.5%. 11.2.1.1 Calculation of mean aperture and standard deviation of a sample of crystalline sugar A sample of the ...
c. phosphate d. nitrogenous base DNA: DNA (deoxyribonucleic acid) can be defined as the polymer of nucleotides. The nucleotides in the one strand of DNA bind together by a covalent bond. This bond is referred to as the phosphodiester bond. ...
