The separation of nucleotides by isotachophoresis

Journal of Chromatography A, 1972
The mono-, di-, and triphosphates of adenosine, cytidine, guanosine, and uridine were sepd. by isotachophoresis in several different electrolyte systems. At lower pH, the differences in step-height were greater, and complete sepn. of a mixt.

Fluorescent and colorimetric chemosensors for detection of nucleotides, FAD and NADH: highlighted research during 2004-2010.

Chemical Society Reviews, 2011
Due to the biological importance of nucleotides and related species, such as XNP (where X = adenosine (A), uridine (U), cytidine (C), guanosine (G), and N = mono, di, tri), FAD and NADH, the development of optical probes for these molecules has recently ...

tRNA stabilization by modified nucleotides.

Biochemistry, 2010
Post-transcriptional ribonucleotide modification is a phenomenon best studied in tRNA, where it occurs most frequently and in great chemical diversity.

Mechanisms of release of nucleotides and integration of their action as P2X- and P2Y-receptor activating molecules.

Molecular Pharmacology, 2003
The concept that adenine and uridine nucleotides function as extracellular signaling molecules has been markedly expanded in the last decade. At least 15 nucleotide-activated cell surface receptors exist, and remarkably broad and varied physiological ...

The role of nucleotides in the immune and gastrointestinal systems: potential clinical applications.

Nutrition in clinical practice, 2012
Nucleotides are low molecular weight biological molecules key to biochemical processes. Sources include de novo synthesis, recovery via salvage mechanisms, and dietary intakes. Although endogenous production serves as the main nucleotide source, evidence

Reduction of cytidine nucleotides to deoxycytidine nucleotides by mammalian enzymes

Biochimica et Biophysica Acta, 1962
Abstract 1. 1. Conditions for the reduction in vitro of cytidine nucleotides to deoxycytidine nucleotides by an extract of the Novikoff ascites rat tumor are described. ATP was required; TPN, Mg 2+ and Fe 3+ stimulated the reaction. The effects of other metal ions and of a number of organic compounds on the reaction are described. 2.

Nanoparticles of adaptive supramolecular networks self-assembled from nucleotides and lanthanide ions.

Journal of the American Chemical Society, 2009
Amorphous nanoparticles of supramolecular coordination polymer networks are spontaneously self-assembled from nucleotides and lanthanide ions in water. They show intrinsic functions such as energy transfer from nucleobase to lanthanide ions and excellent

Nucleotide und Nucleinsäuren

2002
Nucleotide wurden erstmals als Bausteine der Nucleinsauren gefunden. Sie sind in charakteristischer Weise aufgebaut und haben inzwischen einer ganzen Substanzklasse gleichermasen aufgebauter Verbindungen ihren Namen gegeben.
