The Alkali Metal Ions: Their Role for Life by Astrid Sigel, Helmut Sigel, Roland K. O. Sigel

By Astrid Sigel, Helmut Sigel, Roland K. O. Sigel

MILS-16 offers an updated assessment of the impression of alkali steel ions on lifestyles. Their bioinorganic chemistry and analytical decision, the forged country constructions of bio-ligand complexes and the homes of alkali steel ions in resolution within the context of all types of biologically correct ligands are lined, this contains proteins (enzymes) and nucleic acids (G-quadruplexes). Minerals containing sodium (Na+) and potassium (K+) are plentiful within the Earth's crust, making Na+ and K+ simply to be had. against this, the alkali parts lithium (Li+), rubidium, and cesium are infrequent and the radioactive francium happens in simple terms in lines. because the intra- and extracellular, in addition to the compartmental concentrations of Na+ and K+ range considerably, homeostasis and energetic shipping of those ions are vital; this consists of transporters/carriers and pore-forming ion channel proteins. platforms like Na+/K+-ATPases, H+/K+-ATPases or Na+/H+ antiporters are completely mentioned. The function of K+ in photosynthesis and the function of Na+ in charging the "battery of existence" are mentioned. additionally, the relationships among alkali steel ions and illnesses (e.g., Parkinson or demanding mind harm) are lined and the relevance of Li+ salts in medication (pharmacology and mechanism) is reviewed. This and extra is handled in an authoritative and well timed demeanour within the sixteen stimulating chapters of quantity sixteen, The Alkali steel Ions: Their position for Life, that are written by way of forty four the world over well-known specialists from 12 countries. The influence of this bright learn quarter is manifested in approximately 3000 references, over 30 tables and greater than one hundred fifty illustrations (two thirds in color). MILS-16 additionally presents first-class info for teaching.

Astrid Sigel, Helmut Sigel, and Roland ok. O. Sigel have long-standing pursuits in Biological Inorganic Chemistry. Their study specializes in steel ion interactions with nucleotides and nucleic acids and on comparable issues. They edited formerly forty four volumes within the sequence Metal Ions in organic Systems.

Säure-Base-Diagramme: Ein Leitfaden für die Praxis und für Studierende

​Das Buch gibt eine Anleitung zur Beschreibung von Säure-Base-Gleichgewichten mithilfe von einfach zu konstruierenden Diagrammen, die es erlauben,- pH-Werte von Lösungen grafisch zu ermitteln,- Gleichungen für die Berechnung von pH-Werten abzuleiten (die möglichen Näherungen zu erkennen),- den Verlauf von Titrationskurven einfach auf grafischem Weg zu ermitteln,- die in Säure-Base-Systemen bei bestimmten pH-Werten dominierenden Spezies zu erkennen, usw.

Crown-ethers may be employed as artificial ionophores for these ions, but higher selectivities are often obtained with other compounds, which notably may not be macrocyclic. Some structures and selectivity coefficients are also given in Figure 3 and Table 2 [8–10], respectively. Limits of detection of about 1 μM can be obtained with these ion-selective electrodes in the absence of significant interferences. Based on these ionophores optical chemical sensors have also been developed. These generally employ plastiziced PVC membranes, which besides the ionophore contain a lipophilic pH-indicator.
