The Action of Peroxyl Radicals, Powerful Deleterious Reagents, Explains Why Neither Cholesterol Nor Saturated Fatty Acids Cause Atherogenesis and Age-Related Diseases
Time to rethink: Cells communicate by release of polyunsaturated fatty acids and their peroxidation. In case of severe cell injury, this physiological process switches to generate peroxyl radicals. Radicals randomly attack all biomolecules in proximity to the impact site, forming a plethora of products. In this Review it is demonstrated that peroxyl radicals react differently compared with molecule–molecule reactions involving functional groups and how they influence health and aging. The graphic presentation shows how protonated superoxide radicals are generated and oxidize alcohols. [Review]

Angewandte Chemie 45/2014: Mechanics and Chemistry
In this issue, P. Fratzl et al. review the mechanical role of metal ions in biogenic protein-based materials. How do protein–metal interactions influence properties such as hardness, toughness, adhesion, and self-healing? The Highlights deal with the characterization of nanoporous solids by three complementary techniques (J. M. Thomas and R. K. Leary) and the conversion of CO2 to methane on copper surfaces (M. Behrens).
In the Communications section, M. Sprik et al. describe how to align electronic and protonic energy levels of proton-coupled electron transfer in water oxidation on aqueous titania (see picture). D. P. Fairlie et al. succeeded in making a cyclic heptapeptide orally bioavailable. W.-J. Xiao et al. reveal the photocatalytic generation of N-centered hydrazonyl radicals, and G. R. Newkome et al. report on the fractal design and chemical reality of a self-assembled terpyridine-CdIISierpinski triangle.
The Smallest Marches to a Different Tune
Fundamental change in the nature of chemical bonding upon isotopic substitution
Isotopes are atoms of the same element that have the same number of protons but a different number of neutrons. Because of the resulting differences in mass ratios, isotope effects can significantly influence the formation and breaking of chemical bonds in the course of chemical reactions. In extreme cases, isotopic substitution can even cause a fundamental change in the type of chemical bond, as reported by scientists in the journal Angewandte Chemie.
