Antifreeze proteins (AFP) are responsible for the survival of several species, ranging from bacteria to fish, that encounter subzero temperatures in their living environment. AFPs have been divided into two main families, moderately and hyperactive, depending...
A natural bond orbital analysis of the distonic bicyclo[2.2.1]hepta-2-ene-5-yl-7-ylium radical cation interprets its structure and radical character by a three-center two-electron bond between C2, C3, and C7 (a bishomoaromatic stabilization) and a singly...

Diamonds may be forever, but are some other forms of carbon merely passing fads? Stuart Cantrill considers why carbon often seems to be a chemist's best friend.
Smart phones and tablets have revolutionized how we communicate, access and use information, work, travel, play and learn. Chemistry education and the field of chemistry have not surprisingly been positively impacted by this technologyâ¦
Long-range communication of stereochemical information is common in biological systems, particularly in enzyme-catalysed reactions. Here, we report the remote control of the dynamic chirality of metal centres, coordinated by 2,2â²-bipyridine ligands bearing...
It is recognized widely that enzymes promote reactions by providing a pathway that proceeds through a transition state of lower energy. In principle, further rate enhancements could be achieved if intermediates are prevented from relaxing to their lowest...
Developing cleaner chemical processes often involves sophisticated flow-chemistry equipment that is not available in many economically developing countries. For reactions where it is the data that are important rather than the physical product, the networking...
Terpenes comprise a class of natural products that includes molecules with thousands of distinct structurally and stereochemically complex molecular architectures. The core hydrocarbon frameworks of these molecules are constructed via carbocation...
A classic calcium aluminate has been modified to create an inorganic electride that can be used as a promoter of the catalytic synthesis of ammonia.
Ironâsulfur clusters are common cofactors in biological systems and are involved in a range of functions, including electron transfer, substrate binding and activation. These clusters are usually ligated by the cysteine residues of a protein, but there are...
There has been only one example reported so far of a terminal phosphorus monoxide complex. The chemistry of this functional group, therefore, is unexplored compared with others containing main-group elements.
With the intention of improving synthetic efficiency, organic chemists have turned to bioinspired organocascade or domino processes that generate multiple bonds and stereocentres in a single operation. However, despite the great importance of substituted...
The tunicamycins are archetypal nucleoside antibiotics targeting bacterial peptidoglycan biosynthesis and eukaryotic protein N-glycosylation. Understanding the biosynthesis of their unusual carbon framework may lead to variants with improved selectivity....
With energy swiftly rising to the top of the world's agenda, Harry B. Gray at the California Institute of Technology looks at how chemistry can help to harness the power of the Sun to meet the world's energy needs.
Halogens are commonly used to initiate changes on platinum surfaces for the preparation of catalysts. They are also involved in electrode etching, a selective corrosion process used to prepare devices such as semiconductors â but the halogenâplatinum...
