Did life’s predilection for so-called “left-handed” amino acids evolve as a quirk of prebiotic chemistry here on Earth? Or did biomolecules’ reliance on single “chirality” or handedness actually have ...

All biological amino acids on Earth appear exclusively in their left-handed form, but the reason underlying this observation is elusive. Recently, scientists uncovered new clues about the cosmic ...

Scientists have created a synthesis method to make optically active and chiral gold nanoparticles using amino acids and peptides for the first time. Many chemicals significant to life have ...

Chiral analysis of amino acids has gained considerable prominence as researchers strive to understand the subtle roles that enantiomers play in biological systems. The ability to distinguish between ...

In this paper, we report on discriminations and factors associated with amino acids that can affect the chiroptical properties of PANI(+)-HCSA emeraldine salt products prepared by doping of PANI with ...

A new paper from noted American chemist Ronald Breslow was recently accepted by the Journal of the American Chemical Society. It's titled, "Evidence for the Likely Origin of Homochirality in Amino ...

Doubly stapled α-helix consisting only of achiral amino acids. Its one-handed form can be isolated because the interconversion between the right- and left-handed forms is almost completely suppressed.

Proceedings of the National Academy of Sciences of the United States of America, Vol. 99, No. 8 (Apr. 16, 2002), pp. 5115-5120 (6 pages) In a systematic study of molecular recognition of amino acid ...

Activating the relatively inert C–H bond enantioselectively and catalytically can already be achieved through several approaches, but none of these techniques involve formation of a chiral ...

For medicinal chemists, making tweaks to peptide structures is key to developing new drug candidates. Now, researchers have demonstrated that two iron-containing small-molecule catalysts can help turn ...

In this episode of Tiny Show and Tell Us, we cover why your body feels so ‘off’ at high altitudes and how we’ve evolved not to detect low oxygen levels but high amounts of carbon dioxide. Then we ...
