Stereospecific recognition of chiral molecules is ubiquitous in chemical and biological systems, thus leading to strong demand for the development of enantiomeric drugs, enantioselective sensors, and asymmetric catalysts. In this study, we demonstrate the ratio of d-Cys and l-Cys playing

Chiral nanostructures from metals and semiconductors attract wide interest as components for polarization-enabled optoelectronic devices. Similarly to other fields of nanotechnology, graphene-based materials can greatly enrich physical and chemical phenomena associated with optical and electronic properties of chiral nanostructures and

In several organisms D-cysteine desulfhydrase (D-CDes) activity (EC 4.1.99.4) was measured; this enzyme decomposes D-cysteine into pyruvate, H2S, and NH3. A gene encoding a putative D-CDes protein was identified in Arabidopsis thaliana (L) Heynh. based on high homology to an

Water-soluble ligand protected optically active silver nanostructures were synthesised in a one-step reduction and capping process mediated by thiol-containing biomolecules. The synthesis was performed successfully with d- and l-cysteine and l-glutathione. The chiroptical properties of the obtained nanostructures were investigated
