RACEMASE ENZYMES change chirality of their substrates. Alanine racemase converts the amino acid L-alanine into its mirror opposite for construction of bacterial cell walls. https://lnkd.in/eMZemZs View in LinkedIn

PSEUDOSYMMETRY. "The racemase enzyme family catalyze the interconversion of both substrate enantiomers. Although most enzymes are exquisitely asymmetric, by definition racemases process both enantiomers...how can they do this? Racemases have evolved a functional and structural pseudosymmetry in their active sites." https://lnkd.in/e47-EFF View in LinkedIn

PROCHIRAL MOLECULES. "Molecular surface structures often show important stereochemical effects as, aside from truly chiral molecules, a large class of so-called prochiral molecules become chiral once confined on a surface with an associated loss of symmetry." https://lnkd.in/e6_s2ru View in LinkedIn

CHIRAL SWITCHING. "Appropriate prochiral molecules may be induced (for example, by seeding) to assume only one enantiomer form." https://lnkd.in/e6_s2ru View in LinkedIn

INDUCED SWITCHING. "In a model system, prochiral molecules can be induced to switch between enantiomers." https://lnkd.in/eH6ANmH View in LinkedIn

OPTICAL CHIRAL SWITCHES are an advance on older photoelectric switches, making optically switchable chiral molecules which break mirror symmetry to induce chirality. https://lnkd.in/eMDnvbY View in LinkedIn

INVERSION OF CHIRALITY just by changing the metal in an organic chemical system. Elegant. https://lnkd.in/eMTagVz View in LinkedIn

"CHIRALITY is a very important parameter to consider in liquid crystals. The liquid crystalline state is a state of matter which is characterized by the alignment of molecules or molecular aggregates." https://lnkd.in/eD3BZKr View in LinkedIn

CHIRALITY AND LIQUID CRYSTALS. "The unique combination of high birefringence with the possibility to modulate either the direction of the optical axis or the optical retardation by an external electric field is the basis for electro-optic applications of liquid crystals." https://lnkd.in/eD3BZKr View in LinkedIn

DROPLETS. "The director configurations of confined liquid crystals exhibit a rich phenomenology, the physics of which is determined by a delicate interplay of topology, elastic free energy, and anchoring conditions at the boundaries." https://lnkd.in/ejxwdgM View in LinkedIn
