Exempel på hur du använder CHIRAL i en mening

• Tacticity (from , "relating to arrangement or order") is the relative stereochemistry of adjacent chiral centers within a macromolecule.
• Like almost all other amino acids, the α-carbon is chiral and lysine may refer to either enantiomer or a racemic mixture of both.
• Sharpless asymmetric dihydroxylation (also called the Sharpless bishydroxylation) is the chemical reaction of an alkene with osmium tetroxide in the presence of a chiral quinine ligand to form a vicinal diol.
• There are two chiral centres, which in natural compounds like cobalamin have the same stereochemistry.
• There are a total of 20 regular and semiregular polyhedra, aside from the infinite family of semiregular prisms and antiprisms that exists in the third dimension: the 5 Platonic solids, and 15 Archimedean solids (including chiral forms of the snub cube and snub dodecahedron).
• The chiral condensate in quantum chromodynamics, about a factor of a thousand smaller than the above, gives a large effective mass to quarks, and distinguishes between phases of quark matter.
• This model also exhibits a spontaneous symmetry breaking of the U(1) symmetry due to a chiral condensate due to a pool of instantons.
• Many physicists suspect that the fact that the observable universe contains more matter than antimatter is caused by a chiral anomaly.
• Glyceraldehyde has one chiral center and therefore exists as two different enantiomers with opposite optical rotation:.
• Each cavity has chiral tetrahedral symmetry, and the cavities around these two chloride locations are mirror images one of the other (a glide plane or a four-fold improper rotation takes one into the other).
• Prelog was able to separate the chiral enantiomers of Tröger's base in 1944 by chromatography on an optically active substrate.
• The chemical reaction called Sharpless asymmetric dihydroxylation can be used to produce chiral diols from alkenes using an osmate reagent and a chiral catalyst.
• Stereocenters can exist on chiral or achiral molecules; stereocenters can contain single bonds or double bonds.
• Like other pyrethroids, bifenthrin is chiral; it has different enantiomers which can have different effects.
• The aldotetroses have two chiral centers (asymmetric carbon atoms) and so 4 different stereoisomers are possible.
• At low energies, type IIB string theory is described by type IIB supergravity in ten dimensions which is a chiral theory (left–right asymmetric) with (2,0) d=10 supersymmetry; the fact that the anomalies in this theory cancel is therefore nontrivial.
• Like polyominoes, polycubes can be enumerated in two ways, depending on whether chiral pairs of polycubes (those equivalent by mirror reflection, but not by using only translations and rotations) are counted as one polycube or two.
• Isohedral variations with the same chiral octahedral symmetry can be constructed with pentagonal faces having 3 edge lengths.
• Negating all vertices in both groups gives the mirror of the chiral snub dodecahedron, yet results in the same pentagonal hexecontahedron convex hull.
• In May 2023 the same authors published a chiral aperiodic monotile with similar but stronger constraints.
