Web11 jul. 2024 · Dextrorotatory amino acids, on the other hand, always give the right to left-handed proteins. A mixture of both forms cannot form helices at all. Similarly, the genetic material deoxyribonucleic acid is always coiled as a right-handed helix. Functional consequences of chirality in biomolecules. WebAn asymmetric autocatalytic reaction has been catalyzed by a mixture of chiral and achiral β-amino alcohols. The absolute configuration of the highly enantioenriched obtained product (>98% ee) was shown to depend not only on the absolute configuration of the chiral catalyst but also on the structure and the amount of achiral catalyst.
