Web1 day ago · For molecules, this property is called chirality, and the left and right forms are two enantiomers. At some point in the evolution of life, nature evidently chose to favor one hand in some of its chemistry. For example, l-amino acids are used predominantly rather than d-amino acids. The reason for this symmetry breaking, this biohomochirality ... WebThe enantiomers of twelve unusual β2- and β3-homoamino acids containing the same side-chains were separated on chiral stationary phases containing a quinine- or quinidine …
