THE non-enzymatic asymmetric synthesis of α-amino-acids has long been of considerable stereochemical interest. However, the method of catalytic hydrogenation is the only one appearing in the ...
All DNA and RNA found in all Earth life forms are made from "right-handed" molecules, while proteins are made from nearly entirely "left-handed" amino acids. The chirality of a molecule can ...
They have what is called structural asymmetry, or chirality, which means that they can have alternative, mirror-image versions similar to left and right versions of a human hand. DNA and RNA are made ...
