>All life on Earth is made of molecules that twist in the same direction
That is...not true, or at least a little misleading. Each class of molecule in earth life twists the same way as other members of that class but not all classes twist the same. For example, nucleotides twist right/D, while amino acids twist left/L.
- mekoka 7y agoFrom the article: Scientists later discovered that this bias encompasses the entire living world. Synthetic chemical processes will generate both left- and right-handed molecules. But when nature makes a molecule, the product is either left- or right-handed. For example, all amino acids that are used to make proteins twist light to the left.
