Proteins in Living Structures Are Formed
from Left-Handed Amino Acids Only

As research has shown, it is not enough for the selected 20
amino acids out of over 200, to combine in different numbers
and sequences to form proteins. All these amino acids must also
be left-handed.
Of every amino acid found in nature, there are two differ-
ent types: right-handed and left-handed. Each type is an oppo-
site mirror image of the other, though all their atoms are the
same, just like right- and left-hand gloves.
The reason for this is that in one of the twin amino acids,

a carbon atom binds to the amino group from the left and in the
other one, from the right, which explains why the twin amino
acids are called right-handed and left-handed. Both types of
amino acid can just as easily form various compounds by enter-
ing into chemical reactions. In short, the only difference be-
tween the two lies in their different symmetry.
However, scientists discovered that the proteins in living

things consisted only of left-handed amino acids. Not a single
right-handed amino acid was used in any living structure.
