ALL PROTEINS IN LIVING BEINGS ARE LEFT-HANDED;
A FACT THAT CANNOT BE EXPLAINED BY CHANCE
For amino acids to form a functional protein, combining in
the right number, in the right sequence and in their right three
dimensional design is not enough. All the amino acids, without
exceptions, must also combine to form a protein that is “left-
handed.”
Chemically, all amino acids exist in either right-handed or
left-handed form, their three-dimensional structures being sym-
metrical opposites, like human hands.
Amino acids from both camps can easily form bonds be-
tween them. But research has revealed one surprising fact: All
proteins in all life forms, from the most primitive organisms to
the most complex, are formed by left-handed amino acids. Even
one right-handed amino acid within the structure renders it dys-
functional. Some experimenters introduced, right-handed amino
acids into bacteria, and the bacteria immediately destroyed
them. In some cases, the bacteria reconstructed left-handed
amino acids from parts of the original right-handed ones.
For one moment, let’s assume that, as evolutionists claim,
amino acids formed themselves according to the laws of chance.
There should be equal numbers of left and right-handed amino
acids in nature and, consequently, in all living beings as well.
This should be quite possible: Chemically, amino acids from
both groups can easily bond with one another. In reality, though,
all proteins in living beings are exclusively left-handed.
