difference between them is the mirror-symmetry between their three

dimensional structures, which is similar to that of a person's right and left
hands. Amino acids of either of these two types are found in equal num-
bers in nature and they can bond perfectly well with one another. Yet,
research uncovers an astonishing fact: all proteins present in the structure
of living things are made up of left-handed amino acids. Even a single
right-handed amino acid attached to the structure of a protein renders it
useless.
Let us for an instant suppose that life came into existence by chance as
evolutionists claim. In this case, the right and left-handed amino acids that
were generated by chance should be present in nature in roughly equal
amounts. The question of how proteins can pick out only left-handed
amino acids, and how not even a single right-handed amino acid becomes
involved in the life process is something that still confounds evolutionists.
In the Britannica Science Encyclopaedia, an ardent defender of evolution,
the authors indicate that the amino acids of all living organisms on earth
and the building blocks of complex polymers such as proteins have the
same left-handed asymmetry. They add that this is tantamount to tossing a
coin a million times and always getting heads. In the same encyclopaedia,
they state that it is not possible to understand why molecules become left-
handed or right-handed and that this choice is fascinatingly related to the
source of life on earth. 13

It is not enough for amino acids to be arranged in the correct numbers,
sequences, and in the required three-dimensional structures. The formation
of a protein also requires that amino acid molecules with more than one
arm be linked to each other only through certain arms. Such a bond is
called a "peptide bond". Amino acids can make different bonds with each
other; but proteins comprise those and only those amino acids that join
together by "peptide" bonds.
Research has shown that only 50 % of amino acids, combining at ran-
dom, combine with a peptide bond and that the rest combine with differ-
ent bonds that are not present in proteins. To function properly, each
amino acid making up a protein must join with other amino acids with a
