Enzymes are pro-
teins with a tertiary
structure. The amino
acids making up the pro-
tein bend and fold to give
each enzyme its particular
form. Enzymes' tasks are deter-
mined as a result of the bends
and folds in these tertiary structures.

side chains it carries. The characteristic of the amino acids constituting
enzymes is that they interact with one another, as a result of which they
acquire a three-dimensional form that allows the chain to bend and
curve.
How these amino acids are arranged gives the resulting proteins

various properties. Accordingly, proteins assume what are called pri-
mary, secondary, tertiary and quaternary structures. In the primary
structure, a flat polypeptide chain operates. In the secondary structure,
the protein acquires a three-dimensional shape and its functions are de-

termined according to its particular three-dimensional shape. The
polypeptide chains are packed in the same horizontal plane and give
the protein a helix shape. In a tertiary structure, that helix structure in
question assumes a special shape by becoming bent. In a quaternary
structure, all the emerging subunits come together, giving rise to a
