- Are proteins with the
same number of each different
amino acid that form them
necessarily identical proteins?
Even if many proteins havnumber of each different amino acide the same

- What is the essential
condition for a protein to be
identical to another protein?
For a protein to protein it is necessary for the sequencebe identical to another (^)
of amino acids that form them to be
identical.
- What is the primary
structure of a protein? What is
the importance of the primary
structure?
The primary protein structure is the
linear sequence of amino acids thatform the molecule.

- What is the secondary
structure of a protein?
The secondary protein structure is
generated by the manner its aminoacids interact through the
intermolecular bond. These interactions
