same number of each different
amino acid that form them
necessarily identical proteins?

Even if many have the same
number of each different amino acid
that form them, for example, 50
, 70 and 20 ,
the sequences in which these amino
acids are connected may be very
different. So if two or more proteins are
in such condition of similarity
for each type oftheir constituent amino
acids, they are not necessarily identical.
