The term "functional potential" was introduced to better approach to the un
derstanding of the relationships between the structure and the functional p
roperties of food proteins. Although in practice the complex of structural
features of a protein contributes to its functionality, it is very useful t
o regard the functional potential of the protein surface on the one side an
d to look on special effects of protein conformation (role of compact or un
folded state) on the functionality on the other side.
