In this chapter, I discuss the main results obtained when calculating the polar
profile of two important groups of proteins: globular and fibrous proteins, by polarity
index method (Sect. 3.3). This classification, unlike other proteins mentioned in
previous chapters of the book, is not a sub-division but a major classification from
which all protein classifications come from.
Keywords: Fibrous proteins, Globular proteins, Polar profile, Polarity index
method.
