Are Alpha Helices Amphipathic?

As the name implies, an amphipathic (or amphiphilic) helix is an α-helix with both hydrophobic and hydrophilic amino acid residues arranged in such a way as to create two faces on opposite sides of the helix, one face being hydrophobic. ... Note that all three α-helices are at the surface.

When α helices are described as being amphipathic It means that?

When an alpha helix is amphipathic, it means that one side of the helices is mainly hydrophobic and the other side is mainly hydrophilic.

Are alpha helices hydrophobic?

Some α-helices have mainly hydrophobic residues, which are found buried in the hydrophobic core of a globular protein, or are transmembrane proteins.
