Quizplus · Accepted Answer

A-keratin is a protein found in hard structures like hair, nails, claws, and horns, and is composed of 4 helical strands arranged as twisted pairs of 2-stranded coiled coils with associated hydrophobic strips. It is not, however, the principal constituent of connective tissues in animals. That role is played by collagen.
