The beta-keratins in feathers, beaks and claws - and the claws, scales and shells of reptiles - are composed of protein strands hydrogen-bonded into beta-pleated sheets, which are then further twisted and crosslinked by disulfide bridges into structures even tougher than the alpha-keratins of mammalian hair, horns and hoof.
