                                Beta keratin, a protein with a rigid beta-pleated sheet structure, is found exclusively in reptiles and birds among vertebrates, setting it apart from the more common alpha-keratin found in mammals. This durable protein plays a crucial role in forming protective epidermal appendages in these animal groups. Its unique composition and structure make it less extensible and more resistant than alpha-keratin.
