Beta Keratin is a type of protein found in the skin, feathers, and scales of various animals, particularly reptiles and birds. It is a fibrous protein that provides structural support and protection, contributing to the strength and durability of these tissues. Unlike Alpha Keratin, which is found in mammals, Beta Keratin has a different molecular structure that allows it to form more rigid and resilient structures. This protein plays a crucial role in the evolutionary adaptations of species, helping them survive in diverse environments. For example, the tough scales of snakes and the strong feathers of birds are largely composed of Beta Keratin, enabling them to thrive in their respective habitats.
