Fibril and hence the whole muscle. Elastin is a fibrous protein common in various soft tissues, like skin, blood vessels and lung tissue. Each monomer connects with each other, forming a 3D network, with ability to endure over 200% strain before deformation. Keratin is a structural protein mainly found in hair, nails, hooves, horns, quills. Basically keratin is formed by polypeptide chains, which coil into α-helices with sulfur cross-links or bond into β-sheets linked by hydrogen bonding. β-keratin, which is tougher than α-conformation, is more common in birds and reptiles. Resilin is an elastomeric insect protein, consisting of both α-helices and
Hair gel punk subculture in the 1980s. Some hair gels include temporary hair coloring, which includes variants in unnatural colors associated with various subcultures, such as the goths, ravers, and greasers. In films and on television, mobsters and government agents are also well-known for using hair gel in similar ways to each other, goths, and greasers. Cationic polymers are among the main functional components of hair gel. The positive charges in the polymers causes them to stretch, making the gel more viscous. Hair gels resist natural protein conformations and allow hair to be styled and textured, because the stretched-out polymer takes up
