Quizplus · Accepted Answer

Keratin is a fibrous protein that forms the structural framework of cells in the outermost layer of the skin, nails, and hair. It provides strength and resilience to these structures, protecting them from damage and decay. Melanin is a pigment that gives color to the skin, eyes, and hair, while carotene is a precursor to vitamin A that is important for vision and skin health. Elastin and collagen are other proteins found in the skin and connective tissue, but they have different functions than keratin.
