Alpha-keratin, or α-keratin, is a type of keratin found in mammalian vertebrates.This protein is the primary component in hairs, horns, claws, nails and the epidermis layer of the skin. α-keratin is a fibrous structural protein, meaning it is made up of amino acids that form a repeating secondary structure.
It originates from the actively growing tissue below, the matrix. [citation needed] The nail plate (corpus unguis) [3] sometimes referred to as the nail body, is the visible hard nail area from the nail root to the free edge, made of translucent keratin protein. Several layers of dead, compacted cells cause the nail to be strong but flexible.
Keratin (/ ˈ k ɛr ə t ɪ n / [1] [2]) is one of a family of structural fibrous proteins also known as scleroproteins. It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin in vertebrates. Keratin also protects epithelial cells from damage or stress. Keratin is extremely ...
The integumentary system includes skin, hair, scales, feathers, hooves, claws, and nails. It has a variety of additional functions: it may serve to maintain water balance, protect the deeper tissues, excrete wastes, and regulate body temperature, and is the attachment site for sensory receptors which detect pain, sensation, pressure, and ...
A nail is homologous to a claw but is flatter and has a curved edge instead of a point. A nail that is big enough to bear weight is called a "hoof". (Nevertheless, one side of the cloven-hoof of artiodactyl ungulates may also be called a claw). Every so often, the growth of claws stops and restarts, as does hair. In a hair, this results in the ...
