Keratin for hair. What it is?

Keratin is a constituent of protein, but differs from it in that it contains a large amount of sulfur. It swells well in water, has a rather low specific gravity and dissolves perfectly not only in alkalis, but also in solutions of sodium and potassium. In the process of decomposition, like other proteins, it decomposes into ammonia, fatty acids, tyrosines, hydrogen sulphide and leucines.

What is keratin

It is a strong enough protein and a very important component in human skin. It plays an important role for the hair, the nails of the teeth (and also for hooves and animal horns). Its structure contains amino acids that have very useful properties. In a variety of compounds such a substance can be very soft (for example, skin), and very hard (hooves of animals). Keratin for hair is extremely important. It is based on dead cells. They perfectly protect that gentle layer that is just beginning to form.

Production of keratin

In this substance there is disulfide cysteine, which allows you to create bisulfide bridges. Such chains look like a spiral design, which is very stable, because The sulfur atoms in the helix are very close to each other. Thus, a fibrous matrix is obtained in which the degree of solubility is very high. Such a connection is quite strong and flexible. That's why keratin for hair is quite important. It contains a lot of sulfur, which in the process of combustion forms a persistent unpleasant odor. A similar substance is formed by certain living cells (keratinocytes), which synthesize it. They serve as the basis for hair, nails and skin. These cells all the time tend up, and after they die, they begin to form a kind of protection. Keratin can be damaged during psoriasis. At this time there is a process of peeling.

What does keratin mean for hair and nails?
