Keratin is a component 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 is perfectly soluble not only in alkalis, but also in sodium and potassium solutions. In the process of decomposition, like other proteins, it breaks down into ammonia, fatty acids, tyrosines, hydrogen sulfide and leucines.
What is keratin
This is a fairly strong protein and a very important component in human skin. It plays an important role in the hair, nails, teeth (as well as the hooves and horns of animals). Its structure contains amino acids, which have very useful properties. In a wide variety of compounds, such a substance can be either very soft (for example, skin) or very hard (animal hooves). Keratin for hair is extremely important. It contains dead cells. They perfectly protect that delicate layer that is just beginning to form.
Production of keratin
This substance contains cysteine disulfide, which allows you to create two-sulfidebridges. Such chains look like a spiral structure, 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 pretty important. It contains a lot of sulfur, which, during 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 tend to rise all the time, and after they die, they begin to form a kind of protection. Keratin can be damaged during psoriasis. At this time, the peeling process appears.
What does keratin mean for hair and nails?
Over time, nails and hair begin to become dry and brittle. When keratin cells die, this process is greatly accelerated. A similar phenomenon can be stopped if you eat gelatin and regularly moisturize your hair. For these purposes, liquid keratin for hair is perfect. With it, the curls will acquire shine and will look well-groomed and neat. The larger the layer of such a substance, the he althier the hair and nails will be. Extra hydration will help keep them he althy and protect them from damage.
