What is the difference between the protein in the hair of an animal s horn and the protein in the sk

Students who are good at observing life will find that when their hair or nails accidentally touch a fire source, it will emit a smell similar to burning chicken feathers, and curious students may find out that this smell is caused by protein burning.

Nails, hair, chicken feathers, and animal hoofs and claws are all proteins, which are derived from ectodermal cells and are called keratin. It is a kind of water-insoluble fibrous protein, there are two types of keratin and keratin, these two types of proteins are only conformationally different, they can be converted into each other, under humid and hot conditions, keratin turns into keratin, when it is cooled and dried, the spiral is stretched open, the hydrogen bonds between the circles are broken, and it is denatured into a conformation. This is also the theoretical basis of the current curly hair industry, barbers use reducing agent oxidants to break the hydrogen bonds between protein polypeptide bonds, which can straighten curls and straighten hair into curls.

According to the sulfur content, keratin can be divided into two categories: hard keratin and soft keratin. The keratin in the claws, horns, nails, and nails is high-sulfur keratin, which is hard in texture and cannot be stretched; **The keratin of the hair is low-sulfur soft keratin, which is more elastic than hard keratin.

Hair is rich in a variety of proteins, it makes hair black, shiny, elastic, at present, there are businesses from black rice to extract a kind of black rice protein, but hair can effectively absorb this protein is still unknown, so we can extract this kind of nutrients from our own hair that can promote hair growth, make it into an oral liquid, for people to take, more conducive to human absorption.

Second, the implementation process and methods.

Step 1 Dissolve.

Because the main component that makes up hair keratin is insoluble in water, but it dissolves in acids, after which it is neutralized with alkali;

Step 2 Coarse fractionation.

Separate the desired protein from other miscellaneous proteins (salting-out, isoelectric precipitation can be used);

Step 3: Segment-level separation.

It was further purified by chromatography gel filtration, adsorption chromatography and affinity chromatography.

Step 4 Crystallization.

The purified protein is crystallized and then recrystallized;

Step 5 Post-processing.

The crystallized protein is dissolved in a solute so that the protein is dissolved and easily absorbed.

3. Summary and harvest.

In daily life, we often get haircuts, and the cut hair is a very valuable resource, and even it contains some proteins in the natural animals and plants in very small amounts, if it is rationally used and developed, it can produce low-cost but great health value of nutrients.

Hormones are divided into protein hormones, steroid hormones, amino acid derivatives hormones and so on according to their chemical nature.

Neurotransmitters are acetylcholine, adrenaline, derivatives of some amino acids, etc.

The horns of the hooves should contain keratin, and the skin and bones contain collagen.

The supplementary question is not very clear ...

The skin of the animal's flesh is collagen.

Collagen is a biological polymer, the connective tissue of animals.

The main ingredient in mammals, too.

The most abundant and widely distributed functional protein in the body, accounting for 25% to 30% of the total protein, and even as high as 80% in some organisms.

Classify. Collagen is a family of proteins, at least more than 30 kinds of collagen chain coding genes have been discovered, can form more than 16 kinds of collagen molecules, according to its structure, can be divided into fiber collagen, basal membrane collagen, microfiber collagen, anchor collagen, hexagonal reticular collagen, non-fiber collagen, transmembrane collagen, etc.

According to their distribution and functional characteristics in the body, collagen can be divided into interstitial collagen and basement membrane.

Collagen and cellular peripheral collagen. Interstitial collagen molecules account for the vast majority of the collagen disturbance in the whole body, including Paitong collagen.

Molecule. According to function, collagen can be divided into two groups, the first group is fibroblast collagen, including type, type collagen; The rest is the second group, non-fibroblast collagen.
