What are the types of collagen? What are the collagen proteins

Collagen is a family of proteins, and at least 30 genes encoding collagen chains have been discovered, which can form more than 16 kinds of collagen molecules.

According to its structure, it can be divided into fibrous collagen, basement membrane collagen, microfiber collagen, anchored collagen, hexagonal reticular collagen, non-fibrous collagen, transmembrane collagen, etc.

According to the distribution and function of collagen in the body, collagen can be divided into interstitial collagen, basement membrane collagen, and pericellular collagen.

Types of interstitial collagen molecules that make up most of the body's collagen, including collagen.

Molecular, type collagen is mainly distributed in **, tendons.

and aquatic product processing waste (**, bone and size), one of the richest proteins accounts for 80-90% of the total collagen content, the most widely used drugs.

One of the most striking features of collagen in fish is its low thermal stability and species specificity. collagen is produced by chondrocytes; The basement membrane collagen type, commonly known as collagen, is mainly distributed in the basement membrane; Pericellular extracellular collagen is usually the middle finger type collagen, in connective tissue.

Ubiquitous. According to the function of collagen, it can be divided into two groups, the first group of collagen fibers, including the first, collagen type; The rest is the second group, non-fibrous collagen. The -chain of non-fibroblastic collagen contains three helix domains (COL) and non-triple helix domains (NC), of which fibroblast collagen accounts for about 90% of the total collagen.

1) Oral collagen-containing foods: such as drinking more collagen-rich bone broth, oral collagen supplements, etc. However, due to the fact that a large part of it is filtered out by the human digestive system, and the amount that can really reach the skin and work is very limited, the process is relatively lengthy and inefficient.

And it is not ideal for female friends who want to stay slim.

2) Use skincare products that are rich in collagen and can promote collagen: This is the most effective collagen supplement method at present, but it should be noted that skincare products that contain active collagen ingredients can really enter the dermis to help repair the skin and rebuild the collagen layer.

3) Direct subcutaneous injection: mainly used to fill deep wrinkles, defects caused by damage and repair defects in the face shape. The effect is immediate, but the collagen injected into ** will be gradually absorbed by the human body, so its effect can only last for half a year to a year, and a small number of people may have allergies, infections, etc.

Collagen is a family of proteins, and at least 30 genes encoding collagen chains have been discovered, which can form more than 16 kinds of collagen molecules. According to their distribution and functional characteristics in the body, collagen is currently divided into interstitial collagen, basement membrane collagen, and peripheral cell collagen [2]. Interstitial collagen molecules account for the vast majority of collagen in the whole body, including collagen molecules, which are mainly distributed in tissues, tendons, and other tissues, among which collagen is produced by chondrocytes; Basement membrane collagen usually refers to type collagen, which is mainly distributed in the basement membrane; Pericellular collagen is usually the middle finger type collagen, which is abundant in connective tissue.

Collagen can be divided into food grade, general grade, and pharmaceutical grade according to its application.

There are two types of collagen.

One is hydrolyzed collagen, which has the effect of health care, preventing osteoporosis and improving joint health, and the other is fish scale collagen, which is extracted from fish scales, and fish scale collagen can play a role in whitening. It is very low in calories and can help**.

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, basement membrane collagen, and peripheral cell collagen. Interstitial collagen molecules account for the vast majority of collagen in the whole body, including collagen molecules, collagen is mainly distributed in tissues such as tendons, tendons, etc., and is also the protein with the largest content of aquatic product processing waste (skin, bone and scale), accounting for about 80% and 90% of all collagen content, and is the most widely used in medicine.

One of the most significant characteristics of collagen in fish collagen is its low thermal stability and the specificity of fish species. collagen is produced by chondrocytes; Basement membrane collagen usually refers to the old collagen code, which is mainly distributed in the basement membrane; Cellular peripheral collagen is usually a middle-finger type collagen and is found in large amounts in connective tissue.

Collagen-related

The collagen content in aquatic animals is higher than that in terrestrial animals, such as silver carp, bighead carp and grass carp, respectively6% and , all of which were higher than the protein content of their respective fish3% and, and the collagen content in the skin of the fish can exceed 80% of its total protein, which is much higher than the rest of the fish body.

Collagen is generally a white, transparent powder with elongated rod-like molecules ranging from about 2 kd to 300 kd in relative molecular weight. Collagen has strong elongation, is insoluble in cold water, dilute acid, dilute alkali solution, and has good water retention and emulsification. Collagen is not easily hydrolyzed by general proteases, but it can be broken by animal collagenase, and the broken fragments are automatically denatured, and they can be hydrolyzed by ordinary proteases.

When the environmental pH is acidic, the denaturation temperature of collagen is 38 39.

The above content is from the reference: collagen

Pro, collagen is a structural component of the human body, and there are many types. From a molecular biological point of view, collagen is a class of protein components with molecular weights, ranging from 2kd to 300kd. Collagen is a component of organs and tissues, which can maintain the structure and function of organs and tissues, mainly including the following:

1. Collagen: It is the most abundant in the human body, distributed in the dermis, bones, teeth, tendons and other parts, and is a relatively complex structure, which can also be seen in inflammatory tissues and tumor tissues; 2. Collagen egg hidden vertical chain white: mainly distributed in cartilage, as well as the vitreous, cornea, neuroretina and other parts of the eye, the main function is to maintain the normal function of the above organs and tissues; 3. Type collagen:

Mainly distributed in dermal fiber, cardiovascular, gastrointestinal tract and other parts, the function of collagen is mainly to maintain tissue elasticity and basic structure; 4. Collagen: distributed in the basement membrane and other parts, commonly found in the basement membrane of the kidney and kidney, with high sugar content. The type of gelatinous progenin can be divided into several subclasses; 5. Type collagen:

It is mainly distributed in amniotic membranes and some tissues of the embryo, and when the pregnant woman gives birth, the distribution of collagen in the body will be reduced accordingly. After trauma or burns, some types of collagen are also formed, which are used to promote tissue repair; 6. Collagen: mainly found in embryonic tissue; 7. Type collagen:

It is mainly distributed in tissues such as embryonic chorion and amniotic membrane, and its distribution in the human body is relatively reduced after birth. Different collagen has different functions, and the above are the more common collagen and the collagen that plays a large role. In addition, there are some collagen distributed in the human body in relatively small amounts and the mechanism of action is not particularly clear.

Summary. Hello dear, collagen belongs to one of the proteins. Protein itself is an important component of human cells and tissues, while collagen is a biological polymer substance.

Protein intake alone can accelerate fat decomposition and inhibit fat synthesis; The intake of collagen can increase the elasticity of the skin, eliminate the fine wrinkles, and play an anti-aging role. The protein content in eggs and milk is relatively high, while the collagen content in pig skin, pig trotters and chicken skin is relatively rich. According to the different physiques of each person, different foods can be selected for targeted supplementation.

The content of white matter in eggs and milk is relatively high, while the content of collagen in pig skin, pig trotters and chicken skin is relatively rich. According to the different physiques of each person, different foods can be selected for targeted supplementation.

Ordinary foods or products will be labeled with nutrients, so it is easy to distinguish.

Collagen is a biological polymer, the main component of animal connective tissue, and also the most abundant and widely distributed functional protein in mammals, accounting for 25% to 30% of the total protein, and even up to 80% in some organisms.
