What are the functions of collagen?

Collagen. is a bioactive polymer substance, in.

Human cells. plays the role of a binding organization.

Body composition. About 16% of it is protein, and 30%-40% of protein is collagen, and there are about 3 kilograms of collagen in the adult body, which mainly exists in the human body: **, muscles, bones, teeth, internal organs (intestines, stomach, heart, lungs, blood vessels, esophagus) eyes and other parts.

Collagen plays a role in binding tissues in cells and is abundant.

Glycine. Proline.

And. Hydroxyproline.

**70% of the ingredients are made up of collagen. Hydroxyproline in collagen is:

Human body**. Formation of key substances.

The most prevalent structural features of collagen are three.

Spiral structure. Each collagen chain is a left-handed rotating structure, with three left-handed spiral chains intertwined with each other.

Right-hand spiral. structure, with its unique triple helix structure, makes its molecular structure very stable and has a low profile.

Immunogenicity. And good.

Biocompatible.

Collagen is rich in 18 amino acids, 7 of which are necessary for human growth. Glycine accounts for 30% of collagen, proline and hydroxyproline account for about 25%, which is the highest content among various proteins, and the content of alanine and glutamic acid is also relatively high, like hydroxyproline and pyroglutamic acid are rare in other proteins, and like hydroxyl amino acids are almost non-existent in other proteins. Therefore, the nutritional value of collagen is very rich.

Also, collagen is the same.

Biotech industry.

It is also widely used in biology, medicine, health products, food, cosmetics and other fields.

Collagen is found in connective tissue with.

Elastin. and polysaccharide proteins intertwined to form a network structure", resulting in a certain.

Mechanical strength. It is support.

Human body curves. It embodies the material basis of the upright posture. As we age** and the amount of water in our muscles decreases, collagen fibers begin to shrink and elastin becomes less elastic

Dermis. "Collagen" interacts with "elastin" to form a regular network structure gradually.

Disintegrate. Finally, it leads to roughness and wrinkles.

For the average person, the collagen in the body begins to gradually lose after the age of 25. Women, in particular, lose several times faster than men due to physiological characteristics; As a result, calcium is lost. And for women around menopause, supplementation.
