Collagen is an important protein, which occupies an important position in human body.
Root According to its source and structure, collagen can be divided into many types.
This article will start from collagen To introduce the characteristics and functions of these types.
1. Type I collagen
Type I collagen is the most common type of collagen, which points out the collagen egg in human body Quantity, more than 90%.
It mainly exists in skin, bone, muscle, tendon, ligament and other groups In weaving, it has supporting and protecting functions.
The molecular structure of type I collagen is triple helix Shape, with strong tensile strength and stability.
2. Type II collagen
Type II collagen mainly exists in cartilage and eyeball, which maintains the structure of cartilage and eyeball.
Important ingredients. Its molecular structure is spiral, with good elasticity and toughness.
Type II Lack of collagen can lead to cartilage degeneration and eye diseases.
3. Type Ⅲ collagen
Type Ⅲ collagen mainly exists in blood vessels, muscles, liver, kidney and other tissues, and has
The role of maintaining organizational structure and elasticity. Its molecular structure is fibrous and has good
Tensile and elastic. The lack of type Ⅲ collagen can lead to tissue relaxation and brittleness.
4. Type IV collagen
Type IV collagen mainly exists in the basement membrane, which is the weight to maintain the structure of cells and basement membrane.
Ingredients. Its molecular structure is reticular and has good filtering and supporting functions. Type IV
Lack of collagen can lead to basement membrane destruction and cell dysfunction.
5. Type V collagen
Type V collagen mainly exists in skin, muscle, liver, kidney and other tissues, which is vitamin
Important components of organizational structure and elasticity. Its molecular structure is fibrous and has good features
The tensile property and elasticity. Lack of Type V collagen can lead to tissue relaxation and brittleness.
The classification of collagen is based on its source and structure. Different types of collagen eggs
White has different functions and importance in human body. Understand the classification and function of collagen,
It helps us to better protect and maintain our health.
