Collagen is the most abundant protein in animals, accounting for more than 30% of the total protein in the human body. It belongs to insoluble fibrous proteins and is also a type of extracellular matrix. Collagen can be extracted from different tissues of animals in different types, and its functions and effects are also different. The collagen that can dissolve during extraction is usually procollagen.
So far, there are more than twenty types of collagen in the human body. Different types of collagen have different molecular structures and immunological characteristics. According to tissue classification, they can be divided into three categories:
The first category: interstitial collagens type I and III, mainly found in skin and tendons, etc., are collagens between cells with strong tensile strength. Type II collagen is produced by chondrocytes.
The second category: basement membrane collagens type IV and VII are basement membrane collagens, mainly found in organs.
The third category: cartilage collagens type IX and XI are trace collagens in cartilage related to cartilage formation.
From a structural perspective, collagen has a unique molecular structure. Under an electron microscope, three molecules present a helical structure with polymorphism. The amino acid composition of collagen peptide chains is unique, with glycine content at one-third, proline and hydroxyproline each accounting for 10%. Hydroxyproline is only found in collagen in animal tissues. The conversion rate of collagen in the skin is generally slow. In children's skin, type III is predominant, while in adulthood, type I is dominant. As age increases, cross-linked tendons increase day by day, collagen fibers become tighter, and this is related to skin aging and stiffness, leading to skin relaxation.
From the biological role of collagen, collagen has the highest content in the extracellular matrix (skin), the greatest rigidity and tensile strength, and is the framework structure of the extracellular matrix. Additionally, other components in the extracellular matrix can bind separately with collagen, forming a unified structure and function. At the same time, various types of collagen have certain selectivity when binding with extracellular matrix components.
A large number of experimental studies have proven that as women age, wrinkles, pigmentation, dullness, and other skin problems are caused by the continuous decomposition and rapid loss of collagen in the dermis. Using Yishengmei Collagen Powder can replenish sufficient collagen. "Yishengmei Collagen" is suitable for every adult who desires youth and whiteness.
