章节大纲

    • 1. Fibril: the fiber of collagen molecules


      The form of collagen found inside the body of animals. The molecules are arranged regularly to form a fiber.

      It serves as a cell scaffold, creating a three-dimensional structure of the tissue.

      Used as a scaffold for tissue engineering.

    • 2. Molecules (collagen molecules): three spiral peptide-bond molecules


      The form of collagen found upon extraction.

      They have strong cell adhesion and are used in cell culture.

      In addition, they have strong water retention and are also used in cosmetics.

    • 3. Gelatin: peptide-bond polymer


      Collagen molecules that are unraveled by heating

      In addition to being used as a gelling agent for food, they are used in cell culture.

    • 4. Peptide: amino-acid peptide-bond small molecule


      A low molecular weight product obtained by hydrolyzing gelatin.

      Because of its various cell activities, it is used in functional cosmetics that activate skin cells.

      It is also used in health foods due to its high absorbency.
