What is and why is it important❓❓
Collagen is a type of protein. In fact, it’s the most abundant structural protein in animals. A structural protein is one that makes up the structure or framework of your cells and tissues.
There are 2⃣8⃣ known types of collagen, with type I collagen accounting for 9⃣0⃣% of the collagen in the human body.
Collagen is composed mainly of the amino acids glycine, proline, and hydroxyproline. These amino acids form three strands, which make up the triple-helix structure characteristic of collagen.
Collagen is found in connective tissue, skin, tendons, bones, and cartilage. It provides structural support to tissues and plays important roles in cellular processes:
✅ tissue repair
✅ immune response
✅ cellular communication
✅ cellular migration, a process necessary for tissue maintenance
Connective tissue cells called fibroblasts produce and maintain collagen. As people grow older, their collagen becomes fragmented, fibroblast function becomes impaired, and collagen production slows.
These changes, along with the loss of another key structural protein called elastin, lead to signs of aging such as sagging skin and wrinkles.
