Collagen

Types of Collagen and Their Function

Collagen molecules are formed from amino acids, principally proline, glycine, and hydroxyproline. These amino acids are arranged in a triple helix structure, and their synthesis in the body requires nutrients such as vitamin C, zinc, copper, and manganese. Collagen also aids in forming fibroblasts in the dermis, playing a role in replacing dead skin cells, protecting organs, assisting in blood clotting, and offering strength and elasticity to the skin.

There are at least 28 known types of collagen. Each type is unique and serves independent roles in the body. Here is a detailed look at the predominant types of collagen found in the body and their primary function:

• Type I Collagen:
  • Location: Found in skin, bones, tendons, and ligaments.
  • Function: Provides structure and strength. It is the most abundant collagen type, making up about 90% of your body’s collagen.

• Type II Collagen:
  • Location: Found in cartilage.
  • Function: Provides joint support.

• Type III Collagen:
  • Location: Found in muscles, organs, and arteries.
  • Function: Supports the structure of muscles, organs, and the cardiovascular system.

• Type IV Collagen:
  • Location: Found in layers of the skin and in the basement membrane of epithelial cells.
  • Function: Helps form the basal lamina, which supports cells and organs.

• Type V Collagen:
  • Location: Found in the cornea of the eyes, some skin layers, and the placenta’s tissue.
  • Function: Plays roles in the visibility of the cornea, skin health, and functioning of the placenta during pregnancy.
