Human types

Over 90% of the collagen in the human body is type I collagen. However, as of 2011, 28 types of human collagen have been identified, described, and divided into several groups according to the structure they form. All of the types contain at least one triple helix. The number of types shows collagen's diverse functionality.

• Fibrillar (Type I, II, III, V, XI)
• Non-fibrillar
  • FACIT (Fibril Associated Collagens with Interrupted Triple Helices) (Type IX, XII, XIV, XIX, XXI)
  • Short chain (Type VIII, X)
  • Basement membrane (Type IV)
  • Multiplexin (Multiple Triple Helix domains with Interruptions) (Type XV, XVIII)
  • MACIT (Membrane Associated Collagens with Interrupted Triple Helices) (Type XIII, XVII)
  • Microfibril forming (Type VI)
  • Anchoring fibrils (Type VII)
