Type I and Type II Collagen Structure. Fibrillar collagen consists of three alpha (α)-chains (type I collagen: two α1-chain and one α2-chain and type II collagen: three α1-chains) that self-assemble into a left-handed triple helix structure. Individual collagen triple helixes are termed tropocollagen. The triple helix chains are ...
