Collagen is the most important scleroprotein in the bodies of humans and animals. It consists of polypeptide chains folded into a triple-helical conformation, ensuring cohesion, elasticity, and regeneration of all our connective tissue.
Collagen hold us together. It makes up to 30% of the protein in the body, and up to 70% of the protein in the skin.
Scientific studies have identified at least 28 different types of collagen throughout the body, with the most abundant being type I, II, and III.
The most common types of collagen are:
- Type I: Over 90% of collagen in the human body; skin, tendon, vasculature ligature, organs, and bone.
- Type II: Cartilage.
- Type III: Reticular and commonly found alongside Type I.
- Type IV: Basal lamina.
- Type V: Cell surfaces, hair, and placenta.
