Study Notes
Collagen Structure and Function
- The main function of collagen in tissues is to provide strength, structure, and elasticity.
- The primary chain of collagen has a general structure consisting of Gly-X-Y repeats, where X and Y are often proline and hydroxyproline.
Tertiary Structure of Tropocollagen
- The tertiary structure of Tropocollagen is a triple helix, stabilized by hydrogen bonds, ionic interactions, and hydrophobic forces.
Collagen Fiber Formation
- The formation of collagen fibers is led by the cross-linking of Tropocollagen molecules.
Genetic Disorders
- Osteogenesis Imperfecta, also known as Brittle Bone Disease, is a genetic disorder caused by mutations in collagen genes.
- Osteogenesis Imperfecta is characterized by high fragility of bones, leading to frequent fractures.
Vitamin Deficiency
- A deficiency in Vitamin C can lead to symptoms such as small hemorrhages, tooth loss, and poor wound healing.
- Vitamin C is required for the synthesis of hydroxyproline, a crucial component of collagen.
Collagen Types and Properties
- There are several types of collagen, differing in the number of cross-links between molecules.
- The rigidity or flexibility of collagen fibers depends on the organization and cross-linking of collagen molecules.
Collagen in Tissues
- Collagen is a main component of connective tissue, providing strength, structure, and elasticity.
- Collagen is the most abundant protein in mammals.
