Triple Helical Structure of Collagen
Collagen is a protein that is found abundantly in the extracellular matrix (ECM) of various tissues and organs in the body. It is a fibrous protein that provides structural support to the tissues and helps in maintaining their shape and integrity. The triple helical structure of collagen was discovered by G.N. Ramachandran in 1951.
What is a Triple Helix?
A triple helix is a three-stranded helix in which three polypeptide chains are coiled around each other in a rope-like structure. The triple helix is stabilized by hydrogen bonds between the amino acid residues of the three chains.
Structure of Collagen
Collagen is composed of three polypeptide chains, each of which is a long, slender molecule containing repeated sequences of amino acids. These chains are called alpha chains and are arranged in a triple helix, which gives collagen its strength and stability.
The amino acid composition of collagen is unique, with glycine, proline, and hydroxyproline being the most abundant amino acids. Glycine is found at every third position in the chain, which allows the chains to pack tightly together in the triple helix.
Function of Collagen
Collagen is a major structural protein in the body and is essential for the formation and maintenance of various tissues such as bone, cartilage, skin, and tendons. It provides strength and stability to these tissues and helps in maintaining their shape and integrity.
Collagen also plays a role in wound healing, as it forms a scaffold for the migration of cells and promotes the deposition of new tissue.
Conclusion
In conclusion, the triple helical structure of collagen was discovered by G.N. Ramachandran in 1951. This structure is composed of three polypeptide chains arranged in a rope-like structure, which provides strength and stability to the protein. Collagen is a major structural protein in the body and is essential for the formation and maintenance of various tissues.
