Final answer:
The amino acid composition of collagen is reflected in its high content of glycine, proline, and hydroxyproline. These amino acids contribute to the formation of the collagen triple helix structure and provide rigidity and strength to the molecule.
Step-by-step explanation:
The high content of glycine, proline, and hydroxyproline in collagen is reflected in its amino acid composition. The amino acid composition of collagen is reflected in its high content of glycine, proline, and hydroxyproline. These amino acids contribute to the formation of the collagen triple helix structure and provide rigidity and strength to the molecule.
Collagen is made up of repeat units of Gly-X-Y, where X is usually proline and Y is generally hydroxyproline. Glycine, being the smallest amino acid, is found in every third position in the polypeptide chain, enabling the formation of the collagen triple helix. Proline and hydroxyproline contribute to the rigidity and strength of the collagen molecule.
