WebStructure. Collagen is formed from three polypeptide chains closely held together by hydrogen bonds to form a triple helix (known as tropocollagen) Each polypeptide chain is a helix shape (but not α-helix as the chain is not as tightly wound) and contains about 1000 amino acids with glycine, proline and hydroxyproline being the most common. WebIn this structure, the researchers placed a larger alanine amino acid in the position normally occupied by glycine, showing that it crowds the neighboring chains. The collagen helix shown on the right contains a …

Atelocollagen, prepared by hydrolyzing collagen by acid treatment, dissolves in an acidic aqueous solution as the collagen fibrils dissociate, while maintaining the triple-helical structure. joan elizabeth clark
