Unformatted text preview: g block on which collagens are based? What is an alpha- chain? Describe the structure of the collagen triple helix. How many polypeptides are involved? What tripeptide sequence comprises most of the sequence of a collagen polypeptide? How do the amino acids in this tripeptide contribute to the structure of the collagen triple helix (e.g. what is the function of the Pro and HO- Pro? What is the function of the Gly. How do the R groups of these amino acids contribute to the formation of the triple helix). What covalent bond links the three polypeptides together? What are the three main groups of collagen isoforms? Describe their basic structures and how they differ from one another. Describe the functions of the three different groups of collagen isoforms and give examples of where each is found. How does the staggered struct...
