WebSep 12, 2024 · Many believe that hydroxyproline (Hyp) improves the structural stability of collagen molecules. In this study, for the first time, a method of building natural collagen molecular models was described. We constructed a collagen model with typical triple-helix structure and calculated the hydrogen bond energy between collagen α chains. WebThe collagen molecules themselves are made from 3 individual polypeptides or strings of amino acids. The strands wind around one another in an alpha-helix. The helix forms because of the regular amino acid sequence of the strands.
