Describe the structure of a collagen molecule
WebThe structure is stabilised by hydrogen bonds between the backbone amide of a Gly residue and the backbone carbonyl of residue X, where the sequence is represented by a repeat of -Gly-X-Y-. Collagen I, which constitutes 90% of the collagen in a mammal, consists of a heterotrimer where 2 of the alpha-chains are identical. WebThe interaction of collagen, whose structure is strongly influenced by the interaction with water molecules, can be studied following the behavior of water diffusion by low-resolution 1H NMR experiments. The present study is addressed to study the collagen stability as a function of pH, ionic strength, and phenolic antioxidants like catechin.
