A component of type I collagen called the pro-α1 (I) chain is produced from the COL1A1 gene. Collagens begin as rope-like procollagen molecules that are each made up of three chains. Type I collagen is composed of two pro-α1 (I) chains and one pro-α2 (I) chain (which is ...
Web1 day ago · The smaller fibril strains indicate that the interfibrillar gliding due to the watery layer has a more pronounced effect than a reduction of the collagen molecule stiffness (Figure 4). This watery layer might reduce the binding interactions between fibrils and matrix leading to a higher mobility of the fibrils within the extrafibrillar matrix. 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.
