Apr 1, 2004 · Here, we describe the isolation and characterisation of carboxy-terminal telopeptide structures of type I collagen from human mineralised bone. Analysis of the collagen cross-links within the purified structures indicated the presence of trivalent ICTP structures, divalently cross-linked peptides and uncross-linked telopeptide chains. In contrast to chemical cross-links, physical cross-links are formed by weaker interactions. For example, sodium alginate gels upon exposure to calcium ions, which form ionic bonds that bridge between alginate chains.
