A protein complex consisting of three collagen chains assembled into a left-handed triple helix. These trimers typically assemble into higher order structures. [GOC:dos, GOC:mah, ISBN:0721639976, PMID:19693541, PMID:21421911]
Collagen trimers are complex structures formed by the assembly of three individual collagen polypeptide chains, known as alpha chains. Each alpha chain is composed of a repeating sequence of amino acids, predominantly glycine, proline, and hydroxyproline, giving rise to a characteristic triple helix structure. The three alpha chains intertwine to form a right-handed superhelix, stabilized by numerous hydrogen bonds and van der Waals interactions. The assembly of collagen trimers into higher-order structures, such as fibrils, is facilitated by interactions between specific amino acid residues, particularly lysine and hydroxylysine. This process involves covalent cross-linking, which strengthens the collagen fibrils and provides tensile strength. The cellular component of collagen trimers can be described as a complex network of intertwined alpha chains, stabilized by intermolecular forces and covalent cross-links. This network forms the fundamental building block for collagen fibrils, which are the primary structural components of various tissues, including connective tissues, bones, and cartilage. The specific amino acid composition and the unique triple helical structure of collagen trimers contribute to their remarkable strength, flexibility, and resilience.'
