Collagen fibrils bonds
WebIn molecular biology, the collagen triple helix or type-2 helix is the main secondary structure of various types of fibrous collagen, including type I collagen. In 1954, Ramachandran & Kartha (13, 14) advanced a structure for the collagen triple helix on the basis of fiber diffraction data. WebJun 19, 2024 · Pathological biomineralization can also occur outside collagen fibrils; such formation outside the collagen fibrils is known as extrafibrillar mineralization [ 65 ]. In order to understand aberrant biomineralization, it is crucial to understand the mechanisms by which collagen is mineralized and the related pathways.
