A single collagen molecule, tropocollagen, is used to make up larger collagen aggregates, such as fibrils. It is approximately 300 nm long and 1.5 nm in diameter, and it is made up of three polypeptide strands (called alpha peptides, see step 2), each of which has the conformation of a left-handed helix – this should not be confused with the right-handed alpha helix. These three left-han… 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.
