Collagen is the major structural protein for extracellular matrix, and it is also the most abundant protein in vertebrates. ECM consists of protein fibers and ground substance collagen's macromolecular structure consists of 3- coiled polypeptides called alpha chains, which are left-handed polypeptide helices and wind around right-handed triple helix. It also has 3.3 amino acid residue per turn. ECM consists of protein fibers and ground substance, which collagen's macromolecular structure would help leading it to function. Collagen's biophysical characteristics in extracellular matrix are acellular component and tissue and organs used collagen in cell morphogenesis and differentiation, which would help for maintaining homeostasis. Collagen also helps in glycosylation. EMC is usually secreted by the connective tissue cells and determines the tissue qualities. Formation of tropocollagen as it is fundamental unit of collagen and it is secreted in extracellular space, which helps in aggregation of fibrils. As collagen is a large family of proteins and it contains about 19 different members. The amino acid sequence is alpha chain and consist of repeating tripeptide unit as glycine, Proline and Hydroxyproline. The hydroxylation is carried out during post translational modifications of alpha chains by two enzymes prolyl hydroxylase and ysyl hydroxylase. So, by this its molecular composition impact these characteristics.
