Kollagenet
Kollagenet is a family of structurally related proteins that form the main component of connective tissues in animals. It provides tensile strength and structural support in tendons, bones, skin, cartilage, blood vessels, and organs. Kollagen proteins are produced by a wide range of cells, including fibroblasts, chondrocytes, and osteoblasts, and are secreted into the extracellular matrix where they assemble into fibrils and networks.
Most kollagen types share a common triple-helix structure formed by three polypeptide chains rich in glycine,
Biosynthesis begins with the production of procollagen inside cells, followed by secretion, extracellular processing of propeptides,
Dietary kollagen and collagen-derived supplements are marketed for joint and skin health, though evidence on their
