Collagen and elastin synthesis

Collagen and elastin synthesis is a fundamental process occurring primarily in **fibroblasts** of connective tissue, responsible for producing the proteins collagen (which provides tensile strength) and elastin (which confers elasticity)[2][4][5][6]. Collagen synthesis involves translation of alpha chains, post-translational modification (hydroxylation, glycosylation), triple-helix assembly, secretion, and extracellular crosslinking[1][3]. Elastin is produced as tropoelastin, which aggregates and is crosslinked extracellularly, forming elastic fibers able to stretch and recoil[4][5]. Disruption of these processes underlies skin aging, fibrotic diseases, certain genetic syndromes, and impacts other tissue systems, such as cardiovascular and pulmonary tissues. The synthesis of both proteins is highly regulated and involves key enzymes (e.g., lysyl oxidase, prolyl hydroxylase) and cofactors (notably vitamin C), and their breakdown is mediated by matrix metalloproteinases[1][3][6]. Drugs and supplements may affect these pathways, but "collagen and elastin synthesis" itself is not a specific target; rather, individual enzymes, receptors, or pathways involved in the regulation may serve as true therapeutic targets.
