Elastin: Elastin is a highly elastic protein in connective tissue and allows many tissues in the body to resume their shape after stretching or contracting. Elastin helps skin to return to its original position when it is poked or pinched.Tropoelastin: Tropoelastin is a water-soluble molecule with a molecular weight of approximately 72,000 daltons. Multiple tropoelastin molecules covalently bind together with crosslinks to form the protein elastin that is very prevalent in the body.DesmosineInternal elastic laminaElastaseDegenerative suspensory ligament desmitis: Degenerative Suspensory Ligament Desmitis commonly called DSLD, also known as Equine Systemic Proteoglycan Accumulation (ESPA) is a systemicCollagenDe Barsy syndrome: De Barsy syndrome is a rare autosomal recessive genetic disorder. Symptoms include cutis laxa (loose hanging skin) as well as other eye, musculoskeletal, and neurological abnormalities.Austin B. Williams: Austin Beatty Williams (October 17, 1919 – October 27, 1999) was an American carcinologist, "the acknowledged expert on and leader in studies of the systematics of eastern American decapod crustaceans".}}Moens–Korteweg equation: In biomechanics, the Moens–Korteweg equation models the relationship between wave speed or pulse wave velocity (PWV) and the incremental elastic modulus of the arterial wall or its distensibility. The equation was derived independently by Adriaan Isebree Moens and Diederik Korteweg.Dense connective tissue: Dense connective tissue, also called dense fibrous tissue, has fibers as its main matrix element.Extracellular matrixAminopropionitrileMicrofibril: A microfibril is a very fine fibril, or fiber-like strand, consisting of glycoproteins and cellulose. It is usually, but not always, used as a general term in describing the structure of protein fiber, e.
