A nitrogenous substance, somewhat resembling albumin, which forms the chemical basis of elastic tissue. It is very insoluble in most fluids, but is gradually dissolved when digested with either pepsin or trypsin.
Fibers found in the dermis (middle layer of the skin) that give skin it's elastic qualities by stretching and returning to their original size and shape. UV exposure can destroy elastin causing the skin to sag and form wrinkles.
Protein component of elastic connective tissue, present in artery walls, skin and intestinal walls. The elastin protein chain is particularly flexible and will return to its original shape after being stretched.
Protein similar in structure to collagen and is chief constituent of elastic fibers embedded in extracellular matrix. The fibrous components form an elastic network to uniformly maintain the resilience and elastic properties to local tissue requirements. Back to glossary index
coiling and recoiling protein, like a spring, within elastic fibers of connective tissue accounting for the elasticity of structures such the skin, blood vessels, heart, lungs, intestines, tendons, and ligaments; works with collagen-elastin provides elasticity, collagen provides rigidity
a major fibrous mucoprotein of skin, lungs and blood vessels providing these tissues with resilient, elastic characteristics. It is the major connective tissue found in elastic structures such as blood vessels.
Major component of skin that gives it flexibility. Sun damage causes elastin in skin to deteriorate. Elastin can be derived from both plant and animal sources and is used in cosmetics as a good water-binding agent.
A protein that coil and recoils like a spring within the elastic fibers of connective tissue and accounts for the elasticity of structures such the skin, blood vessels, heart, lungs, intestines, tendons, and ligaments. Elastin functions in connective tissue together with collagen. Whereas elastin provides elasticity, collagen provides rigidity to connective tissue. Elastin is normally no longer made after puberty and aging begins. Also called elasticin.
Elastin is our body's structural protein that gives elasticity to our tissues and organs. Elastin is found predominantly in the walls of our arteries, in our lungs, intestines, and skin, as well as in other elastic tissues. It functions in connective tissue in partnership with collagen. Whereas collagen provides rigidity, elastin is the protein which allows the connective tissues in our blood vessels and heart tissues, for example, to stretch and then recoil to their original positions.
Highly elastic albumin-like protein fiber found in the dermis, blood vessels, capillaries and other elastic tissue in the body. Allows skin to stretch then return to normal when we are young; contributes to sagging skin as the quality of elastin is reduced with age.
Elastin, is a protein in connective tissue that is elastic 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.
