Definitions for "Glycosaminoglycans"
Large polysaccharide molecules of the extracellular matrix, which often combine with proteins to form proteoglycans.
(GAGs). Polysaccharides that comprise repeating disaccharide units of amino-sugar derivatives that are covalently bonded to proteins to function as proteoglycans. Four types of GAG exist according to their sugar residues, and sulphate group numbers and location: chondroitan sulphate and dermatan sulphate; heparin sulphate and heparin; keratan sulphate and hyaluronan.
Large molecules found in the dermis that contains sugar and protein helping to maintain moisture levels within the skin.
a marine mucopolysaccharide that provides a protective, moisturized film that retains the water in the corneous layer, while preserving the gaseous exchanges that are essential for the skin to "live". In clinical studies, this material produces a tightening effect, and soft and smooth after-feel.
