A cell coating consisting of glycoproteins and proteoglycans.
Extracellular polymeric material produced by some bacteria. Term initially applied to the polysaccharide matrix excreted by epithelial cells forming a coating on the surface of epithelial tissue. General term for polysaccharide compounds outside the bacterial cell wall. Also called slime layer, EPS, or matrix polymer. ( See EPS.)
General term for polysaccharide components outside the bacterial cell wall. See also capsule and slime layer.
Inner endothelial lining of capillaries; consisting of glycoproteins and albumins forming a molecular sieve.
The glycoprotein-polysaccharide covering that surrounds many cells.
Carbohydrate-rich layer that forms the outer coat of a eucaryotic cell. Composed of the oligosaccharides linked to intrinsic plasma membrane glycoproteins and glycolipids, as well as glycoproteins and proteoglycans that have been secreted and reabsorbed onto the cell surface.
a typically loose extracellular layer of polysaccharides. The term is used most frequently of prokaryotes. However, some eukaryotes have a similar coat, e.g., Microsporidia of the family Mrazekiidae. Morris & Adams (2002).
A gelatinous polysaccharide and/or polypeptide outer covering. The glycocalyx can be identified by negative staining techniques. The glycocalyx is referred to as a capsule if it is firmly attached to the cell wall, or as a slime layer if loosely attached. This material produced by bacteria forms the structural matrix of biofilm.
extracellular polymeric substances (sticky polymers) which bacteria excrete to adhere to solid surfaces and to trap nutrients
gli-ko-CAY-lix A sticky layer of a bacterial cell wall that consists of proteins and/or polysaccharides. 446
