n. any of a class of mucoproteins abundant in saliva, gastric juices, and other mucous secretions of the body. [1825–35; < French mucine; see mucus, -in1] mu•ci•nous (ˈmyu sə nəs) adj. Thesaurus| Noun | 1. | mucin - a nitrogenous substance found in mucous secretions; a lubricant that protects body surfacesmucous secretion, mucus - protective secretion of the mucus membranes; in the gut it lubricates the passage of food and protects the epithelial cells; in the nose and throat and lungs it can make it difficult for bacteria to penetrate the body through the epitheliumglycoprotein - a conjugated protein having a carbohydrate component |

mu′cin·ous adj.mu·cin (myū'sin) A secretion containing carbohydrate-rich glycoproteins such as that from the goblet cells of the intestine, the submaxillary glands, and other mucous glandular cells; it is also present in the ground substance of connective tissue. mucin A glycoprotein that is the main constituent of MUCUS. The term is also used as a generic name for the substance used as a drug formulated with xylitol as artificial saliva under the brand name is Saliva Orthana.mucin a MUCOPROTEIN that forms MUCUS when in solution.MucinA protein in saliva that combines with sugars in the mouth to form plaque.Mentioned in: Tooth DecaymucinGlycoprotein, rich in carbohydrates, produced by the goblet cells and the subsurface vesicles of the conjunctiva which forms the basis of the mucous layer of the precorneal film. Mucin and the secreted glycocalyx (which consists of glycoproteins) are adsorbed by the epithelium of the cornea to convert it from a hydrophobic into a wettable hydrophilic surface. A deficiency in the production of mucin leads to an abnormally short precorneal film break-up time and to desiccation of the ocular surface. In addition, the mucous layer prevents microbial invasion of the cornea. In some contact lens wearers (especially of silicone hydrogel lenses) collapsed mucin, as well as lipids and tear proteins, accumulate behind the lens and form small, discrete spheres (called mucin balls or mucin plugs). These mucin balls cause neither discomfort nor loss of vision.
