mu·cin
(myū'sin),The hydrated form of mucinogen, a secretion containing carbohydrate-rich glycoproteins such as those 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, especially mucous connective tissue, is soluble in alkaline water, and is precipitated by acetic acid; mucins lubricate and protect body cavity linings.

mucin
Glycoprotein, 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. See precorneal film; keratoconjunctivitis sicca; break-up time test; xerophthalmia.
