What is mucine.?

Mucin is a type of glycoprotein that is found in various bodily fluids and tissues, such as saliva, mucus, and gastrointestinal lining. It is composed of a protein backbone with branches of sugars known as oligosaccharides attached. Mucins are known for their high viscosity and their ability to form gels, which is important for lubrication, protection, and barrier function in the body. There are several different types of mucins with distinct functions, and alterations in mucin expression or structure have been associated with numerous diseases such as cancer, cystic fibrosis, and inflammatory bowel disease.
