Amucoprotein is a glycoprotein composed primarily of mucopolysaccharides. Mucoproteins can be found throughout the body, including the gastrointestinal tract, reproductive organs, airways, and the synovial fluid of the knees. They are called mucoproteins because the carbohydrate quantity is more than 4% unlike glycoproteins where the carbohydrate quantity is less than 4%. Mucoprotein is produced in the cecum of the gastrointestinal tract. During gallbladder cancer, mucoprotein is over expressed. Sustaining a brain injury will lead to decreased mucoprotein production. The result is an alteration of gut microbiota as seen in mice.
Mucoproteins are the proteins that are the building blocks of mucus, which is a protective barrier to the epithelia of cells. It is semipermeable, so it acts as a barrier to most bacteria and pathogens, while allowing for the uptake of nutrients, water, and hormones.[1]
Mucoproteins are composed of o-linked carbohydrates as well as highly glycosylated proteins, which are held together by disulfide bonds.[2] The viscosity of the mucus depends on the strength of the disulfide bonds. When these disulfide bonds are broken, the viscosity of the mucus secretions is reduced.
Mucolytic medications will break through the disulfide bonds and lower the viscosity of the mucus, thus allowing the hypersecreted mucus to be more manageable. A hypersectretion of mucus is often a symptom of pulmonary diseasesorrespiratory infections.[3]
There are two subgroups in mycolytic medications and each one works differently to control the hypersecreted mucus.
