mucopolysaccharide

 [mu″ko-pol″ĭ-sak´ah-rīd]
a group of polysaccharides that contain hexosamine, that may or may not be combined with protein and that, dispersed in water, form many of the mucins.

mu·co·pol·y·sac·cha·ride

(myū'kō-pol'ē-sak'ă-rīd),
General term for a protein-polysaccharide complex obtained from proteoglycans and containing as much as 95% polysaccharide; mucopolysaccharides include the blood group substances. A more modern term is glycosaminoglycan, because all of the known six classes contain major amounts of d-glucosamine and d-galactosamine.

mucopolysaccharide

/mu·co·poly·sac·cha·ride/ (-sak´ah-rīd)
2. any polysaccharide with high hexosamine content, including the glycosaminoglycans and also neutral polysaccharides such as chitin.

mucopolysaccharide

[myo̅o̅′kōpol′ēsak′ərīd]
Etymology: L, mucus + Gk, polys, many, sakcharon, sugar
a polysaccharide containing hexosamine and sometimes occurring with protein, such as mucins.

mu·co·pol·y·sac·cha·ride

(myū'kō-pol'ē-sak'ă-rīd)
General term for a protein-polysaccharide complex obtained from proteoglycans and containing as much as 95% polysaccharide; mucopolysaccharides include the blood group substances. A more current term is glycosaminoglycan.

mucopolysaccharide

POLYSACCHARIDEs containing amino sugars or that are polymers of MONOSACCHARIDES in which one of the -OH groups is replaced by an NH2 group. Mucopolysaccharides are important structural materials in the body forming the ground substance of many connective tissues in which fibrous proteins are embedded. Now more commonly called glycosaminoglycans.

mucopolysaccharide

any polysaccharide, such as hyaluronic acid or heparin, that contains either an amino sugar or a derivative. Also called glycosaminoglycans (GAGs). Often GAGs are found covalently bound to core proteins forming proteoglycans.

Mucopolysaccharide

A complex molecule made of smaller sugar molecules strung together to form a chain. Found in mucous secretions and intercellular spaces.

mucopolysaccharide

a group of polysaccharides that contain hexosamine, which may or may not be combined with protein; when dispersed in water, mucopolysaccharides form many of the mucins.

acid mucopolysaccharide
the amorphous, PAS-positive intercellular substance of most connective tissue. Formed by fibroblasts and osteoblasts.

Patient discussion about mucopolysaccharide

Q. Does GAG really help? My mother suffers from osteoarthritis, and after taking a lot of pain-killers someone offered us to try glycosaminoglycans. Does it really help? It’s quite expensive….

A. As far as I know it wasn’t proved in well-controlled trials to benefit the patients over placebo, so if it’s a consideration for you, I’m not sure it justifies the price. However, I’m only a lay-man, so consulting a professional (i.e. a doctor) is better.
