  2. Glucosamine - Wikipedia

    en.wikipedia.org/wiki/Glucosamine

    Glucosamine (C 6 H 13 NO 5) is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids. Glucosamine is part of the structure of two polysaccharides, chitosan and chitin. Glucosamine is one of the most abundant monosaccharides. [2] Produced commercially by the hydrolysis of shellfish exoskeletons ...

  3. Clinical trials on glucosamine and chondroitin - Wikipedia

    en.wikipedia.org/wiki/Clinical_trials_on...

    The authors of the study analyzed the moderate-to-severe pain group and found that in this group, the combination of glucosamine and chondroitin was more effective at providing pain relief than the positive control with 79% of the glucosamine group reporting at least a 20% reduction in pain compared to 70% for celecoxib and only 54% reporting a ...

  4. Glycosaminoglycan - Wikipedia

    en.wikipedia.org/wiki/Glycosaminoglycan

    Glycosaminoglycans[1] (GAGs) or mucopolysaccharides[2] are long, linear polysaccharides consisting of repeating disaccharide units (i.e. two-sugar units). The repeating two-sugar unit consists of a uronic sugar and an amino sugar, except in the case of the sulfated glycosaminoglycan keratan, where, in place of the uronic sugar there is a ...

  5. N-Acetylglucosamine - Wikipedia

    en.wikipedia.org/wiki/N-Acetylglucosamine

    N-Acetylglucosamine (GlcNAc) is an amide derivative of the monosaccharide glucose. It is a secondary amide between glucosamine and acetic acid. It is significant in several biological systems. It is part of a biopolymer in the bacterial cell wall, which is built from alternating units of GlcNAc and N -acetylmuramic acid (MurNAc), cross-linked ...

  6. Uridine diphosphate N-acetylglucosamine - Wikipedia

    en.wikipedia.org/wiki/Uridine_diphosphate_N...

    Uridine diphosphate N-acetylglucosamine or UDP-GlcNAc is a nucleotide sugar and a coenzyme in metabolism. It is used by glycosyltransferases to transfer N -acetylglucosamine residues to substrates. D -Glucosamine is made naturally in the form of glucosamine-6-phosphate, and is the biochemical precursor of all nitrogen-containing sugars. [1]

  7. Chondroitin sulfate - Wikipedia

    en.wikipedia.org/wiki/Chondroitin_sulfate

    Chondroitin sulfate is an important structural component of cartilage, [2] and provides much of its resistance to compression. [3] Along with glucosamine, chondroitin sulfate has become a widely used dietary supplement for treatment of osteoarthritis, although large clinical trials failed to demonstrate any symptomatic benefit of chondroitin.
