1Biochemistry A crystalline compound which occurs widely in connective tissue, especially as a component of chitin.
A glucose derivative containing an amino group; chemical formula: C₆H₁₃NO₅
‘In addition, experiments were conducted at sea to measure the growth of heterotrophic bacteria in response to amendments of amino acids, protein, N-acetyl glucosamine, and chitin.’
‘An example of recurrent mutation in human beings is the ABO blood group, where types A and B are functional alleles that control enzymes that link glucosamine or n-acetyl glucosamine to a common precursor.’
‘Glutamine is an energy source for enterocytes of the small intestine, helps form nicotinamide for energy transfers and glucosamine for connective tissue, and contributes to purine and pyrimidine nucleotides.’
‘Once it reaches the chondrocytes, the cells that produce cartilage, the glucosamine is incorporated.’
‘Estimation of the absolute configuration of glucosamine in lipids A was established as given elsewhere [39, 40].’
1.1A synthesized form of glucosamine, taken to relieve arthritis pain.
‘Others will have to rely on acetaminophen or dietary supplements such as glucosamine, ginger, turmeric or boswellia.’
‘Some evidence suggests that the dietary supplement glucosamine probably improves osteoarthritis symptoms.’
‘Some find dietary supplements such as glucosamine and chondroitin helpful.’
‘Examples of herbs include ginseng, ginkgo and echinacea, while examples of other dietary supplements include selenium, glucosamine and SAMe.’
