Compare with Definitions
Glucosamine
Glucosamine (C6H13NO5) 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.
Glutamine
Glutamine (symbol Gln or Q) is an α-amino acid that is used in the biosynthesis of proteins. Its side chain is similar to that of glutamic acid, except the carboxylic acid group is replaced by an amide.
Glucosamine
An amino derivative of glucose, C6H13NO5, in which an amino group replaces a hydroxyl group. It is a component of many polysaccharides and the basic structural unit of chitin, and is used as an over-the-counter dietary supplement alone or in combination with chondroitin for treatment of joint pain in arthritis.
Glutamine
A nonessential amino acid, C5H10N2O3, occurring widely in plant and animal tissue and proteins and produced commercially for use in medicine and biochemical research.
Glucosamine
(biochemistry) An amino derivative of glucose that is a component of polysaccharides such as chitin; it is marketed as a dietary supplement supposedly to reduce the symptoms of arthritis.
