GO Term : GO:0042340 keratan sulfate catabolic process GO

Namespace:  biological_process Obsolete:  false
description  The chemical reactions and pathways resulting in the breakdown of keratan sulfate, a glycosaminoglycan with repeat units consisting of beta-1,4-linked D-galactopyranosyl-beta-(1,4)-N-acetyl-D-glucosamine 6-sulfate and with variable amounts of fucose, sialic acid and mannose units; keratan sulfate chains are covalently linked by a glycosidic attachment through the trisaccharide galactosyl-galactosyl-xylose to peptidyl-threonine or serine residues.

GO:0008152 metabolic process The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
GO:0044237 cellular metabolic process The chemical reactions and pathways by which individual cells transform chemical substances.
GO:0006807 nitrogen compound metabolic process The chemical reactions and pathways involving organic or inorganic compounds that contain nitrogen, including (but not limited to) nitrogen fixation, nitrification, denitrification, assimilatory/dissimilatory nitrate reduction and the interconversion of nitrogenous organic matter and ammonium.
GO:0071704 organic substance metabolic process The chemical reactions and pathways involving an organic substance, any molecular entity containing carbon.
GO:0006082 organic acid metabolic process The chemical reactions and pathways involving organic acids, any acidic compound containing carbon in covalent linkage.

GO:0030203 glycosaminoglycan metabolic process The chemical reactions and pathways involving glycosaminoglycans, any one of a group of polysaccharides that contain amino sugars. Formerly known as mucopolysaccharides, they include hyaluronic acid and chondroitin, which provide lubrication in joints and form part of the matrix of cartilage. The three-dimensional structure of these molecules enables them to trap water, which forms a gel and gives glycosaminoglycans their elastic properties.
