proteo-|prəʊtiːəʊ-|
comb. form of protein; proteoˈclastic a. [see clastic a.] = proteolytic a.; proteoglycan |-ˈglaɪkæn| (see quot. 1969); proteoˈlipid, -ide, a complex that contains protein and lipid moieties and is insoluble in aqueous media but soluble in organic solvents; cf. lipoprotein s.v. lipo-. Also proteolysis, etc.

1969Hascall & Sajdera in Jrnl. Biol. Chem. CXLIV. 2384/2 We refer to this fraction, which is a basic building block for the cartilage matrix, as proteoglycan subunit. Because of the selectivity of the techniques used in its purification we presume that it contains only covalently bound protein. The second component is a glyco⁓protein fraction. [Note] The term ‘proteoglycan’ is used to describe macromolecules which consist primarily of polysaccharide which is presumed to be bound covalently to the small amount of protein present. ‘Glycoprotein’ is used to indicate a macromolecule which is primarily protein, but which contains covalently bound saccharide. 1974Sci. Amer. May 67/1 It does appear, however, that the wet surfactants on the ocean, which are known to be glycoproteins and proteoglycans, are reasonably good carriers of phosphate, of various organic molecules, of the scarcer ions of seawater and of heavy metals. 1977Lancet 4 June 1190/2 The major proteins of cartilage are proteoglycan..and type-II collagen.
