[f. muco- + polysaccharide.]

1938K. Meyer in Cold Spring Harbor Symp. Quant. Biol. VI. 91/1 The mucopolysaccharides of our terminology were formerly included as mucins and as mucoids in the group of conjugated proteins. They occur in nature either as free polysaccharides or as protein salts. 1947Physiol. Rev. XXVII. 335 Hyaluronic acid is a mucopolysaccharide acid which in animal tissues seems to bind water in interstitial spaces. It further holds cells together in a jelly-like matrix and serves as a lubricant and shock-absorber in joints. 1963R. W. Jeanloz in Florkin & Stotz Comprehensive Biochem. V. vii. 262 Two groups of substances, which in the past had been described under the name of mucopolysaccharide, namely the glycoproteins and the glycolipids, will be discussed in other chapters. 1967[see mucoid n.]. 1971J. Z. Young Introd. Study Man xl. 584 There is polymorphic variation in certain mucopolysaccharide constituents of the red cells of the blood. |
