mucoitin Biochem.
(mjuːˈkəʊɪtɪn)
[f. mucin + -oitin, after chondroitin.]
A supposed mucopolysaccharide, now generally considered to be a mixture, occurring in combination with sulphuric acid in the mucin of pigs' stomachs, the cornea, and elsewhere. So mucoitinsulphuric acid.
| 1916 Levene & López-Suárez in Jrnl. Biol. Chem. XXV. 513 Further work on mucoitin sulfuric acid (as we propose to name this substance) is now in progress. 1925 P. A. Levene Hexosamines ii. iii. 85 A considerable part of the sulphuric acid radicle had been removed in the process of preparation, so that it was possible to determine the properties of mucoitin and of mucoitin sulphuric acid in the same sample. 1925 [see chondroitin]. 1964 Brimacombe & Webber Mucopolysaccharides vi. 142 It seems likely that the material originally designated as mucoitin sulphate contained hyaluronic acid admixed with sulphated mucopolysaccharides containing 2-amino-2-deoxy-d-glucose residues. 1967 Chem. Abstr. LXVI. 9649/1 The chondroitinsulfuric acid and mucoitinsulfuric acid contents were higher in the umbilical cord and myxoid chondroma. |
