Abstract/OtherAbstract:
|
This study was aimed at characterizing the glycoconjugates produced by the horse sublingual gland and, in particular, at discriminating between the sialoderivatives by means of differential oxidation and saponification combined with lectin histochemistry and enzymatic degradation. The results showed a predominance of sialoglycoconjugates with beta-galactose as acceptor sugar in the salivary mucins produced by the sublingual gland. Besides being the most represented terminal residue, sialic acid was also expressed in a great variety of derivatives distinguishable on the basis of acceptor sugars to the penultimate beta-galactose as well as linkage and acetylation degree of the pyranose ring and the polyhydroxyl side chain. A role in the protection of mucous membranes from physical, chemical and pathogenic agents can be hypothesized for the horse sublingual mucins. |
