these results suggest that there is a difference in the carbohydrate chains of glycoconjugates in the cones and rods : in the cones gal beta 1 -- -- 3galnac may be the terminal sugar as recognized by pna , whereas in the rods this sugar is contained in the carbohydrate chain but masked by terminal sialyl residues so that those glycoconjugates are inaccessible to pna without neuraminidase treatment .
