the presence of terminal alpha-d-galactosyl residues in the carbohydrate chains of glycoprotein antigens from the asexual blood stages of plasmodium falciparum is demonstrated by the alpha-d-galactosidase sensitivity of particular parasite antigens , the use of specific glycosidases to cleave sugars from parasite glycoproteins radiolabeled with [ 3h ] glucosamine , and the ability of bandeirea simplicifolia lectin , which has a specificity for terminal alpha-galactosyl residues , to bind to the parasite .
