Occurrence of Hematoside with Two Moles of N-Acetyl-neuraminic Acid in a Certain Breed of Persian Cat

Abstract

The glycolipids of erythrocytes from individual cats were examined. The main glycolipid
of cat erythrocytes was generally NeuGc-NeuGc-Gal-Glc-ceramide (NeuGc-GD₃), but among 41 cats of 5 breeds and 2 mongrels examined, 2 Persian cats were found to have NeuAc-NeuAc-Gal-Glc-ceramide (NeuAc-GD₃). This is the first report of the occurrence of NeuAc-GD₃ in cat erythrocyte membranes.
