Abstract
The composition of the human erythrocyte membrane (RBC) glycoprotein- and glycolipid-bound sialic acids of A, B, AB and O type donors was studied using a new method (Zanetta et al., Glycobiology 11 (2001) 663–676). In addition to Neu5Ac as the major compound, Kdn, Neu5,9Ac 2, Neu5,7Ac 2, Neu (de- N-acetylated-Neu5Ac), Neu5Ac8Me, Neu5Ac9Lt, Neu4,5Ac 2, Neu5,8Ac 29Lt and Neu5Ac8S were characterised. Among these different compounds, Neu5Ac8Me, Neu5Ac9Lt, Neu4,5Ac 2, Neu5,8Ac 29Lt and Neu5Ac8S have never been described and quantitatively determined before in human tissues or cells. Neu5Gc and its O-alkylated or O-acylated derivatives were not detected.
