N-Glycolylneuraminic acid (Neu5Gc) is an abundant sialic acid, occurring in the glycoconjugates of most deuterostome animals. Neu5Gc differs from Neu5Ac by an additional oxygen atom in the N-acyl moiety.

It is generally accepted that normal human tissues do not contain Neu5Gc. Interestingly, chickens also appear to lack Neu5Gc.

In cancer tissues,Neu5Gc is differentially expressed on gangliosides or glycoproteins.
