polymorpha" produces glycoproteins with two types of sugar chains, N- and O-linked glycans are attached to protein.Studies on the structure of N-linked chains have revealed a certain average length (Man8-12GlcNAc2) with terminal alpha-1,2-linked mannose residues, and not with allergenic terminal alpha-1,3-linked mannose residues as found in other yeasts, especially in the baker’s yeast "Saccharomyces cerevisiae".
