Sialic acids e are 9-carbon α-keto acids and include N-acetylneuraminic acid (Neu5Ac), 2-keto-3-deoxy-d-glycero-d-galacto-nonulosonic acid (Kdn), 5,7-diamino-3,5,7,9-tetradeoxy-d-glycero-d-galacto-nonulosonic acid (legionaminic acid) and 5,7-diamino-3,5,7,9-tetradeoxy-l-glycero-l-manno-nonulosonic acid (pseudaminic acid), the last three being considerably rarer than Neu5Ac. 72 The 8-carbon α-keto acid, 2-keto-3-deoxy-d-manno-octulosonic acid (Kdo), is not a sialic acid but bears a striking

Sialic acid is primarily present on biopharmaceuticals linked as alpha2,3 or alpha2,6. SialEXO is a broad acting sialidase mix that will hydrolyze all sialic acid linkages including alpha2,3, alpha2,6, and alpha2,8. Sialic acids e are 9-carbon α-keto acids and include N-acetylneuraminic acid (Neu5Ac), 2-keto-3-deoxy-d-glycero-d-galacto-nonulosonic acid (Kdn), 5,7-diamino-3,5,7,9-tetradeoxy-d-glycero-d-galacto-nonulosonic acid (legionaminic acid) and 5,7-diamino-3,5,7,9-tetradeoxy-l-glycero-l-manno-nonulosonic acid (pseudaminic acid), the last three being considerably rarer than Neu5Ac.
