title: Chemical characterization of the oligosaccharides in Bryde's whale (Balaenoptera edeni) and Sei whale (Balaenoptera borealis lesson) milk.
abstract: Samples of milk from a Bryde's whale and a Sei whale contained 2.7 g/100 mL and 1.7 g/100 mL of hexose, respectively. Both contained lactose as the dominant saccharide along with small amounts of Neu5Ac(alpha2-3)Gal(beta1-4)Glc (3'-N-acetylneuraminyllactose), Neu5Ac(alpha2-6)Gal(beta1-4)Glc (6'-N-acetylneuraminyllactose) and Neu5Ac(alpha2-6)Gal(beta1-4)GlcNAc(beta1-3)Gal(beta1-4)Glc (LST c). The dominance of lactose in the carbohydrate of these milks is similar to that of Minke whale milk and bottlenose dolphin colostrum, but the oligosaccharide patterns are different from those of these two species, illustrating the heterogeneity of milk oligosaccharides among the Cetacea.
