High impact information on Gal(beta1-3)-gal(beta1-4)glc

Unique to elephant milk are the high levels of 3'-galactosyllactose (up to 4 g/l) and lacto-N-neo-tetraose which are present in human milk only in trace amounts [1].
B-pentasaccharide was a dominant saccharide in early lactation milk, while alpha 3'-galactosyllactose was dominant in milk, later [2].
The chemical structure of the three trisaccharides were determined by methylation and 13C-NMR analyses to be as follows: Gal alpha 1-3Gal beta 1-4Glc, Gal beta 1-3Gal beta 1-4Glc (3'-galactosyllactose) and Gal beta 1-6Gal beta 1-4Glc (6'-galactosyllactose) [3].

Anatomical context of Gal(beta1-3)-gal(beta1-4)glc

Separation of human milk oligosaccharides by recycling chromatography. First isolation of lacto-N-neo-difucohexaose II and 3'-Galactosyllactose from this source [4].
