This is my review. Please read the paper before reading my notes.

kappa-casein is the main glycoprotein of cow's milk.
Polysacharides on the kappa-casein are O-glycosidically linked.
3 sugars make up the kappa-casein, Gal, GalNac, NeuNac.
kappa-casein contains sialic acid!
kappa-casein is calcium insensitive.
They say that kappa-casein is the only part that contains sugars. I'm not so sure about this.
kappa-casein stabilizes the casein micelle.
kappa-casein can be split into two constituents. One is called para-kappa-casein and it is insoluable in water. The other contains the sugar groups and is soluable.
States that kappa-casein has N-acetyl and N-glycolyl neuraminic acid at terminal positions.
They also talk about lactotransferrin and suggest that the glycan groups play a role in intercellular adhesion.
