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.
