Beta-casein
Human beta-casein is the major protein found in human milk. The protein binds to calcium at its phosphorylated regions, which in turn are highly conserved. The calcium then binds the caseins together and forms micelles, which better enable it to be ingested by infants. It also has opioid type effects on newborn sleeping patterns. The protein, as a whole, is disordered and is characterized as a random coil protein. This structure can be modified to some extent with an increase of temperature.
