Difference between A1 and A2 milk: Risk of A1 milk
, 2022 Milk is a primary source of nutrition for infants after the birth and also for human beings. Generally, milk is either from humans (women) or from cattle origin they contain various types of proteins, vitamins, minerals and so on. Components in milk show various beneficial actions in beings and some of the studies found that metabolites of it show ...

Detecting β-Casein Variation in Bovine Milk
Molecules, 2016 In bovine species, β-casein (β-CN) is characterized by genetic polymorphism. The two most common protein variants are β-CN A2 (the original one) and A1, differing from A2 for one amino acid substitution (Pro67 to His67).
