Differential Release of β-Casomorphins from A1 and A2 Milk During Standardized Gastrointestinal Digestion Quantified by CE–MS [PDF]
Foodsβ-Casein A1 and A2 (β-CN-A1 and β-CN-A2) are the two predominant β-CN proteoforms in bovine milk. β-CN-A1 has been associated with a greater propensity to release opioid peptides, such as β-casomorphin-7 (β-CM-7) and β-casomorphin-5 (β-CM-5), during ...

Effects of β-casein A1/A2 milk and β- and κ-casein genotypes on the performance, body composition, and fecal score of dairy calves [PDF]
Scientific ReportsThe perceived health benefits of β-casein (β-CN) A2 milk for humans have driven increased selection for homozygous β-CN A2 dairy cattle. However, little is known about the effects of feeding milk with different β-CN variants to calves, or about the ...

Frequency of A1 and A2 alleles of the β-casein gene in cattle in the Cajamarca region of Peru [PDF]
Open Veterinary JournalBackground: Cow's milk β-casein has multiple genetic variants, the two most common of which are A1 and A2, which are encoded by the CSN2 gene. Evidence suggests that the A1 variant may negatively affect human health.

Detection and Validation of A2 Milk Suitable for Consumers Having Milk Intolerance by ELISA Method
Journal of Advanced Research in Natural and Applied Sciences, 2023 Casein proteins, which make up 80% of the total proteins in cow's milk, consist of mainly A1 and A2 genetic types which differ by a mutation that causes conversion from proline to histidine.
