| General description【一般描述】 | Casein is produced from skim milk. It is roughly made of 80% bovine milk protein and has only 10 to 20% essential amino acids per gram of protein. |
| Application【应用】 | Casein from bovine milk is a phosphoprotein. There are four main types of Casein which make up approximately 80% of the total protein in bovine milk: α-s1 Casein, α-s2 Casein, β-Casein, and κ-Casein. Casein is proposed to be the main protective constituent in milk. |
| Biochem/physiol Actions【生化/生理作用】 | Casein is considered as a slow digesting protein as it digests at a slower rate than other proteins. It also has an anti-catabolic effect. 部分消化的酪蛋白是生物活性肽的丰富来源，如β-酪啡肽。然而，牛酪蛋白是不同质的；A1和B变异的确会导致产生β-酪啡肽7，但A2却不会。 |
