Application

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

Partial gastrointestinal digestion of casein is a rich source of bioactive peptides, such as β-casomorphin. However, bovine casein is not homogeneous; variants A1 and B do lead to production of β-casomorphin 7 production, while A2 does not.

Quality

Essentially vitamin free.

Preparation Note

Lactic acid precipitated New Zealand casein extracted with ethyl alcohol.

The regulation of UDP-Glc pyrophosphorylase (UGPase) isozyme, UGP5, was investigated in potato tuber. The cDNA for UGP5 was cloned into the bacterial expression vector pET21d and recombinant (RC) enzyme was expressed in E. coli (BL21 star cells). The RC-UGP5 isozyme...

Recent investigations have demonstrated an important role of gut microbiota (GM) in the pathogenesis of Alzheimer's disease (AD). GM modulates a host's health and disease by production of several substances, including lipopolysaccharides (LPS) and short-chain fatty acids (SCFAs), among others....
