Structural Studies of Recombinant Human β-casein proteins
<p>β-Casein is the major component (~80%) of the human casein system. Interacting with calcium and phosphates through its phosphorylated N-terminus, β-casein participates in the formation of micelles which carry these otherwise insoluble nutrients indispensable for the growth and development of …

Studies on selected physicochemical properties and microstructure of β-casein-enriched ingredients for applications in formulated nutritional products
The milk protein β-casein (β-CN) possesses excellent functional properties and is the most abundant casein in human milk. Therefore, β-CN has the potential to be used as an ingredient in nutritional food applications, in particular in infant formulae (IF). However, the manufacture of β-CN products …

Studies on equine milk and comparative studies on equine and bovine milk systems
… nutrients and to possess an optimum whey protein:casein ratio, making it very suitable as a substitute for bovine milk in paediatric dietetics. There is some scientific basis for the special nutritional and health-giving properties of equine milk but this study provides a comprehensive analysis of …

Melt and Rheological Characteristics of Low Moisture Part Skim Mozzarella Cheese as Affected by the Starter Culture and Coagulating Enzymes
… showed a greater hydrolysis of α<sub>S</sub>- casein, whereas, cheeses made with sure curd showed a greater hydrolysis of β-casein. The extent of hydrolysis was found to be greater in MC cheeses at 6X level of coagulating enzyme. Maximum hydrolysis of α<sub>S</sub>- casein was ~70% in case of …

Primary proteolysis of caseins in cheddar cheese
… undertaken to investigate proteolysis of the caseins during the initial stages of maturation of Cheddar cheese. Isolated caseins were hydrolyzed by enzymes thought to be of importance during cheese ripening and the resulting peptides isolated and identified. Large peptides were also isolated …

Stabilisation of dehydrated nanoemulsions using sugar - protein matrices
… containing sunflower oil (10% w/w), β-casein (2.5–10% w/w) and lactose or trehalose (10–17.5%) were produced following optimisation of the continuous phase by maximising and minimising viscosity and glass transition temperature (Tg’) using mixture design software. Increasing levels of …

Extracellular amino acid effects on milk protein synthesis and free amino acid pools in cultured rat and bovine mammary cells
… and 7 fold significantly (P < .05) increased β-casein and to a lesser degree β-lactoglobulin synthesis by bovine mammary cells in culture. Individually increasing each of the 13 amino acids in MEM 3-fold showed cystine followed by threonine and then methionine significantly (P < .05) increased …

Predicting the Pose of β-Casomorphin-5 and 7 in the Opioid Receptors
… have shown that fragments of the milk protein, β-casein, known as β-casomorphins are agonists of these receptors which are selective for the μ receptor subtype. Using the crystal structures of these three receptors, computational molecular docking studies were done using the software GOLD to …

Novel Rac1/Stat3 and Stat5 Pathway in Differentiation and Neoplastic Transformation of Breast Epithelial Cells: Potential Prognostic Markers
… of HC11 breast epithelial cells, measured by β-casein expression. On the other hand, we also show that constitutively active Rac, a molecule downstream of cadherin in the Stat3 activation pathway, blocks the differentiation of breast epithelial cells. Stat5 is upregulated by hydrocortisone, …

The impact of genetic variation on functional, technological and digestive properties of β-lactoglobulin
… over 50 variants have been found among the four caseins (αs1-, αs2-, β-, and κ-casein) and the two main whey proteins, β-lactoglobulin (β-lg) and α-lactalbumin. In the early 1990’s, it was speculated that certain genetic variants of β-casein could be associated with negative health effects, …
