protein aggregation and precipitation is associated with many debilitating diseases including alzheimer's, parkinson's, and light-chain amyloidosis. β-casein, a member of the casein family, has been demonstrated to exhibit chaperone-like activity to protect protein form aggregation. hofmeister salts (lyotropice series) are a class of ions which have an effect on the solubility and also the stab...

The present investigation was carried out to evaluate anticancer activity of cow, goat, sheep, mare, donkey and camel milks and their casein and whey proteins against MCF7 cell line. The structure-based properties of the casein proteins were also investigated, using bioinformatics tools to find explanation for their antitumor activities. The effect of different milks and their casein and whey p...

We have shown that feeding cod protein, which is rich in anti-inflammatory arginine, glycine, and taurine, may beneficially modulate the inflammatory response during recovery following skeletal muscle injury; however it is unknown if these amino acids are responsible for this effect. This study was designed to assess whether supplementing casein with an amino acid mixture composed of arginine, ...

Various compounds have been used for microencapsulating of fish oilso far, but in thiswork for the first time, inulin and casein which are both known for their functional properties, were used as the coating materialof fish oil.This study aimed to investigate the properties of nano-emulsions (droplet size measurements and pH) based on changes in the concentration and type of wall and their effe...

Casein is the collective name for a family of milk proteins. In bovine milk, casein comprises four peptides: αS1, αS2, β, and κ, differing in their amino acid, phosphorus and carbohydrate content but similar in their amphiphilic character. Hydrophilic and hydrophobic regions of casein show block distribution in the protein chain. Casein peptides carry negative charge on their surface as a resul...

Foods that have a low glycaemic index or foods that contain slowly digestible starch are beneficial in controlling fluctuations in blood glucose and insulin levels. The study hypothesis is that gelatinisation of starch in structured casein networks provides a method for decreasing the digestion rate of the starch and, hence, minimising postprandial glucose fluctuations. This study examined the ...

A phospho-oligosaccharide, whose production is stimulated by insulin, modulated the activity of partially purified casein kinase II. Whereas at 2 microM the phospho-oligosaccharide stimulated casein kinase II 1.3-fold, higher concentrations of this molecule were inhibitory. 50% inhibition of the enzyme was obtained at 15 microM phospho-oligosaccharide. This biphasic effect of the phospho-oligos...

BACKGROUND A major protein component of cow's milk is β-casein. The most frequent variants in dairy herds are A1 and A2. Recent studies showed that milk containing A1 β-casein promoted intestinal inflammation and exacerbated gastrointestinal symptoms. However, the acute gastrointestinal effects of A1 β-casein have not been investigated. This study compared the gastrointestinal effects of milk c...

Casein kinase 2 activity could be resolved into three peaks by chromatography on DEAE-Sepharose. The peak eluted at high salt concentrations (casein kinase 2b) showed molecular and kinetic properties typical of the heterotetramer composed of a(or a'-) and fl-subunits. In contrast, the peak that was eluted at low salt concentrations (casein kinase 2a) contained no fl-subunit but a phosphorylatab...

The major physiological function of milk is the transport of amino acids, carbohydrates, lipids and minerals to mammalian offspring. Caseins, the major milk proteins, are secreted in the form of a micelle consisting of protein and calcium-phosphate.We have analysed the role of the milk protein α-casein by inactivating the corresponding gene in mice. Absence of α-casein protein significantly cur...
