Using a model based on the primary structure of αs1 -casein, the colloid stabilizing ability of fragmented protein and that of the intact chains are compared. We perform self consistent field (SCF) calculations to obtain the induced interaction potentials between the oil droplets, resulting from the overlap of adsorbed protein layers in each case. For the intact αs1 -casein, we confirm the know...

A method is described for isolating a crystalline protein of high tryptic activity from beef pancreas. The protein has constant proteolytic activity and optical activity under various conditions and no indication of further fractionation could be obtained. The loss in activity corresponds to the decrease in native protein when the protein is denatured by heat, digested by pepsin, or hydrolyzed ...

Serine proteases are the most versatile proteolytic enzymes with tremendous applications in various industrial processes. This study was designed to investigate biochemical properties, critical residues, and catalytic potential of alkaline serine protease using in-silico approaches. The primary sequence analyzed ProtParam, SignalP, Phyre2 tools signal peptide, secondary structure, respectively....

1. The experiments show that suspensions of finely divided particles of insoluble proteins incapable of swelling in acid (denatured egg albumin, casein trichloroacetate, sulfate, etc.) raise the viscosity of the suspension but little and that the influence of acid on the viscosity is negligible. 2. The same is true for solutions of certain genuine proteins such as genuine crystalline egg albumi...

The yoghurt consisted of low-fat milk, three bacterial strains starter, which included: L. bulgaricus ATCC 11842, plantarum 8014, and B. longum (1:1:1); purple sweet potato puree ( Ipomoea batatas, L.) carboxymethylcellulose sodium with the concentration 0.6%, 1.2%, 1.8%. Purple fortification in yogurt can prevent hypercholesterolemic conditions because it inhibits lipid sugar absorption intest...
