We screened for foodstuffs affecting interferon-beta (IFN-beta) production of human foreskin diploid fibroblasts, in the presence of poly I.poly C, cycloheximide, and actinomycin D. alpha- and beta-caseins stimulated IFN-beta production dose-dependently, but kappa-casein inhibited it. Of the two chymosin fragments of kappa-casein, glycomacropeptide was an inhibitor but p-kappa-casein was not. b...

The pH of cheese affects the texture of curd directly by influencing the hydratation of the caseins; all else being equal, high pH cheeses are softer than more acid cheeses. pH also affects texture and flavour indirectly by affecting the activity of enzymes important to ripening and, in the case of the coagulant, the retention of enzyme in the curd during manufacture [1]. Since low pH is known ...

Milk is a fluid lacteal secretion obtained by the female of all mammals. Milk has an important function because it is a source of the essential nutrients for the proper development and maintenance of the human body. It must supply amino acids, vitamins, and minerals. It is very beneficial to balance human diet. Because milk has good quality protein such as caseins and serum proteins, it also ha...

1. Alkaline-earth-metal cations at low concentrations form soluble complexes with bovine caseins. The relative order of binding capacities is: Mg(2+)>Ca(2+)>Ba(2+)>Sr(2+). 2. The cations interact with both free ionized carboxyl groups of aspartic acid and glutamic acid and with monoester phosphate groups covalently bound to serine and threonine; at low concentrations of the cations interactions...
