First group is called the main proteins which include Casein and two types of Whey proteins called a Lactalbumin and ss Lactoglobulin.
However, the terms "casein", "caseinate" and "lactalbumin" were identified by less than 25% of the respondents, emphasizing the lack of knowledge of technical terms by the population.
Thereafter, total serum IgE and specific IgE against wheat, barley, oats, rye, gluten, and cow's milk proteins ([beta]-lactoglobulin, lactalbumin, and casein) were measured by f luorometric sandwich immunoassay using Immuno-CAP system (Phadia, Uppsala, Sweden) with a detection range of 2-5000 kU/L and 0.1-100 k[U.sub.A]/L, respectively, where A represents the allergen-specific antibodies.
Skin prick tests (SPTs) were performed on each patient for common inhalants and food allergens (Lofarma, Milan, Italy): Dermatophagoides pteronyssinus (Der P), Dermatophagoides farinae (Der F), dog/cat dander, Olea europaea, Lolium perenne, Alternaria alternata, Parietaria officinalis, lactalbumin, [beta]-lactoglobulin, casein, egg white and yolk, soy, and cod fish.
Competition of Complex Formation between DnaK and Reduced Carboxymethylated Lactalbumin (RCMLA) by Insulin Peptides.
Whey proteins, as a non-casein fraction of milk proteins and as biologically most valuable proteins, comprise lactalbumin, lactoglobulin, and protease peptone [15].
Component Supplement Percent content of total supplement Whey proteins 8.8-9.2 g 88-92% ([beta]- lactoglobulin, immunoglobulin, serum albumin, [alpha]- lactalbumin, and lactoferrin) Fat ~0.05g <0.5% Lactose ~0.15g <1.5% Minerals (Ca, Na) ~0.30g <3.0% Moisture 0.5 g ~5% Table 2: Cystine [(Cys)2] and glutamylcysteine [Glu-(Cys)2] content of Immunocal whey proteins.
Detroit 562 cells were cultured in minimum essential medium alpha supplemented with 2mM glutamine, 1% nonessential amino acids, 1mM sodium pyruvate, 0.1% lactalbumin hydrolysate, 10% (vol/vol) fetal bovine serum (FBS), 100 [micro]gm [L.sup.-1] streptomycin, and 100 units [mL.sup.-1] penicillin, and NCI-H292 cells were cultured in RPMI1640 medium supplemented with 2mM glutamine, 10% (vol/vol) FBS, 100 [micro]g[mL.sup.-1] streptomycin, and 100 units [mL.sup.-1] penicillin, in a water-saturated atmosphere of 95% air and 5% C[O.sub.2] at 37[degrees] C.
Besides the decreased volume of milk produced as a result of mastitis [14], the physical and chemical composition of milk changes, such as, the casein, major protein, decreases as a consequence of infection and the whey proteins (lactalbumin and lactoglobulin) are increased by augmented vascular permeability, reduces the stability of the milk to heat by coagulation or flocculation during pasteurization and ultrapasteurization processes, also there is a decreased calcium in milk; factors affecting milk yield in the production of cheese [12], potassium predominant mineral in milk, declines and the concentrations of sodium and chloride ions rise and increases the electrical conductivity.
A Milk and other dairy products contain lactalbumin, a protein rich in tryptophan, which may trigger the hormones melatonin and serotonin in the brain.
