Possible Interaction: Caseins and Calcium Supplement

“Addition of calcium slightly decreased casein micelle size, while addition of citrate slightly increased micelle size.”

“ Casein micelle stability is negatively correlated with milk concentrations of ionic calcium , which may change according to the metabolic and nutritional status of dairy cows.”

“Thus increasing casein in the diet may help to stimulate bioavailability of calcium and increase bone density.”

“These differences cause significant changes in the ability of caseins to bind and stabilize calcium (Ca).”

“The absorption of phosphorus, calcium , and magnesium was higher for the casein diets than for the soy-containing diets.”

“The milk components lactose and casein enhance the apparent absorption of magnesium and possibly also of calcium , whereas phytate, which occurs in soya-bean products, has an inhibitory effect.”

“The endogenous phosphorylation reaction of the complex was little affected by addition of histone, cyclic nucleotides, Ca2+ -calmodulin, or Ca2+-phospholipid but was increased about two-fold by addition of casein.”

“At days 56-59, rats fed lactalbumin, 30% casein , soy and egg white exhibited significantly depressed urinary specific activity of calcium (P less than or equal to 0.001), and all rats fed test diets produced higher fecal endogenous calcium, suggesting an increased absorption.”

“In mammary tissue, the intracellular calcium concentration may acutely regulate synthesis and degradation of intracellular proteins, and the synthesis of casein.”

“… calcium (5 and … the casein permeation and thus increased the permeate purity, defined as a high whey protein-to-casein (g L−1/g L−1) ratio, … filtration performance, possibly due to the structural alteration of the deposited casein micelle layer, rendering the deposit more compact and more retentive.”
