The important role of casein peptide phosphate uptake of nutrition

Cereal in a person's diet contains a lot of phytic acid and phytic acid p into points, in the small intestine bottom PH7 ~ 8 environment combined with calcium and calcium phosphate precipitation. And CPP can dampen the formation of calcium phosphate precipitation, keep ca2 high concentrations, promoting passive absorption of calcium, vitamin D become as another way of calcium absorption accelerants.

Casein peptide phosphate (CPP) in milk casein as raw material, through biotechnology of bioactive peptides, can be used for various kinds of nutrition, health food, can effectively promote the body of calcium, iron, zinc and other divalent mineral nutrient absorption and utilization.

Casein peptide phosphate with pancreatic enzyme or trypsin hydrolysis of casein, after refining, purification, its core structure is: - Se r (P) - Se r (P) - Se r lu lu (P) - G - G - (lu Se r: serine, G: glutamic acid, P: phosphate group). The structure of the phosphoric acid serine residues (Se r (P) -) clusters, under the intestinal PH weak alkaline environment negatively charged, can prevent the further function of the digestive enzymes, CPP will not be further hydrolysis The stable existence in the intestine. Domestic studies have found that the molar ratio of nitrogen and phosphorus in the CPP is smaller, the shorter the CPP peptide chain, the greater the density of phosphate group, the higher the purity of the CPP, promote calcium absorption and utilization effect is stronger.
