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.

The benefits of soy peptide on the human body

Soy peptides is the macro-molecule of soybean protein, the use of biological enzyme technology into from 2 to 10 small molecular fragments of amino acids. Soybean peptide are rich in 22 kinds of amino acids, including 9 kinds of essential amino acids the human body can't synthesis. [1] soy peptide of small molecule protein, very easy to be absorbed by human body, suitable for protein digestion and absorption to people with weak consumption, such as the elderly, convalescence after surgery patients, tumor and radiation and chemotherapy patients, gastrointestinal function not beautiful, etc. In addition, the soybean peptide also has to improve immunity, enhance physical strength, relieve fatigue, down three higher efficacy.
Soy peptide of small molecule protein, it is very easy to be absorbed by human body, the absorption rate is 20 times average protein, amino acids, 3 times for protein digestion and absorption of poor people, such as the elderly, convalescence after surgery patients, tumor and radiation and chemotherapy patients, gastrointestinal function not beautiful, etc.
Soy peptides contain arginine, glutamic acid. Arginine can increase the important immune organs - the volume of the thymus gland immunity and health; A large number of virus invades the body, glutamate produces immune cells, to fend off viruses.
Soy peptide can make sympathetic activation, induce the activation of brown adipose tissue function, thus promotes energy metabolism, can effectively reduce body fat, while maintaining skeletal muscle weight remains the same.
