Whey peptide is a small molecule protein peptide made from whey protein powder by enzymatic hydrolysis.Whey peptides retain all the nutritional value of whey protein.The whey protein mainly consists of β-lactoglobulin, α-lactoglobulin, bovine milk serum albumin (BSA), immunoglobulin and so on. Whey protein is a kind of amino acid balance of protein, their essential amino acid composition of fully meet the requirements of the even beyond the FAO/WHO is considered to be the amino acid content of the gold standard of scientific research confirmed that under the premise of whey protein on nutrition balanced, very easy digestion and absorption by human body, in the human breast milk contains 60% of whey protein.According to the evaluation standard that the value of high nutritional quality protein is 2.5, the potency ratio (PER) of whey protein is 3.0, which has obviously exceeded the PER value of high nutritional quality protein. Whey protein is considered as a protein with excellent nutritional quality. Because the branched chain amino acid concentration of whey protein is the highest in the natural food, the whey protein can provide energy for the body's endurance exercise process. In the process of exercise, the body's own protein synthesis is reduced and the protein is converted into free amino acids. Bones absorb branched amino acids from the blood and convert them into glucose to provide energy. Therefore, branched amino acids have their particularity among all amino acids and can provide energy for endurance exercise.
