Because of the low pH qualities, casein is often characterized as a slow-digesting protein, which tends to enhance satiety and prolong the post-prandial period of amino acid absorption and appearance in the blood circulation.60,61 The digestive properties of proteins have been extensively studied for use in protein powders to support protein synthesis in skeletal muscle, and the optimal protein choices depend on the application.38,62,63 For example, whey proteins are routinely used as protein supplements, because they have a high leucine content (12% w/w) and are rapidly digested, producing the rapid rise in plasma and intracellular leucine concentrations essential for the mTOR trigger for muscle protein synthesis.38 Whey is ideal for providing a maximum response with the least amount of protein and calories, plus it is water-soluble and has a clean flavor profile. Many of these proteins have unique bioactivities. Full content visible, double tap to read brief content. Contact your health-care provider immediately if you suspect that you have a medical problem. The biological components of whey, including lactoferrin, beta-lactoglobulin, alpha-lactalbumin, glycomacropeptide, and immunoglobulins . Please try again. Over the 3-month period, glutathione levels increased in all 3 cases. In native milk, caseins exist in a micellular structure to maintain water solubility; however, in acidic environments (pH<4.6), casein proteins curdle, forming a curd, providing the characteristics that led to its use in cheese-making.59, Likewise, the low solubility in acidic environments causes casein to curdle in the low pH of the stomach, slowing gastric emptying and prolonging digestion and absorption. These studies, which included patients with prediabetes,111 type 2 diabetes,112,113 or gestational diabetes,114 or healthy adults115119 randomized to the protein hydrolysate or native form of whey or casein, found limited and inconsistent evidence of improved glucose control in the hydrolysate groups (eg, plasma levels of glucose-dependent insulinotropic polypeptide,116 glucose,118,120 and/or insulin113,119121). Aging, weight management, type 2 diabetes, bed rest, acute injury, and chemotherapy are all conditions in which body composition, muscle mass, and metabolic health are determinates of long-term outcomes.27,3032 The key finding that linked whey protein to skeletal muscle health was the discovery of the role of mechanistic target of rapamycin (mTOR) in regulating post-meal anabolic responses in skeletal muscle.

An official website of the United States government. N.A. Whey protein is a good source of cysteine, which helps maintain adequate glutathione production. Although much knowledge has been attained through bioinformatics, research on the bioavailability and effectiveness of bioactive peptides in humans is limited. This process occurs with continuous cycling between the synthesis and breakdown of proteins, and while skeletal muscle accounts for approximately 50% of total body protein, it receives only about 25% of the newly formed proteins.35 The body prioritizes de novo protein synthesis to essential organs, including the liver, heart, and GI tract. For example, little is known about the bioavailability of IPP and VPP in humans,98 and their physiological targets and biological mechanisms of action in humans have not been characterized. The effect of dairy consumption on the prevention of cardiovascular diseases: a meta-analysis of prospective studies, Dairy consumption and cardiometabolic diseases: systematic review and updated meta-analyses of prospective cohort studies. Casein has a more moderate leucine content (9%), is slow digesting, and has low solubility, resulting in a lower and more prolonged leucine absorption profile.
