CASEIN BRP

α-Casein, from bovine milk

Casein is a milk protein with multiple roles involved in novel drug delivery systems.

Natural protein source, typically isolated from bovine milk.Casein is widely used as a food additive. It is useful in tooth remineralization products to stabilize amorphous calcium phosphate. It is also used as a type of organic adhesive and a binder for safety matches. It supplies amino acids and carbohydrates and two inorganic elements such as calcium and phosphorus. Further, it is also used in the production of transformer board due to its oil permeability. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Casein is a type of protein found in milk, which is the main component of cheese. Casein is used as an ingredient in many foods, such as cheese and other dairy products. It is also used in some medicines to treat infant colic, although it has been shown that casein does not have any effect on the symptoms of colic. Casein contains a large number of sulfur-containing amino acids, which make up about one third of its total content. These amino acids form disulfide bonds between different caseins in the micelles. The pH optimum for the solubility of casein is around 6.6, while the pI (isoelectric point) is 4.6-5.1. Casein has been shown to be effective as a binder for monoclonal antibodies and carboxy terminal enzymes in vivo treatment studies, and also shows adsorption properties due to its calcium binding properties.

Casein is a phosphoprotein, which is derived from milk. It originates primarily from cow's milk, where it constitutes about 80% of the total protein content. The mode of action for casein involves its ability to form a gel or clot in the stomach, which makes it highly efficient in nutrient delivery, especially the slow release of amino acids. This process is facilitated by its unique structural features, such as the presence of multiple phosphoryl groups that can bind calcium ions. Casein is widely utilized in various applications due to its multifunctional properties. In the food industry, it serves as a vital ingredient in cheese production, offering texture and nutritional value. Beyond culinary uses, casein plays a critical role in non-food industries; it's used in adhesives, paints, and even some cosmetics, owing to its excellent binding properties. Additionally, casein's emulsifying capacities make it an important component in the production of certain processed foods. Its versatility and effectiveness highlight its significance in both scientific inquiry and practical applications.
