Casein is the name for a family of related phosphor-proteins. These proteins are commonly found in mammalian milk, making up 80% in cow milk, and between 20% and 45% of the proteins in human milk. Casein has a wide variety of uses, from being a major component of cheese, to use as a food additive, to use as a binder for safety matches. As a food source, casein supplies amino acids, carbohydrates and two inorganic elements, calcium and phosphorus.
Casein protein contains fairly high number of praline residues, which do not interact. As a result, it has relatively little tertiary structure. It is relatively hydrophobic, making it poorly soluble in water. It is found in milk as a suspension of particles called “casein micelles” which show little resemblance with surfactant-type in a sense that the hydrophilic parts reside at surface in the spherical shape. The caseins are held together by calcium ions and the hydrophobic interactions. The most recent model proposes a double link among the caseins to gelling take place. The isoelectric point of casein is 4.6. Since milk’s pH is 6.6, casein has a negative charge in milk. The purified protein is insoluble. It is also insoluble in neutral solutions; it is readily dispersible in dilute alkalis and in salt solutions such as sodium oxalate and sodium acetate.
Casein protein- what it is and why it is good!!
Many people are not familiar with this. But it generally constitutes eighty percent in the whole part. It I more beneficial than other types of proteins because it gives diverse make up of amino acids and the duration time it remains in the body. It takes more time to digest and helps to slow down the breakdown of the proteins thereby increasing the muscles building up. Usually you should not take the proteins before going to bed because, it increases the fat content. But it is different in this Casein protein type. It must be taken before bed in order to delay your breakdown of muscles. The word casein actually derived from the Latin word meaning “cheese”. It contributes most part of the milk products in the type of salt. Because of its chemical makeup it cannot be denatured. It consists of different types of peptides depending upon what they are introduced to. Its structure is very basic as a result of its non reactant makeup. Although it is not completely hydrophobic as because these are freely suspend above the milk which means that they are part of molecule that would be reactant are not generally exposed to water in the first place.
