casein A group of phosphate-containing proteins isolated from milk. Casein is precipitated out of skimmed milk in acid conditions or by the action of rennin; it is readily digested by the enzymes of young mammals and represents a major source of phosphorus. Casein is very easily prepared and is useful as a protein supplement, particularly in the treatment of malnutrition. In alkaline solution, casein forms a colloid used as a glue, a binder for paint pigments and paper coatings, and to dress leather. Casein is also used to make plastics.
