What is the difference between casein and caseinate?

Casein is a family of related proteins found in milk and cheese, known for its slow digestion and ability to form a gel or curd. Caseinate, on the other hand, refers to the salt form of casein that is created when casein is combined with an alkali, making it more soluble in water. This solubility enhances its use in various food products and nutritional supplements. Essentially, caseinate is a processed form of casein designed for easier incorporation into liquids.
