Which milk protein is most difficult to digest?

Explanation:
Milk proteins fall into two main groups: casein and whey. Whey proteins are water-soluble and are rapidly digested by gastric and pancreatic enzymes, so they’re absorbed quickly. Casein behaves differently: in the acidic environment of the stomach, with calcium present, casein coagulates into a soft curd. This curd formation slows access of proteases, slows gastric emptying, and releases amino acids more gradually. Because of this slower digestion and absorption, casein is the more difficult milk protein to digest.
