He carried out a similar experiment to the one in the Indian Study. Once the casein protein is split along its long chain of amino acids (this happens via the bacterial breakdown within our gut during digestion when we drink a glass of milk or eat a hunk of cheese) a variation of short-chain amino acids known as casomorphins are produced. Naked Egg Experiment. The enzyme protease, present in the fresh pineapple on the left, broke down the structure of the gelatin liquefying it. Casein proteins, which form about 80% of the bovine milk proteins, form large colloidal particles with calcium phosphate to form casein micelles, which for many years have been an important subject of interest.
