However, in addition to disruption of the solvation layers of the proteins, these compounds also partially denature the proteins, exposing even more hydrophobic surface to the solvent. In practical terms. TCA is often the compound of choice amongst the …Denatured protein in the cell appears to act as a nucleation site for further aggregation of native, non-denatured protein [6], [17]. Thus, while protein insolubilization is indicative of protein denaturation, the amount of insoluble protein is not an accurate measure of the amount of protein actually denatured. 3.The presence of casein, salts and lactose in milk alter the reaction rates and orders for whey protein denaturation.
