Vedclass · Answer

(D) Proteins are complex macromolecules that exhibit varying solubility depending on their structure and the solvent environment.$1$. Many proteins are soluble in water,especially globular proteins,due to the presence of hydrophilic amino acid residues on their surface.$2$. Proteins are often highly soluble in dilute acidic or basic solutions because the change in $pH$ alters the ionization state of the amino acid side chains,increasing electrostatic repulsion between protein molecules.$3$. Some proteins also show solubility in dilute alcohol solutions.Therefore,proteins can be soluble in all the mentioned solvents depending on the specific type of protein and conditions.
