Proteins are usually least soluble in water at their isoelectric points. Explain.
True or False:
Protein structure complexity depends on the number chains it is composed of and the amino acid composition.
Amino acids are ionic compounds, very soluble in water. Proteins, however, which are made up of amino acids are much less soluble, and must be folded up very precisely to maximize their solubility. Why are proteins so much less soluble than the amino acids of which they are made?
