- Saponifiable lipids are lipids that undergo hydrolysis in basic solution. The following are saponifiable lipids EXCEPT ___.All lipids cannot interact with an aqueous solution. Is it right or wrong?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?
