Given below are two statements: Statement I : Amino acids have a property of ionizable nature of $-\mathrm{NH}_2$ and $-\mathrm{COOH}$ groups, hence have different structures at different $\mathrm{pH}$. Statement II : Amino acids can exist as Zwitterionic form at acidic and basic $\mathrm{pH}$. In the light of the above statements, choose the most appropriate answer from the options given below:

(d) Lipids are generally insoluble in water but soluble in some organic solvents.

(e) When a fatty acid is esterified with gIycerol, monoglycerides are formed.
