Deriviatization, Hydrolysis, and HPLC Analysis of Amino …
Amino acid analysis enables precise determination of protein quantities and provides detailed information regarding the relative amino acid composition and free amino acids. The relative amino acid composition gives a characteristic profile for proteins, which is often sufficient for protein identifiion, and is often used as a deciding factor for choosing proteases for protein fragmentation.

Rhodium GHB Synthesis FAQ - Erowid
Ester hydrolysis can be done in two ways: An acid alyzed reaction or a base alyzed reaction. The base alyzed reaction is our choice here, because the reaction is not reversible like the acid alyzed one and therefore we will get higher yields, and we will get the sodium salt of GHB, as the free acid is not stable, and will immediately cyclize into gamma-butyrolactone again.
