底物范围
- 适用范围
- Prolonged heating with concentrated aqueous hydrochloric acid hydrolyses peptide bonds to give amino-acid hydrochloride salts before neutralisation.
- 来源说明
- The displayed product equation is a net relationship. Under the stated acidic conditions the immediate products contain protonated amino groups; alkaline hydrolysis is a distinct procedure and gives carboxylate salts until acid work-up.
