底物范围
- 适用范围
- A protected amino group and carboxyl group are coupled in a controlled sequence to form a peptide bond; the displayed equation is the net condensation relationship.
- 来源说明
- Simply heating unprotected amino acids does not provide a controlled preparative peptide synthesis. Laboratory synthesis requires activation or a coupling reagent plus protection strategy; biological protein synthesis is enzyme- and ribosome-controlled.

肽键可通过与盐酸水溶液长时间加热而水解；若需游离氨基酸，还须进行后处理。
