Acids tend to cause less damage than alkalis as many corneal proteins bind acid and act as a chemical buffer.

酸所造成的破坏要弱于碱性物质，因为许多角膜蛋白质可结合酸并起到化学缓冲的作用。

Peptide and protein can be obtained with high yield in aqueous buffer by coupling unprotected peptide segments without activation by enzymatic or chemical agents.

该方法使用非保护的多肽片段，无需酶或化学活化试剂，在缓冲溶液中能够高产率地获得多肽和蛋白质。
