保护氨基酸是指在合成多肽或蛋白质时，对氨基酸的功能基团进行保护，防止在合成过程中发生不必要的副反应。这种保护通常通过化学方法实现，使得氨基酸的特定基团（如氨基、羧基、侧链基团）在特定步骤中不会发生反应。等到需要该基团反应时，再通过去保护步骤去除保护基团。
保护氨基酸在固相多肽合成（Solid-phase peptide synthesis，SPPS）中尤为重要，因为它们可以确保合成过程的高效性和准确性。例如，在合成过程中，常见的保护基团包括但不限于：
氨基保护基团：Boc (tert-Butoxycarbonyl)；Fmoc (9-Fluorenylmethyloxycarbonyl)
羧基保护基团：甲基酯（Methyl ester, -COOCH3）；苄基酯（Benzyl ester, -COOCH2Ph）
羟基保护基团：甲氧基甲基（MOM, Methoxymethyl ether）；甲硅烷基（TBDMS, tert-Butyldimethylsilyl ether）
巯基保护基团：三苯甲基（Trityl, Trt）；乙酰基（Acetyl, Ac）
