Fmoc-3-（2'-喹啉基）-D-丙氨酸

Fmoc-3-（2′-喹啉基）-D-丙氨酸是Fmoc保护的丙氨酸衍生物，在蛋白质组学研究和固相多肽合成技术中具有潜在的应用价值。丙氨酸是一种最简单的氨基酸-甲基作为侧链。这种小的侧链赋予高度的灵活性（仅次于甘氨酸）时，纳入一个多肽链。Fmoc基团通常用吡啶之类的碱除去，这是一种与抗酸Boc基团正交的去保护策略。

Fmoc-3-(2′-quinolyl)-D-alanine is an Fmoc protected alanine derivative that is potentially useful for proteomics studies and solid phase peptide synthesis techniques. Alanine is one of the simplest amino acids – a methyl group as the side chain. This small side chain confers a high degree of flexibility (second only to glycine) when incorporated into a polypeptide chain. The Fmoc group is typically removed with a base such as pyridine – an orthogonal de-protection strategy to the acid labilie Boc group.
