Fmoc-3-苯乙烯基-L-丙氨酸

[S-(E)]-2-[芴甲氧羰基氨基]-5-苯基-4-戊烯酸是Fmoc保护的丙氨酸衍生物，可能对蛋白质组学研究和固相肽合成技术有用。丙氨酸是最简单的氨基酸之一-甲基为侧链。当掺入多肽链时，该小侧链赋予高度的灵活性（仅次于甘氨酸）。通常用诸如吡啶之类的碱除去Fmoc基团-这是酸性labile Boc基团的正交脱保护策略。

Fmoc-3-styryl-L-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.
