Fmoc-β-氯-L-丙氨酸是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-beta-chloro-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.
