Overview

Fmoc-alpha-Me-L-Leu-OH is an Fmoc protected leucine derivative that is potentially useful for proteomics studies and solid phase peptide synthesis techniques. Leucine is one of the more simple amino acids - an isobutyl group as the side chain. This smaller side chain confers a high degree of flexibility, and imparts a moderate hydrophobic effect 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.
