Boc-Ala-OH; Boc-L-alanine 15761-38-3 is the boc protection form of L-Alanine, a non-essential amino acid that can be found naturally in the human body. The methyl group that forms the alanine sidechain is small and non-reactive, thus alanine is seldom directly active in peptide bonding to receptors. By replacing an amino acid in a peptide sequence with alanine and observing the activity of the resulting peptide, the importance of the replaced residue to the activity of the peptide can be determined. A library of peptides in which alanine has been systematically substituted at each postion is called an alanine scan library. Boc-Ala-OH can be used to prepare scan libraries for SAR studies to identify the residues within a peptide that are critical for the peptide's activity.
