Sigma-Aldrich is proud to offer you a comprehensive offering of amino acid derivatives that are useful in a variety of peptide and peptidomimetic syntheses. Our collection includes a diverse selection of protected amino acid derivatives including Fmoc, Boc and Cbz protecting groups. Amino acids are the building blocks or basic structural units of peptides and proteins and have a wide range of biological functions both as single units as well as parts of these larger polymeric forms. There are 20 standard amino acid derivatives or proteinogenic derivatives that make up all of the peptides and proteins in humans and eukaryotes. In addition to biological use, many amino acid derivatives are useful as asymmetric building blocks in chemical synthesis as they have high enantiomeric purity.
Whatever your application may be, we are confident that our range of derivatives of amino acids will satisfy your synthetic needs.
