Amino Acids

Amino Acids Reference Chart

Amino acids, such as glycine, arginine, and leucine, are important to both metabolic pathways and protein structure. They are used as building blocks for peptides defining structure and function. Different amino acids vary in both side chain polarity and pH. Sigma-Aldrich offers a full line of amino acids in varying purities and grades.
