Amino Acids Labeled

Amino acids are organic compounds made of carbon, hydrogen, oxygen, nitrogen, and (in some cases) sulfur bonded in characteristic formations. Strings of amino acids make up proteins, of which there are countless varieties. Medical Isotopes supplies labeled amino acids such as L-Lysine-1-13C, Glycine-2,2-d2 and L-Aspartic Acid-2,3,3-d3.
