Amino Acids and Derivatives
Amino acid derivatives include amino acid esters, amino acid amides and other protected amino acids suitable for the solution phase synthesis of peptides. These products include a wide selection of amino acid methyl esters, amino acid tert-butyl esters, benzyl esters and ethyl esters. Amino acid para-nitroanilides, used to prepare substrates for enzyme studies, are some of the other derivatives availableAll amino acids contain an amine group, a carboxylic acid group, and a side-chain that varies for each amino acid. Amino acids can be classified into groups based on the chemical properties of their side chains: aliphatic, aromatic, basic, and acidic, and neutral. L-stereochemistry overwhelmingly predominates amino acids found in nature. Twenty amino acids are directly encoded by the genetic code of eukaryotes.
