The coefficient of variation amounts to 4–10%..The use of the method is suggested to laboratories having an amino acid analyzer and wish to determine D- and L-amino acids in synthetic amino acids complements, peptides or natural materials.

Both biocatalysts illustrate the exceptional feature that they accept a broad structural range of substrates..HPLC and NMR analytical techniques have been developed in order to establish the enantiomeric purity of the α-H- and α-alkyl α-amino acids and amides.

From this product, a methoxyphenyl kainoid (3-carboxy-methylproline with methoxyphenyl group at C4) with the same configuration in pyrrolidine ring as kainic acid was derived. The methoxyphenyl kainoid showed potent activity comparable to that of acromelic acid B or domoic acid.

Added to this role, however, is their ability to serve as building blocks for the production of many classes of secondary meta

The importance of the labelling position in the molecule and some special problems encountered when working with short-lived radionuclides of high specific radioactivity are discussed.
