Amino Acid Analysis (AAA) is an integral part of analytical biochemistry. In a relatively short time, the variety of AAA methods has evolved dramatically with more methods shifting to the use of mass spectrometry (MS) as a detection method; another new aspect is miniaturization. However, most importantly, AAA in this day and age should be viewed in the context of Metabolomics as a part of Systems Biology. Amino Acid Analysis: Methods and Protocols,...
