Synopsis Amino acids are the molecular units that make up proteins. All proteins are various compositions of twenty specific naturally occurring amino acids. Amino acids are found in all food except oil. There are about eighty amino acids found in nature, but only twenty to twenty-nine are required for human growth. Amino acids play a pivotal role in living systems, and therefore synthetic amino acids have been of significant interest to researchers working towards the understanding and modification of physiological processes. Currently, the amino acids used in amino acid products are mainly manufactured by biocatalytic methods. The book presents detailed discussion of the preparation of amino acids by biocatalysis. It provides examples of recently developed biocatalytic methods for the production of amino acids and its derivatives. It offers upper level students and professionals an assential resource for pharmaceutical development, medicinal chemistry and biochemistry.
