Amino acids are organic compounds that contain amine -NH 2 and carboxyl -COOH functional groups , along with a side chain R group specific to each amino acid. About naturally occurring amino acids are known though only 20 appear in the genetic code and can be classified in many ways. In the form of proteins , amino acid residues form the second-largest component water is the largest of human muscles and other tissues. In biochemistry , amino acids having both the amine and the carboxylic acid groups attached to the first alpha- carbon atom have particular importance. They include the 22 proteinogenic "protein-building" amino acids, [7] [8] [9] which combine into peptide chains "polypeptides" to form the building-blocks of a vast array of proteins. Twenty of the proteinogenic amino acids are encoded directly by triplet codons in the genetic code and are known as "standard" amino acids.

This book is not a systematic treatise on the chemistry of amino acids, peptides and proteins or even on the physical chemistry of these important substances. It deals with them from the limited point of view of the number and distribution of the electrical charges they bear and the "implications of their charged structure for their physical properties and their physicochemical interaction with other molecules. By applying these fundamental concepts to theoretical and experimental studies of amino acids, peptides and proteins, the authors and their associates have paved the way to new and.
