Biochemistry of the Amino Acids, Second Edition, Volume II focuses on the trends in research on amino acids and biochemistry. Given considerations are incorporation of amino acids into proteins, amino acid sequences, and discovery of amino acids. The first part of the book deals with intermediary metabolism of amino acids. Particularly noted are alanine, aspartic, adenylosuccinic, hydroxyaspartic acids, and asparagine. The book also has discussions on glutamic acid, glutamine, glycine, serine, and sarcosine. The processes and syntheses involved in these acids are noted. Another part of the book focuses on the formation, degradation, reactions, and conversion of acids. The processes and experiments discussed are supported by numerical analysis, and the biosynthesis of acids in microorganisms is also considered. The book also notes some disorders of amino acid metabolism in humans. These disorders include cystinuria, glycinuria, ammonemia, prolinemia, maple syrup urine disease, and homocystinuria. Discussions focus on how these diseases develop and the symptoms associated with them. The book is a vital source of data for readers interested in the study of amino acids.
