Metabolic Pathways, Volume II focuses on the metabolism, biosynthesis, and catabolism of amino acids. The selection first offers information on nitrogen and carbon metabolism of amino acids. Discussions focus on amino acids linked with citric acid cycle, sulfur amino acids, proline and hydroxyproline, histidine, hydroxyamino acids, urea biosynthesis and related systems, and deamidation. The text then ponders on the biosynthesis of amino acids and related compounds and metabolism of sulfur-containing compounds. Topics include metabolism of methionine, biotin, biological importance of sulfur in animals, interconversions of glutamic acid, ornithine, and prolines, and biosynthesis of the branched-chain amino acids. The publication takes a look at the synthesis of proteins, purines and pyrimidines, and nucleotides and nucleosides, including the components of nucleotides, purine degradation, and incorporation of preformed purine compounds into nucleic acids. The selection is a valuable reference for researchers interested in the metabolism, catabolism, and biosynthesis of amino acids.
