Abstract: Purine nucleotide degradation refers to a regulated series of reactions by which human purine ribonucleotides and deoxyribonucleotides are degraded to uric acid in humans. Inborn errors of pyrimidine metabolism include disorders of pyrimidine synthesis and of pyrimidine nucleotide degradation. Obsessive-Compulsive Disorder (OCD) and Related Disorders in Children and Adolescents. Nucleic acid metabolism is the process by which nucleic acids (DNA and RNA) are synthesized and degraded.Nucleic acids are polymers of nucleotides.Nucleotide synthesis is an anabolic mechanism generally involving the chemical reaction of phosphate, pentose sugar, and a nitrogenous base.Destruction of nucleic acid is a catabolic reaction. The main metabolic pathways in red cell are the anaerobic glycolysis, the hexose monophosphate shunt, the glutathione cycle, and nucleotide metabolism. Because mitochondria contain their own machinery for nucleoside and nucleotide metabolism and have physically separate nucleotide pools, it is not surprising that disorders of these pathways cause human diseases.
