Nucleic acid metabolism

Nucleic acid metabolism refers to the set of chemical reactions involved in the synthesis and degradation of nucleic acids (DNA and RNA). Nucleic acids are polymers (biopolymers) composed of monomers called nucleotides.

Nucleotide synthesis is an anabolic process that typically involves the chemical reaction of a phosphate group, a pentose sugar, and a nitrogenous base. In contrast, the degradation of nucleic acids is a catabolic process in which nucleotides or nucleobases are broken down, and their components can be salvaged to form new nucleotides.

Both synthesis and degradation reactions require multiple enzymes to facilitate these processes. Defects or deficiencies in these enzymes can lead to a variety of metabolic disorders.
