The chemical reactions and pathways resulting in the breakdown of small molecules, any monomeric molecule of small relative molecular mass. The chemical reactions and pathways resulting in the breakdown of a nucleoside triphosphate, a glycosamine consisting of a base linked to a deoxyribose or ribose sugar esterified with triphosphate on its glycose moiety. The cellular chemical reactions and pathways involving nucleobases, nucleosides and nucleotides. The chemical reactions and pathways resulting in the breakdown of a nucleoside diphosphate, a glycosamine consisting of a base linked to a deoxyribose or ribose sugar esterified with diphosphate on its glycose moiety. The chemical reactions and pathways resulting in the breakdown of a pyridine nucleotide, a nucleotide characterized by a pyridine derivative as a nitrogen base. The chemical reactions and pathways resulting in the breakdown of a pyrimidine nucleotide, a compound consisting of nucleoside (a pyrimidine base linked to a deoxyribose or ribose sugar) esterified with a phosphate moiety at either the 3' or 5'-hydroxyl group of its glycose moiety. The chemical reactions and pathways resulting in the breakdown of nucleotides, any nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the glycose moiety; may be mono-, di- or triphosphate; this definition includes cyclic-nucleotides (nucleoside cyclic phosphates). The chemical reactions and pathways involving any phosphorylated nucleoside. The chemical reactions and pathways resulting in the breakdown of a purine nucleotide, a compound consisting of nucleoside (a purine base linked to a deoxyribose or ribose sugar) esterified with a phosphate moiety at either the 3' or 5'-hydroxyl group of its glycose moiety. The chemical reactions and pathways resulting in the breakdown of a deoxyribonucleotide, a compound consisting of deoxyribonucleoside (a base linked to a deoxyribose sugar) esterified with a phosphate moiety at either the 3' or 5'-hydroxyl group of its glycose moiety. The chemical reactions and pathways resulting in the breakdown of a nucleoside bisphosphate, a glycosamine consisting of a base linked to a deoxyribose or ribose sugar esterified with one phosphate group attached to each of two different hydroxyl groups on its glycose moiety. The chemical reactions and pathways resulting in the breakdown of nucleobases, nucleosides and nucleotides. The chemical reactions and pathways resulting in the breakdown of nucleobases, nucleosides, nucleotides and nucleic acids. The chemical reactions and pathways resulting in the breakdown of a ribonucleotide, a compound consisting of ribonucleoside (a base linked to a ribose sugar) esterified with a phosphate moiety at either the 3' or 5'-hydroxyl group of its glycose moiety. The chemical reactions and pathways resulting in the breakdown of a nucleoside monophosphate, a glycosamine consisting of a base linked to a deoxyribose or ribose sugar esterified with phosphate on its glycose moiety. Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the breakdown of nucleotides. Any process that stops, prevents or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the breakdown of nucleotides. Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the breakdown of nucleotides. The chemical reactions and pathways involving a nucleotide, a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the glycose moiety; may be mono-, di- or triphosphate; this definition includes cyclic nucleotides (nucleoside cyclic phosphates).
