The chemical reactions and pathways resulting in the formation of substances; typically the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones. The chemical reactions and pathways resulting in the formation of nucleobases, nucleosides and nucleotides. The chemical reactions and pathways resulting in the formation of adenine, 6-aminopurine, one of the five main bases found in nucleic acids and a component of numerous important derivatives of its corresponding ribonucleoside, adenosine. Any process that generates purine bases, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, from derivatives of them without de novo synthesis. The chemical reactions and pathways resulting in the formation of guanine, 2-amino-6-hydroxypurine, a purine that is one of the five main bases found in nucleic acids and a component of a number of phosphorylated guanosine derivatives whose metabolic or regulatory functions are important. The chemical reactions and pathways resulting in the formation of xanthine, 2,6-dihydroxypurine, a purine formed in the metabolic breakdown of guanine but not present in nucleic acids. The chemical reactions and pathways involving purine bases, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, which include adenine and guanine. The chemical reactions and pathways involving a nucleobase, a nitrogenous base that is a constituent of a nucleic acid, e.g. the purines: adenine, guanine, hypoxanthine, xanthine and the pyrimidines: cytosine, uracil, thymine. The chemical reactions and pathways resulting in the formation of hypoxanthine, 6-hydroxy purine, an intermediate in the degradation of adenylate. Its ribonucleoside is known as inosine and its ribonucleotide as inosinate. The chemical reactions and pathways resulting in the formation of a pigment, any general or particular coloring matter in living organisms, e.g. melanin. The chemical reactions and pathways resulting in the formation of a nucleobase, a nitrogenous base that is a constituent of a nucleic acid. The chemical reactions and pathways resulting in the formation of purine bases, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, which include adenine and guanine. The chemical reactions and pathways involving pigment, any general or particular coloring matter in living organisms, e.g. melanin.
