These disorders are due to abnormalities in the biosynthesis, interconversion and degradation of the purines—adenine and guanine—and of the pyrimidines—cytosine, thymine and uracil. All are heterocyclic bases which exist in tri-, di-, and mono-phosphorylated forms, and as either deoxyribosylated or ribosylated derivatives (deoxyribose and ribose are pentose carbohydrates). The phosphorylated deoxyribosylated and ribosylated derivatives are termed ‘nucleotides’, and the purely ribosylated derivatives, which lack the phosphate group, are ‘nucleosides’....
