Biosynthesis of Nucleosides-5′-Triphosphates: Among animals, some amino acids cannot be synthesized and must there­fore be supplied through diet (essential amino acids). N1 of purine is derived from amino group of aspartate. Unlike the low solubility of uric acid formed by catabolism of purines, the end products of pyrimidine catabolism (carbon dioxide, ammonia, β-alanine, and γ-aminoisobutyrate) are highly water soluble.

The requirement of purine nucleotides is met by the salvage pathway. Additionally, free purines and pyrimidines can be degraded, the purines to the oxidized ring compound uric acid and the pyrimidines to smaller compounds (β‐amino acids, not the α‐amino acids found in proteins). The metabolic requirements for the nucleotides and their cognate bases can be met by both dietary intake or synthesis de novo from low molecular weight precursors.Indeed, the ability to salvage nucleotides from sources within the body alleviates any significant nutritional requirement for nucleotides, thus the purine and pyrimidine bases are not required in the diet. - Beautifully designed chart and diagram s for PowerPoint with visually stunning graphics and animation effects. - Metabolism of nucleic acids (4) Antagonists of deoxy- nucleotide biosynthesis (4) Antagonists of deoxy- nucleotide biosynthesis 3.

Purine and pyrimidine nucleotides are the building blocks of nucleic acids. Pyrimidine Synthesis In contrast to purines, pyrimidines are not synthesized as nucleotides. Pyrimidine biosynthesis Unlike in purine biosynthesis, the pyrimidine ring is synthesized before it is conjugated to PRPP. In contrast, purine nucleotides are created by attaching the simpler compounds directly onto the ribose molecule.
