Study Notes
- Genetic information for protein synthesis is transcribed from DNA to mRNA.
- Translation turns the three-base code in mRNA into a 20-unit code for amino acid sequence.
- Purine nucleotides are synthesized in most tissues, with the major site being the liver.
- The de novo synthesis pathway for purine nucleotides has ten steps and occurs in the liver.
- The salvage pathway recycles purines formed by nucleotide degradation.
- Adenine phosphoribosyl transferase and hypoxanthine guanine phosphoribosyl transferase salvage free purines.
- Uric acid is the final degradation product of purine nucleotides.
- Uric acid is a normal component of urine, but hyperuricemia can occur.
- Hyperuricemia can result from increased production or decreased excretion of uric acid.
- Hyperuricemia can lead to gout, which can be primary or secondary.
