Uric Acid, Serum
Uric Acid, Serum is a waste product produced by the breakdown of purines in the body. High levels of uric acid can cause gout or kidney stones.
iollo markers that associate with Uric Acid, Serum
Aspartic Acid
Aspartic acid is a precursor for purine bases. Higher aspartate levels may increase purine synthesis and uric acid generation.

Glutamic Acid
Glutamic acid can increase purine nucleotide synthesis via amidophosphoribosyltransferase stimulation, potentially raising uric acid levels.

Glutamine
Glutamine provides nitrogen for increased purine synthesis, which can lead to higher uric acid production when purines are catabolized.

Glycine
Glycine is used in de novo purine synthesis. Increased glycine availability can promote purine production and downstream uric acid formation.

Hypoxanthine
Hypoxanthine is a purine derivative that is oxidized by xanthine oxidase to form xanthine and subsequently uric acid. Elevated hypoxanthine contributes to higher uric acid levels.

Xanthine
Xanthine is a purine base that is oxidized by xanthine oxidase to form uric acid. Increased xanthine levels directly lead to increased uric acid production.
