LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism, Phosphatidylcholine biosynthesis4[1], 5[2], 6[3]

Denominator Metabolite Explanation:

Sphingolipid metabolism7[1], 8[2], 9[3]

Ratio Explanation:

The ratio reflects the balance between glycerophospholipid and sphingolipid synthesis, influenced by FADS desaturase activity on fatty acid precursors.1[1], 3[2], 10[3], 11[4]

Ratio Evidence:

metabolites not in a pathway but enzyme catalyzes one metabolite

Gene Ratio Phenotype Relationship:

FADS1/FADS2 variants alter fatty acid desaturation, affecting the balance of lipid species, which is associated with dyslipidemia and inflammatory conditions like cholelithiasis.3[1], 12[2], 10[3]

Phenotype Driver:

Gene-centric:FADS1/FADS2
