LLM Analysis

Numerator Metabolite Explanation:

Glycerophosphoinositol biosynthesis, Polyunsaturated fatty acid metabolism.3[1], 4[2]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism, Fatty acid biosynthesis.5[1]

Ratio Explanation:

The ratio reflects the desaturation of linoleic acid (18:2) precursors to arachidonic acid (20:4), a key step in fatty acid metabolism catalyzed by FADS enzymes.6[1], 7[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

FADS1/FADS2 genetic variants influence the levels of long-chain polyunsaturated fatty acids.6[1], 7[2] Altered levels of these fatty acids are associated with disorders of lipoprotein metabolism and pure hypercholesterolaemia, likely by affecting lipid composition and inflammatory pathways.8[3], 9[4], 10[5], 11[6]

Phenotype Driver:

Gene-centric:FADS1/FADS2
