LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism

Denominator Metabolite Explanation:

Glycerophospholipid metabolism

Ratio Explanation:

The ratio of 1,2-dilinoleoyl-GPC (18:2/18:2) to 1-stearoyl-GPC (18:0) reflects the activity of FADS1/FADS2, which desaturate fatty acids, influencing membrane fluidity and inflammation.3[1], 4[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Reduced FADS1/FADS2 activity, indicated by the ratio, is associated with altered lipid profiles and an increased risk for cholelithiasis and type 2 diabetes.5[1], 6[2], 7[3], 8[4]

Phenotype Driver:

Gene-centric:FADS1/FADS2
