LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism, Phosphatidylcholine biosynthesis.5[1], 6[2], 7[3]

Denominator Metabolite Explanation:

Fatty acid beta-oxidation, Carnitine shuttle.8[1], 9[2], 10[3]

Ratio Explanation:

The ratio reflects the balance between glycerophospholipid synthesis incorporating polyunsaturated fatty acids and the oxidation of very long-chain saturated fatty acids, modulated by FADS activity.

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Altered FADS1/FADS2 activity dysregulates polyunsaturated fatty acid metabolism, which is reflected in the ratio and contributes to phenotypes like hypercholesterolemia, type 2 diabetes, and cholelithiasis.11[1], 12[2], 13[3], 14[4]

Phenotype Driver:

Gene-centric:FADS1/FADS2
