LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism, Linoleic acid metabolism.4[1]

Denominator Metabolite Explanation:

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

Ratio Explanation:

The ratio reflects the balance between glycerophospholipid synthesis utilizing linoleic acid (18:2) and the degradation or alternative synthesis involving stearoyl-GPE (18:0).4[1], 5[2]

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Genetic variants in FADS1/FADS2 alter enzyme activity, impacting the balance of polyunsaturated fatty acids incorporated into phospholipids.8[1], 9[2] This dysregulation is associated with altered blood lipid profiles, including cholesterol levels, linking to hypercholesterolaemia and potentially cholelithiasis.10[3], 11[4]

Phenotype Driver:

Gene-centric:FADS1
