LLM Analysis

Numerator Metabolite Explanation:

Fatty acid metabolism.4[1]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism, Fatty acid metabolism.5[1]

Ratio Explanation:

The ratio of a very-long-chain saturated lysophosphatidylcholine to a polyunsaturated phosphatidylcholine likely reflects the activity of FADS enzymes in producing polyunsaturated fatty acids.2[1], 6[2]

Ratio Evidence:

metabolites not in a pathway but enzyme catalyzes one metabolite

Gene Ratio Phenotype Relationship:

Genetic variants in FADS1/FADS2 are linked to altered desaturase activity, affecting polyunsaturated fatty acid levels.7[1], 6[2] This altered lipid profile is associated with an increased risk for pure hypercholesterolemia, type 2 diabetes, and cholelithiasis.8[3], 9[4], 10[5], 11[6], 12[7]

Phenotype Driver:

Gene-centric:FADS1/FADS2
