LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism

Denominator Metabolite Explanation:

Arachidonic acid metabolism

Ratio Explanation:

The ratio reflects FADS1/FADS2 enzymatic activity, representing the balance between a linoleic acid-containing lipid and an arachidonic acid-derived lipid.1[1], 2[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variation in FADS1/FADS2 alters polyunsaturated fatty acid metabolism. This impacts cholesterol homeostasis and inflammatory pathways, contributing to the observed associations with cholelithiasis, hypercholesterolemia, type 2 diabetes, and inflammatory conditions like asthma and dermatitis.3[1], 4[2], 5[3], 6[4]

Phenotype Driver:

Gene-centric:FADS1/FADS2
