LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism

Denominator Metabolite Explanation:

Glycerophospholipid metabolism

Ratio Explanation:

The ratio reflects FADS1 enzymatic activity, where a lower ratio suggests decreased conversion of precursor fatty acids, impacting lipid profiles and inflammatory pathways.4[1], 5[2], 6[3]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Reduced FADS1 activity alters fatty acid composition, increasing substrates for inflammatory lipid mediators. This dysregulation is associated with hypercholesterolemia and inflammatory conditions like IBD and dermatitis.7[1], 8[2], 9[3], 10[4], 11[5]

Phenotype Driver:

Gene-centric:FADS1
