LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism, Phosphatidylethanolamine biosynthesis7[1]

Denominator Metabolite Explanation:

Phosphatidylethanolamine biosynthesis8[1]

Ratio Explanation:

This ratio reflects the conversion of linoleoyl-containing phospholipids to arachidonoyl-containing phospholipids, a key step in polyunsaturated fatty acid metabolism catalyzed by FADS1/FADS2.4[1], 9[2], 10[3]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Reduced FADS1/FADS2 activity, indicated by a higher ratio, is associated with altered lipid profiles, including lower total cholesterol and a decreased risk of asthma, potentially through modulation of inflammatory pathways.11[1], 12[2], 13[3], 14[4], 15[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
