LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid Metabolism; Omega-6 Fatty Acid Metabolism

Denominator Metabolite Explanation:

Glycerophospholipid Metabolism; Omega-3 Fatty Acid Metabolism

Ratio Explanation:

The ratio reflects FADS1/FADS2 desaturase activity, comparing a key omega-6 product (arachidonic acid, 20:4) with an omega-3 precursor (alpha-linolenic acid, 18:3).1[1], 2[2], 5[3]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Reduced FADS1/FADS2 activity alters the balance of pro-inflammatory omega-6 and anti-inflammatory omega-3 lipids, contributing to metabolic and inflammatory phenotypes like cholelithiasis, type 2 diabetes, and inflammatory skin conditions like follicular cysts.6[1], 7[2], 8[3], 9[4]

Phenotype Driver:

Gene-centric:FADS1/FADS2
