LLM Analysis

Numerator Metabolite Explanation:

Glycerophosphoinositol biosynthesis, Polyunsaturated fatty acid biosynthesis.4[1], 5[2]

Denominator Metabolite Explanation:

Glycerophosphocholine biosynthesis, Polyunsaturated fatty acid biosynthesis.6[1], 7[2]

Ratio Explanation:

This ratio reflects the balance of omega-6 to omega-3 fatty acid-containing lipids, modulated by FADS enzyme activity which is crucial for long-chain PUFA synthesis.1[1], 8[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Variants in FADS1/FADS2 alter desaturase activity, impacting the balance of pro- and anti-inflammatory PUFAs and lipid profiles.8[1], 9[2], 10[3] This dysregulation is linked to inflammatory (asthma, IBD) and metabolic (Type 2 diabetes, hypercholesterolemia, cholelithiasis) diseases.11[4], 12[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
