LLM Analysis

Numerator Metabolite Explanation:

Phospholipid biosynthesis, Glycerophospholipid metabolism.5[1], 6[2], 7[3]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism, Phosphatidylcholine biosynthesis.

Ratio Explanation:

The ratio reflects FADS1 activity, where higher levels indicate a greater conversion of precursor fatty acids, influencing the balance of different phospholipid species.

Ratio Evidence:

metabolites not in a pathway but enzyme catalyzes one metabolite

Gene Ratio Phenotype Relationship:

Genetic variants in FADS1 are associated with altered FADS1 expression and activity, influencing polyunsaturated fatty acid metabolism and cholesterol levels. This alteration in lipid profiles is a known risk factor for pure hypercholesterolaemia and other cardiometabolic diseases.8[1], 9[2], 10[3], 4[4], 11[5], 12[6]

Phenotype Driver:

Gene-centric:FADS1
