LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism.3[1], 4[2], 5[3]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism.6[1], 7[2]

Ratio Explanation:

This ratio compares a linoleoyl-containing phosphatidylethanolamine to dipalmitoyl-phosphatidylcholine, potentially reflecting desaturase activity (FADS1/FADS2) and resulting phospholipid composition.8[1], 9[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variation in FADS1 alters desaturase activity, impacting polyunsaturated fatty acid levels and phospholipid composition.8[1], 10[2] This influences lipoprotein metabolism, leading to hypercholesterolemia, other dyslipidemias, and associated disorders.11[3], 12[4], 9[5]

Phenotype Driver:

Gene-centric:FADS1
