LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid Metabolism

Denominator Metabolite Explanation:

Glycerophospholipid Metabolism

Ratio Explanation:

The ratio reflects the efficiency of converting linoleic acid (18:2) into arachidonic acid (20:4), a process mediated by FADS1 and FADS2 enzymes.3[1], 4[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variation in FADS1/FADS2 alters enzyme activity, impacting the conversion of linoleic to arachidonic acid. This dysregulation of polyunsaturated fatty acids is associated with altered lipid profiles, including hypercholesterolemia, and other cardiometabolic phenotypes.5[1], 6[2], 7[3]

Phenotype Driver:

Gene-centric:FADS1/FADS2
