LLM Analysis

Numerator Metabolite Explanation:

Plasmalogen and glycerophospholipid metabolism.4[1], 5[2]

Denominator Metabolite Explanation:

Endocannabinoid and glycerophospholipid metabolism.6[1], 7[2], 8[3]

Ratio Explanation:

The ratio reflects fatty acid desaturase activity, where FADS2 is involved in converting linoleic acid (a component of the numerator) to arachidonic acid (the denominator).9[1], 10[2], 11[3], 12[4]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variants in FADS1/FADS2 alter the balance of pro-inflammatory and anti-inflammatory long-chain fatty acids.13[1], 14[2] This dysregulation of lipid mediators is linked to an increased risk for inflammatory conditions and metabolic disorders such as cholelithiasis and dyslipidemia, which are observed phenotypes.15[3]

Phenotype Driver:

Gene-centric:FADS1/FADS2
