LLM Analysis

Numerator Metabolite Explanation:

Plasmalogen biosynthesis, Glycerophospholipid metabolism.5[1], 6[2]

Denominator Metabolite Explanation:

Plasmalogen biosynthesis, Glycerophospholipid metabolism.5[1], 7[2]

Ratio Explanation:

The ratio reflects FADS1/FADS2 activity by showing the relative incorporation of linoleoyl (an unsaturated fatty acid) versus palmitoyl (a saturated fatty acid) into plasmalogens.

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variation in FADS1/FADS2 alters PUFA synthesis, reflected in the plasmalogen ratio.1[1], 8[2], 4[3], 9[4] This dysregulation of lipid mediators likely contributes to associated inflammatory and metabolic disorders like asthma, IBD, and hypercholesterolemia.1[5], 10[6], 11[7], 12[8]

Phenotype Driver:

Gene-centric:FADS1/FADS2
