LLM Analysis

Numerator Metabolite Explanation:

Plasmalogen biosynthesis, Glycerophospholipid metabolism.4[1], 5[2]

Denominator Metabolite Explanation:

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

Ratio Explanation:

The ratio may reflect FADS activity; lower FADS function increases precursor linoleoyl-GPC and decreases complex lipids like plasmalogens, which are rich in FADS products.8[1], 9[2], 10[3]

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Genetic variants in FADS1/FADS2 alter desaturase activity, affecting the balance of polyunsaturated fatty acids.9[1], 11[2] This dysregulation of lipid mediators is linked to inflammation and metabolic disorders such as dyslipidemia, type 2 diabetes, and cholelithiasis.11[3], 12[4], 13[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
