LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism3[1]

Denominator Metabolite Explanation:

Ether lipid metabolism4[1], 5[2]

Ratio Explanation:

The ratio of 1-palmitoyl-2-linoleoyl-gpc to its plasmalogen analogue reflects fatty acid desaturase (FADS) activity, influencing the composition of different phospholipid classes.6[1], 7[2]

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Genetic variation in FADS1/FADS2 alters fatty acid desaturase activity, which modulates the balance of lipid species, including this ratio.1[1], 8[2] This dyslipidemia is associated with hypercholesterolemia and cholelithiasis.9[3], 10[4]

Phenotype Driver:

Gene-centric:FADS1/FADS2
