LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism, Linoleic acid metabolism.3[1], 4[2]

Denominator Metabolite Explanation:

Plasmalogen synthesis, Ether lipid metabolism.5[1], 6[2]

Ratio Explanation:

This ratio reflects the balance between glycerophospholipid synthesis pathways, influenced by FADS1 activity on fatty acid precursors like linoleic acid (18:2) and plasmalogen production.7[1], 8[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variation in FADS1 alters polyunsaturated fatty acid metabolism, impacting the composition of various lipids and influencing plasma cholesterol levels, which contributes to pure hypercholesterolaemia and cholelithiasis.9[1], 10[2], 11[3]

Phenotype Driver:

Gene-centric:FADS1
