LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism

Denominator Metabolite Explanation:

Glycerolipid metabolism, PUFA synthesis.4[1]

Ratio Explanation:

This ratio reflects FADS1/FADS2 activity; these enzymes mediate the conversion of linoleic acid (18:2) to arachidonic acid (20:4), a key step in fatty acid metabolism.2[1], 5[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variation in FADS1/FADS2 alters polyunsaturated fatty acid metabolism, reflected by the ratio. This dysregulation of fatty acids and subsequent inflammatory mediators likely contributes to the risk of cholelithiasis, dyslipidemia, and inflammatory diseases like asthma.6[1], 7[2], 8[3], 9[4]

Phenotype Driver:

Gene-centric:FADS1
