LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism.5[1], 6[2], 7[3], 8[4]

Denominator Metabolite Explanation:

Endocannabinoid signaling, Glycerophospholipid metabolism.9[1], 10[2], 11[3]

Ratio Explanation:

The ratio reflects the activity of FADS1/FADS2, which influences the conversion of linoleic acid to arachidonic acid, a precursor for the denominator, 1-arachidonylglycerol.12[1], 13[2], 4[3]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Reduced FADS1/FADS2 activity, indicated by a higher ratio, alters fatty acid profiles, which has been linked to variations in cholesterol levels.14[1], 15[2], 16[3], 17[4] The FADS gene cluster is also associated with cholelithiasis and hypercholesterolemia.18[5], 16[6]

Phenotype Driver:

Gene-centric:FADS1/FADS2
