LLM Analysis

Numerator Metabolite Explanation:

Phosphatidylethanolamine biosynthesis3[1]

Denominator Metabolite Explanation:

Endocannabinoid pathway4[1]

Ratio Explanation:

This ratio may reflect the balance between phospholipid incorporation of linoleic acid and its desaturation to arachidonic acid, a precursor for 1-arachidonylglycerol, influenced by FADS1/2 activity.

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

FADS1/FADS2 gene variants influence the efficiency of converting linoleic acid to arachidonic acid.1[1], 2[2] Lower FADS activity is associated with higher levels of precursor lipids and lower levels of arachidonic acid-containing lipids, potentially impacting inflammatory processes and lipid profiles associated with cholelithiasis and hypercholesterolemia.5[3], 6[4]

Phenotype Driver:

Gene-centric:FADS1/FADS2
