LLM Analysis

Numerator Metabolite Explanation:

Plasmalogen and glycerophospholipid metabolism.6[1], 7[2], 8[3]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism.8[1], 9[2], 10[3]

Ratio Explanation:

The ratio reflects the balance between different classes of ethanolamine-containing glycerophospholipids, influenced by fatty acid desaturase activity which alters the available fatty acid pool.11[1], 12[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Reduced FADS1/FADS2 activity alters the composition of complex lipids like phosphatidylcholines and phosphatidylethanolamines, which can impact membrane fluidity and signaling, contributing to pathologies like cholelithiasis and type 2 diabetes by affecting lipid and glucose metabolism.13[1], 14[2], 15[3], 16[4], 17[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
